Parallel Structure: Parallelism in Lists, Pairs, Correlatives & Comparisons

Items joined in a list, a pair or a comparison should share the same grammatical shape. This guide covers lists and series, -ing or to, either-or and not only-but also, comparisons, repeated little words, bullet points, and parallelism for rhythm and persuasion, with clear examples, for learners aged 5 to 19.

Words that match

A list joins words together with commas and 'and'. The words in a list should be the same kind of word.

Three kinds of word you already know.

Naming words name a thing, a person or an animal: apples, a bat, cows.

Doing words tell you an action: run, jumped, sing.

Describing words tell you what something is like: tall, sweet, red.
The listThe wordsDo they match?
Meera ate apples, mangoes and grapes.naming, naming, namingyes - three things
Tom can hop, skip and jump.doing, doing, doingyes - three actions
The sky was blue, clear and bright.describing, describing, describingyes - three describing words
Meera ate apples, mangoes and sweet.naming, naming, describingno - 'sweet' is not a thing

The words can be different words. They just need to be the same kind. This is the first move of the match check you will build over the next sections: find the words that are joined, and see if they are the same kind.

Here is a whole box of lists. Some match and some do not. Look at the kind of each word.

The listKinds of wordWhat you hear
We saw lions, tigers and bears.naming, naming, namingsmooth
We saw lions, tigers and loud.naming, naming, describinga bump on 'loud'
Ravi is tall, kind and funny.describing, describing, describingsmooth
Ravi is tall, kind and plays cricket.describing, describing, doinga bump on 'plays cricket'
Asha ran, jumped and laughed.doing, doing, doingsmooth

Every bump comes from the same place: one word in the list is a different kind from the rest.

Notice something else. The matching words do not have to look alike. 'Lions', 'tigers' and 'bears' have different letters and different lengths. 'Tall', 'kind' and 'funny' do not rhyme. What makes them match is the job they do - three animals, three ways Ravi is.

So when you check a list, do not look at the letters. Ask: what kind of word is each one?

Picture a toy train with three carriages. Each carriage can only carry one kind of cargo. If the first carriage carries fruit and the second carries fruit, the third should carry fruit too - mangoes, grapes, bananas. If a carriage full of shoes is hooked on the end, the train still moves, but everyone at the station points and says, 'That one does not belong.' A list is a train of words.

In grown-up grammar, making the words in a list the same kind is called parallel structure, or parallelism. Parallel lines run side by side in the same direction, like train tracks. Parallel words do too: each one does the same kind of job. You will meet the word 'parallel' again in Practice, where the lists get longer and the items get bigger than one word.

Here is a hard one, and it is fine to find it hard. Some words can be more than one kind. 'Dance' can be a thing - 'a dance' - or an action - 'I dance'. 'Fish' can be the animal, or what you do with a rod. So how do you know what kind a word is in a list? Look at its partners. 'We saw lions, tigers and fish.' Lions and tigers are animals, so here 'fish' is an animal too - it matches. 'We swim, run and fish.' Swim and run are actions, so here 'fish' is an action too - it matches again. The same word fitted two different lists, because in each list it did the same job as its partners. So when a word could be two kinds, read the whole list. Ask what the other words are doing, and see if this word can do that same job. The partners tell you which kind it is.

Did you know that matching lists are hiding in songs and rhymes you already know? 'Head, shoulders, knees and toes.' Four body parts - four naming words. Every one matches, and that is part of why it is so easy to sing. Think of a nursery rhyme or a game where things come in threes: 'Ready, steady, go!' has its own rhythm. Or think of how a teacher calls out 'Sit, listen and write.' Three actions, three doing words. Now try breaking one on purpose. 'Head, shoulders, knees and running.' It trips your tongue, and the song stops working. People who make up songs and rhymes know this without being told. Matching words are easier to say, easier to remember and easier to sing.

Matching words do not have to rhyme, start with the same letter, or be the same length. 'Lions, tigers and bears' match because they are all animals, not because they look alike. Some words can be more than one kind - 'dance', 'fish', 'play'. Look at the other words in the list to see which job they are doing. This section looks at lists of single words. Later sections look at bigger items, like 'a bat' and 'a red ball', and at pairs joined by 'or' and 'but'.

  1. Find the list: look for commas and 'and' joining words together.
  2. Say what kind each word is - a naming word, a doing word or a describing word.
  3. Check that every word in the list is the same kind.
  4. Listen for the bump: read the list out loud.
  5. If one word is a different kind, swap it for a word that matches.
  6. Do not worry if the words look different - different words can still be the same kind.
  7. When a word could be two kinds, let the other words in the list decide.
  8. Check the last word most carefully - that is where slips often hide.
  9. Use matching lists in your own stories so they are smooth to read.
  10. Leave a matching list alone - it does not need fixing.
Words joined in a list should be the same kind of word. Naming words go with naming words: apples, mangoes and grapes. Doing words go with doing words: hop, skip and jump. Describing words go with describing words: tall, kind and funny. When one word is a different kind, the list bumps. 'Meera ate apples, mangoes and sweet' - two things and a describing word. Swap it for a thing: 'apples, mangoes and grapes.' Matching words do not have to look alike. They just need to be the same kind. And when a word could be two kinds, like 'fish' or 'dance', the other words in the list tell you which job it is doing. Find the list. Name each word's kind. Make them match. Next: lists of things.

Lists of things

In a list of things, every item is a naming word. The item can have little helpers in front, and it is still a thing.

What can ride along with a thing.

A little word - a, an, the, some, my: a bat, the ball, my cap.

A describing word - red, new, old: a red ball, an old boot.

Both - a new red ball. Still one thing: a ball.
The listEach itemMatch?
a bat, a ball and a capthing, thing, thingyes
a bat, a new red ball and a capthing, thing, thingyes - 'a new red ball' is still a ball
a bat, a ball and plaything, thing, actionno - you cannot pack 'play'
a bat, a ball and sportything, thing, describingno - 'sporty' is not a thing

Find the naming word at the heart of each item. If every item has one, the list matches. This is the match check again: find the list, and see that every item is the same kind - here, a thing.

Here is Aditi's drawing list, checked item by item.

Aditi's sentenceThe itemsThe heart of each itemMatch?
I drew a sun, a tree and a house.a sun / a tree / a housesun, tree, houseyes
I drew a big sun, a tall tree and a house.a big sun / a tall tree / a housesun, tree, houseyes
I drew a sun, a tree and colourful.a sun / a tree / colourfulsun, tree, - noneno
I drew a sun, a tree and my dog Moti.a sun / a tree / my dog Motisun, tree, dogyes

The second sentence has describing words tucked inside - 'big', 'tall'. They do not break the list, because each one sits in front of a thing.

The third sentence has a describing word on its own - 'colourful' - with no thing after it. That is the bump. Aditi could fix it two ways: add a thing ('a colourful kite'), or move the describing word to where it belongs ('I drew a colourful sun, a tree and a house').

In the fourth sentence, the item 'my dog Moti' is long, but its heart is 'dog' - a thing. Long is fine. Different kind is not.

Picture a row of lunchboxes on a table. Each lunchbox must hold a thing you can eat - a roti, an apple, a small cake. Some lunchboxes have a label on the lid, like 'red' or 'fresh', and that is fine - the label is on a box that still holds food. But one lunchbox has only a label and nothing inside. Open it, and there is no thing at all. That empty box is the item that does not match.

In grown-up grammar, an item like 'a new red ball' is called a noun phrase. The noun is the naming word at its heart - 'ball'. The words in front, like 'a', 'new' and 'red', belong to the phrase, but the whole phrase is still a naming item. In Practice you will name each item's shape, and 'noun phrase' is one of the shapes you will use.

Here is a hard one, and it is fine to find it hard. 'Riya bought a pen, a red notebook and red.' The word 'red' appears twice. Once it is inside 'a red notebook', and that is fine - it sits in front of a thing. Once it is on its own at the end, and that is the bump. So the same word can be fine in one place and wrong in another. The question is not 'Is there a describing word here?' The question is 'Does this item have a thing at its heart?' 'A red notebook' - yes, a notebook. 'Red' - no thing at all. To fix it, give the lonely describing word a thing: 'a pen, a red notebook and a red eraser.' Now every item has a thing at its heart, and the list matches. When you check a list of things, look for the naming word in each item. If you cannot find one, that item is the odd one out.

Did you know that shops and menus are full of lists of things - and the good ones usually match? A sweet shop sign might say: 'Laddoos, jalebis, barfis and fresh rasgullas.' Four sweets, four things. 'Fresh' has sneaked in, but it sits in front of 'rasgullas', so the list still matches. Imagine a sign that said: 'Laddoos, jalebis, barfis and delicious.' Customers would read it and wonder: delicious what? People who write signs, menus and labels work hard to keep every item a thing, because a reader has only a second to look. A list of things that matches can be read at a glance.

An item can be one word ('pens') or many ('a new red cricket ball'). What matters is that each item has a thing - a naming word - at its heart. Describing words are welcome inside a list of things, as long as they sit in front of a thing. Some words can be a thing or an action, like 'play' - 'a play at school' is a thing. Look at how the word is used. On its own after 'a ball and', 'play' is an action.

  1. Find the list of things: look for commas and 'and' joining items.
  2. Find the naming word at the heart of each item.
  3. Let little words - a, an, the, some, my - ride along in front.
  4. Let describing words ride along too, as long as a thing comes after them.
  5. If an item has no thing at its heart, it is the odd one out.
  6. Watch for actions at the end of a list of things - 'and play', 'and write'.
  7. Watch for a describing word left on its own - 'and colourful'.
  8. Fix the odd item by swapping in a thing, or by giving the describing word a thing.
  9. Do not worry if items are different lengths - long and short can match.
  10. Read the list out loud and picture each item. Can you point at every one?
In a list of things, every item is a thing - a naming word. A little word can ride along in front: a bat, the ball, my cap. A describing word can ride along too: a red ball, an old boot. The item is still a thing, because a naming word sits at its heart. When an item has no thing at its heart, the list bumps. 'A bat, a ball and play' - 'play' is an action. 'A sun, a tree and colourful' - 'colourful' has lost its thing. Fix it by swapping in a thing - 'a cap' - or by giving the describing word a thing - 'a colourful kite'. Long items and short items can match. Different kinds cannot. Ask of every item: could I point at it? If you can, it is a thing, and it belongs in the list. Next: lists of actions.

Lists of actions

In a list of actions, every item is a doing word. The items should all have the same shape, too.

What an action item can look like.

A doing word on its own - ran, jumped, laughed.

A doing word with words after it - wagged his tail, rolled over, waters the plants.

Doing words that share a helper - Tom can hop, skip and jump. Each one fits after 'can': can hop, can skip, can jump.
The listEach itemMatch?
Anika ran, jumped and laughed.doing, doing, doingyes
Max barked, wagged his tail and rolled over.doing, doing, doingyes - long items are fine
Anika ran, jumped and happy.doing, doing, describingno - 'happy' is not an action
Tom can hop, skip and jumping.doing, doing, -ingno - 'can jumping' does not work

Check every item, and when there is a helper like 'can' or 'will', say it in front of each one. This is the match check again: find the list, and make sure every item is the same kind - here, an action in the same shape.

Here is Zoya's swimming lesson, checked item by item. The list shares one helper - 'can'.

Zoya's sentenceSay each with 'can'Match?
Zoya can swim, dive and float.can swim / can dive / can floatyes
Zoya can swim, dive and floating.can swim / can dive / can floatingno - 'can floating' bumps
Zoya can swim, dive and a float.can swim / can dive / can a floatno - 'a float' is a thing
Zoya can swim, dive and race her brother.can swim / can dive / can race her brotheryes

Saying the helper in front of each item is a handy trick. The helper is shared by the whole list, so every item has to fit with it. 'Can float' fits. 'Can floating' does not, and neither does 'can a float'.

The last sentence has a long item - 'race her brother'. It still fits after 'can', and it is still an action, so it matches.

You will meet this trick again later in the chapter, where it gets a name. For now, remember: say the shared words in front of every item, and listen.

Picture a row of footprints in wet sand. Each footprint is one action: step, step, step. They are all the same shape, so you can follow them easily across the beach. Now picture a row where the third footprint is suddenly a paw print. You stop and stare. Where did the person go? A list of actions is a row of footprints - every print should be the same kind.

In grown-up grammar, an action item like 'wagged his tail' or 'waters the plants' is called a verb phrase - a doing word (the verb) with the words that belong to it. In 'Tom can hop, skip and jump', the helper 'can' is shared by all three verbs. In Practice you will see that shared words are why each item must fit: every item has to work with the words it shares.

Here is a hard one, and it is fine to find it hard. 'Anika ran, jumped and happy' bumps, because 'happy' is a describing word in a list of actions. But what about this? 'Anika ran, jumped and was happy.' Now it sounds fine! Why? Because 'was happy' is not just a describing word any more. 'Was' is a doing word - a quiet one that tells you how someone was. So 'was happy' is an action item, and it fits with 'ran' and 'jumped'. Try it with another: 'The dog ate, slept and hungry' bumps. 'The dog ate, slept and felt sleepy' works, because 'felt' is a doing word. So one small word can change the kind of an item. When a describing word bumps in a list of actions, you can often fix it by adding a doing word in front: was, felt, got, looked. The question is always the same: is each item an action, in the same shape as the others?

Did you know that some of the most famous lines in stories are lists of actions? Think of the old tale of the wolf who went to the little pigs' houses. He huffed, and he puffed, and he blew the house down. Three actions in a row - huffed, puffed, blew - and children all over the world can say them by heart. Why is that line so easy to remember? Partly because every action is the same kind of word, and each one has the same beat. Your ear catches the pattern and holds on to it. Now try breaking it: 'He huffed, and he puffed, and blowing the house down.' The magic is gone. Storytellers have used matching lists of actions for hundreds of years, because they make a scene move - and stick.

Actions can be one word ('ran') or several ('wagged his tail'). Both match, as long as each item is an action in the same shape. Some words can be a thing or an action - 'bow', 'float', 'swim'. Check how the word is used: 'a float' is a thing; 'float' after 'can' is an action. Keeping every action in the same time - all past, all present - is its own topic, in the tense chapter. This section is about the kind of word.

  1. Find the list of actions: look for commas and 'and' joining doing words.
  2. Check that every item is something you can do.
  3. Check that every item has the same shape - no -ing word in a list of plain doing words.
  4. Look for a shared helper like 'can' or 'will' before the list.
  5. Say the helper in front of every item and listen: can swim, can dive, can float.
  6. Let long actions and short actions sit together - 'barked' and 'wagged his tail' match.
  7. Watch for a describing word hiding at the end: 'ran, jumped and happy'.
  8. Watch for a thing hiding at the end: 'sing, dance and a bow'.
  9. To fix a describing word, swap in an action or add a doing word like 'was' or 'felt'.
  10. Read the whole list out loud before you move on.
In a list of actions, every item is a doing word in the same shape. One word or many: 'ran', 'wagged his tail', 'rolled over'. A shared helper: 'Tom can hop, skip and jump' - say 'can' in front of each one. When one item is a different kind, the list bumps. 'Anika ran, jumped and happy' - 'happy' describes. 'Zoya can swim, dive and floating' - 'can floating' does not fit. 'Chloe will sing, dance and a bow' - 'a bow' is a thing. Fix it by swapping in an action in the same shape - 'laughed', 'float', 'bow' - or by adding a doing word: 'was happy'. Find the list. Check every item is an action. Say the helper in front of each. Long or short, every action is a footprint in the same row. Next: lists of describing words.

Lists of describing words

In a list of describing words, every item tells you what someone or something is like.

The 'is' trick. Lists of describing words often come after a word like is, was, looks or feels. Say that word in front of every item.

Ravi is tall. Ravi is kind. Ravi is funny. - all fine.

Ravi is tall. Ravi is kind. Ravi is plays football. - the last one bumps.
The listEach itemMatch?
Ravi is tall, kind and funny.describing, describing, describingyes
The kheer is warm, sweet and creamy.describing, describing, describingyes
Ravi is tall, kind and plays football.describing, describing, actionno - 'is plays football' bumps
The river looked wide, calm and slowly.describing, describing, how wordno - 'looked slowly' bumps

Every item should fit after the shared word, and every item should be a describing word. This is the match check again: find the list, and make every item the same kind - here, what it is like.

Here is Poppy writing about her new puppy. She tries four endings.

Poppy's sentenceSay 'is' in front of the last itemMatch?
My puppy is small, soft and brave.is braveyes
My puppy is small, soft and wags its tail.is wags its tailno - an action
My puppy is small, soft and gently.is gentlyno - a how word
My puppy is small, soft and full of beans.is full of beansyes

The first ending is a describing word, so it fits.

The second is an action. It is true - the puppy does wag its tail - but it is a different kind of item. Poppy can keep it by giving it its own sentence: 'My puppy is small, soft and brave. It wags its tail all day.'

The third is a how word. How words tell you how an action is done - gently, quickly, slowly - so they need an action to go with.

The last ending is several words long - 'full of beans' - but it still describes the puppy (it means lively). A describing item can have words after it, just as a thing or an action can.

Picture a paint palette with little pots of colour. Each pot is one describing word - tall, kind, funny - and you dip your brush in each to paint the same portrait. Now picture a pot that is not paint at all, but a tiny football. You cannot paint with a football. A list of describing words is a palette: every pot must be paint for the same picture.

In grown-up grammar, describing words are called adjectives. An adjective with words after it, like 'good at chess' or 'full of beans', is an adjective phrase. After a word like 'is', 'was', 'looks' or 'feels', a list of adjectives all describe the same person or thing. In Practice you will name each item's shape, and 'adjective' is one of the shapes you will check for.

Here is a hard one, and it is fine to find it hard. 'Grandad is old, wise and good at chess.' The last item has three words - 'good at chess'. There is a naming word inside it: chess. So is it a thing? Is it a describing word? Use the 'is' trick. 'Grandad is good at chess.' That works, and it tells you what Grandad is like - he is good at something. The heart of the item is 'good', a describing word. 'At chess' just tells you what he is good at. So 'good at chess' is a describing item, and the list matches. Now compare: 'Grandad is old, wise and plays chess.' 'Grandad is plays chess' bumps. The heart of this item is 'plays', a doing word. The list changes kind. Two items that both mention chess - one matches, one does not. Look for the heart of each item, and test it with 'is'. The heart decides the kind.

Did you know that many old sayings and descriptions are built on lists of describing words? Think of how people describe a good friend: 'loyal, honest and kind'. Or a lovely day: 'warm, bright and still'. Or the weather in a storm: 'wild, wet and windy'. Listen to that last one. 'Wild, wet and windy' - three describing words, and all three even start with the same sound. They were chosen to match in two ways at once. Writers love lists like this because the reader can hold all three words at once and see one clear picture. Swap one for an action - 'wild, wet and blows hard' - and the picture wobbles. A matching list of describing words is one of the quickest ways to paint a scene.

A describing item can be more than one word: 'good at chess', 'full of beans', 'a bit shy'. The 'is' trick tells you whether it describes. The matching words do not need to start with the same letter or sound alike. 'Tall, kind and funny' match because each one describes Ravi. Describing lists often follow is, was, looks, feels or seems. Say that word in front of each item to test it.

  1. Find the list of describing words: look for commas and 'and' after words like is, was, looks or feels.
  2. Check that every item tells what someone or something is like.
  3. Use the 'is' trick: say the shared word in front of each item.
  4. Watch for an action tacked on the end - 'and plays football'.
  5. Watch for a how word - 'slowly', 'gently' - where a describing word belongs.
  6. Let a describing item have words after it - 'good at chess' still describes.
  7. Find the heart of each item: a describing word, or a doing word?
  8. Fix an odd action by swapping in a describing word, or by giving it its own sentence.
  9. Do not squeeze a whole new sentence into the list.
  10. Read the list out loud to check the picture stays the same.
In a list of describing words, every item tells what someone or something is like. 'Ravi is tall, kind and funny.' 'The kheer is warm, sweet and creamy.' Use the 'is' trick. Say the shared word - is, was, looks, feels - in front of every item. Each one should fit. When one item is a different kind, the list bumps. 'Ravi is tall, kind and plays football' - an action. 'The river looked wide, calm and slowly' - a how word. Fix it by swapping in a describing word - 'sporty', 'slow' - or by giving the action its own sentence. A describing item can be long: 'good at chess', 'full of beans'. The heart of the item decides its kind. Every item is paint for the same picture: what someone or something is like. Next: -ing with -ing.

-ing with -ing

An -ing word is a doing word with -ing on the end: draw - drawing, sing - singing, swim - swimming. In a list that starts with -ing words, every item takes -ing.

Three shapes that do not mix in one list.

-ing shape - dancing, flying kites.

'to' shape - to dance, to fly kites.

plain shape - dance, fly kites.

Pick the shape the list starts with, and keep it.
The listShapesMatch?
Priya likes drawing, singing and dancing.-ing, -ing, -ingyes
Arun enjoys flying kites, reading comics and playing cricket.-ing, -ing, -ingyes - long -ing items are fine
Priya likes drawing, singing and to dance.-ing, -ing, tono - 'to dance' wears a different shape
Ellie is good at running, jumping and climb.-ing, -ing, plainno - 'good at climb' bumps

This is the match check again: find the list, name each item's shape, and make them match - here, -ing with -ing.

Here is Arun's holiday list, checked item by item. Each item is an -ing word with words after it.

Arun's sentenceThe itemsShapesMatch?
I enjoyed flying kites, reading comics and playing cricket.flying kites / reading comics / playing cricket-ing, -ing, -ingyes
I enjoyed flying kites, reading comics and to play cricket.flying kites / reading comics / to play cricket-ing, -ing, tono
I enjoyed flying kites, reading comics and cricket playing.flying kites / reading comics / cricket playing-ing, -ing, back to frontno

In the first sentence, every item starts with an -ing word and then says what: flying kites, reading comics, playing cricket. Same pattern, three times.

In the second, the last item switches to 'to'. The meaning is the same, but the shape is different.

In the third, the last item has the -ing word, but in the wrong place - 'cricket playing' is back to front. The first two start with the -ing word, so the third should too.

So matching is not only about the ending. It is about the whole pattern of the item: -ing word first, then the rest.

Picture a row of beads on a string, and every bead has a little tail - the -ing. Draw-ing, sing-ing, danc-ing: each bead has its tail, so the string looks even. Now one bead has a little hat instead - 'to' - sitting on the front. You can see at once that it is the odd bead. To fix the string, take off the hat and give it a tail: to dance becomes dancing.

In grown-up grammar, an -ing word used like this is called a gerund, and an -ing word with the words after it - 'flying kites' - is an -ing phrase. A 'to' word like 'to dance' is called a to-infinitive, or a to-phrase. Both shapes can follow words like 'like' and 'love', which is exactly why they get mixed up. In Practice you will see that a list can also be all 'to' phrases - the rule is the same: pick one shape and keep it.

Here is a hard one, and it is fine to find it hard. Not every word that ends in the letters i-n-g is an -ing word. 'Meera found a ring, a string and a spring.' Ring, string, spring - all end in -ing. But try taking the -ing off. R? Str? Spr? None of those is a doing word. So these are not -ing words at all. They are things - naming words - and the list matches as a list of things. Now try: 'Meera likes swinging, sliding and skipping.' Take off -ing: swing, slide, skip. Each one is a doing word. These are real -ing words, and the list matches as an -ing list. So here is a quick test for an -ing word: take off the -ing (and put back any letter you dropped). If a doing word is left - sing, dance, swim - it is an -ing word. If nothing sensible is left - r, str, spr - it is not. The letters at the end can fool your eyes. The test does not get fooled.

Did you know that people often describe their hobbies and jobs as -ing lists without noticing? Ask someone what they did on holiday, and you might hear: 'Swimming, eating and sleeping!' Three -ing words, said with a laugh. Think of a chore chart on a kitchen wall that gives each day of the week a job: washing on Monday, ironing on Tuesday, baking on Wednesday... Each day gets an -ing job, and the pattern makes the chart easy to read and remember. Now listen to a sports coach: 'Running, passing, shooting - that is all we are practising today.' Coaches use -ing lists because every item sounds like part of one plan. Once you start listening for -ing lists, you will hear them everywhere: at school, at home, on the radio. And you will also start to hear the odd 'to' that sneaks in.

Words like 'like', 'love' and 'hate' can take the -ing shape or the 'to' shape. Both are fine on their own. The slip is mixing them in one list. A list of 'to' words can match too - that comes in Practice. In this section, the lists start with -ing, so every item takes -ing. Words such as 'ring', 'king' and 'string' end in the letters -ing but are naming words, not -ing words.

  1. Find the list, and look at the shape of its first item.
  2. If the first item ends in -ing, every item should end in -ing.
  3. Watch for a 'to' word at the end - 'and to dance'.
  4. Watch for a plain doing word at the end - 'and climb'.
  5. Say the shared words in front of every item: 'good at running', 'good at climbing'.
  6. Keep the -ing word at the front of each item: 'playing cricket', not 'cricket playing'.
  7. Let long -ing items and short ones sit together.
  8. Spell -ing words with care: swimming, dancing, running.
  9. Take off -ing to check a word really is an -ing word.
  10. Read the list out loud - every item should end with the same little tail.
When a list starts with -ing words, every item takes -ing. 'Priya likes drawing, singing and dancing.' 'Arun enjoys flying kites, reading comics and playing cricket.' The items can be short or long, but each one wears the -ing shape, with the -ing word at the front. When one item wears a different shape, the list bumps. 'Drawing, singing and to dance' - a 'to' word. 'Good at running, jumping and climb' - a plain doing word. 'Flying kites, reading comics and cricket playing' - back to front. Fix it by giving the odd item the -ing tail, at the front: dancing, climbing, playing cricket. And check for words like 'ring' and 'king', which end in the letters -ing but are things. Take off the -ing: if a doing word is left, it is an -ing word. Next: pairs with and, or, but.

Pairs with and, or, but

A pair is two items joined by and, or or but. The two items should be the same kind.

Look at both sides of the joining word.

Left side: what kind is it?

Right side: is it the same kind?

Then say the shared words in front of each side: 'want tea', 'want coffee'; 'was slow', 'was steady'.
The pairLeft sideRight sideMatch?
tea or coffeethingthingyes
slow but steadydescribingdescribingyes
We can walk or cycle.actionactionyes
We can walk or cycling.action-ingno - 'can cycling' bumps
Mum was tired but happiness.describingthingno - 'was happiness' bumps

'And', 'or' and 'but' mean different things - 'but' shows a surprise - yet the matching rule is the same for all three. This is the match check again: find the joint, check the kind on each side, and make them match.

Here are some pairs from Rahul's morning, checked side by side.

Rahul's sentenceThe jointSay the shared words with each sideMatch?
I can walk or cycle to school.orcan walk / can cycleyes
My bag is heavy but useful.butis heavy / is usefulyes
I packed a pen and a ruler.andpacked a pen / packed a ruleryes
I can walk or cycling to school.orcan walk / can cyclingno
My bag is heavy but usefully.butis heavy / is usefullyno

Notice that the shared words sit on one side of the pair - 'I can', 'My bag is' - but they belong to both items. That is why saying them in front of each side works so well.

Notice too that the joining word does not change the rule. 'Or' offers a choice, 'but' shows a surprise, 'and' simply adds. Whichever one you use, both sides must be the same kind.

Picture a see-saw in the park. A child sits on each end, and the see-saw goes up and down smoothly. The joining word - and, or, but - is the middle of the see-saw. Now imagine a child on one end and a bag of shopping on the other. It does not work the same way at all. A pair of words is a see-saw: the same kind of thing on each end, balanced across the middle.

In grown-up grammar, 'and', 'or' and 'but' are called coordinating conjunctions, and joining two items with one of them is called coordination. Each item joined is a conjunct. Whatever the conjunction means - adding, choosing or contrasting - the conjuncts should be the same shape. What these little words mean is its own chapter; here you only check the shapes on each side.

Here is a hard one, and it is fine to find it hard. Sometimes each side of a pair is a whole little sentence. 'Riya sang and Dev danced.' Left side: 'Riya sang' - a doer and a doing word. Right side: 'Dev danced' - a doer and a doing word. Each side is a tiny sentence, and the two tiny sentences match. Now try: 'Riya sang and Dev dancing.' The right side has a doer, but its doing word has lost its shape - 'Dev dancing' is not a sentence on its own. The pair bumps. So pairs can be two words, two groups of words, or two whole little sentences. The question is always the same: are both sides the same kind? Here is a clue for the hard ones. Cover the left side and read the right side alone. Then cover the right side and read the left side alone. If each side works in the same way - two things, two actions, two little sentences - the pair matches.

Did you know that English is full of famous pairs that people say without thinking? Bread and butter. Salt and pepper. Up and down. Rain or shine. Slow but steady. Every one of them matches. Bread and butter - two things. Up and down - two directions. Rain or shine - two kinds of weather. Slow but steady - two describing words. These pairs have been said so often that they feel like one word. Part of the reason they have lasted is that both sides match, so they are easy to say and easy to remember. Try breaking one: 'Salt and peppery.' 'Rain or shining.' They sound wrong at once, because your ear already knows the matching version. The next time you hear a pair that everyone uses, check both sides. You will almost always find a perfect match.

'And', 'or' and 'but' mean different things, and choosing between them is a different topic. Here you only check that both sides match. Each side of a pair can be one word ('tea'), a group of words ('a pen'), or a whole little sentence ('Riya sang'). The two sides do not need to be the same length. 'Small but full of energy' matches - both sides describe.

  1. Find the joining word: and, or or but.
  2. Look at the item on its left, then the item on its right.
  3. Say what kind each side is - thing, action, describing word or -ing word.
  4. Say the shared words in front of each side: 'can walk', 'can cycle'.
  5. Watch for a how word next to a describing word - 'slow but steadily'.
  6. Watch for an -ing word next to a plain doing word - 'walk or cycling'.
  7. Watch for a thing next to a describing word - 'tired but happiness'.
  8. Use the same rule for and, or and but.
  9. Let the two sides be different lengths, as long as they are the same kind.
  10. Slow down on short pairs - they are the easiest to miss.
A pair is two items joined by and, or or but. Both sides should be the same kind. Two things: 'tea or coffee'. Two actions: 'We can walk or cycle.' Two describing words: 'slow but steady', 'tired but happy'. Two -ing words: 'reading and writing'. Two little sentences: 'Riya sang and Dev danced.' When the two sides are different kinds, the pair bumps. 'Tea or hot' - a thing and a describing word. 'Walk or cycling' - a plain doing word and an -ing word. 'Slow but steadily' - a describing word and a how word. Say the shared words in front of each side to test it. The joining word can change - and, or, but - but the rule does not. Short pairs are easy to miss, so slow down and look at both ends of the see-saw. Next: the odd one out.

The odd one out

The odd one out is the item in a list or pair that is a different kind or shape from the others.

How to hunt it.

1. Name each item. Thing, action, describing word, -ing word, or 'to' word?

2. Find the pattern. Which kind do most items share?

3. Spot the one that breaks it - first, middle or last - and change it to match.

reading, writing and to paint-ingto paintlastpainting
a torch, sleepy and a blanketthingssleepymiddlea pillow
to act, singing and dancing-ingto actfirstacting
busy, noisy and colourfuldescribingnone-leave it alone

Notice the last row: sometimes there is no odd one out, and the right answer is to leave the list alone. This is the match check again, as a hunt: name each item, find the pattern, and fix the one that breaks it.

Here is a page from a class newsletter, hunted item by item.

Newsletter sentenceItems namedOdd one outFixed
This term we read, wrote and painting.action, action, -ingpainting (last)read, wrote and painted
Our class rabbit is small, fur and gentle.describing, thing, describingfur (middle)small, furry and gentle
Sports day had races, games and prizes.thing, thing, thingnoneleave it alone
We love to sing, dancing and drumming.to, -ing, -ingto sing (first)singing, dancing and drumming

Look at the fixes. In each one, only the odd item changed. The other items already shared a pattern, so the quickest fix is to bring the odd one into line.

Look at the third row too. A hunter who expects to find something might 'fix' this list by mistake. Races, games and prizes are all things. There is nothing to hunt.

And look at the second row: 'fur' and 'furry' are nearly the same word. The odd one out can be just one ending away from matching.

Picture a row of ducks swimming across a pond, all facing the same way. Your eyes slide along the row easily. Then one bird is a goose, or one duck is swimming backwards. It might be at the front, in the middle or at the back, but it stands out once you look at every bird. A list is a row of ducks. Look at them all, and the odd one out gives itself away.

In grown-up grammar, a list with an odd one out is said to have faulty parallelism, or to be not parallel. Fixing it - bringing the odd item into the same shape as the others - is called making the list parallel. Editors spot faulty parallelism by the same steps you have just used: name each item's shape, find the shared pattern, and change the item that breaks it.

Here is a hard one, and it is fine to find it hard. What if the list has four items, and two are one kind and two are another? 'Mira likes running, jumping, to skip and to hop.' Two -ing items. Two 'to' items. Which ones are the odd ones out? Here, look at how the list starts. The first item - 'running' - sets the pattern the reader expects. So the two 'to' items are the ones to change: 'running, jumping, skipping and hopping.' Now try a list with no clear pattern at all: 'Mira likes running, to skip and hop.' Three items, three different shapes. There is no 'odd one' - every item is odd! In a list like that, choose one shape and make every item wear it. The first item is a good guide: 'running, skipping and hopping.' So when most items share a pattern, change the odd one. When there is no clear pattern, pick one - usually the first item's - and use it for them all.

Did you know that 'odd one out' puzzles are one of the oldest kinds of puzzle there is? Apple, banana, carrot, mango - which is the odd one out? The carrot, because it is a vegetable. Children all over the world play games like this, and so do grown-ups in quiz books. Here is the surprise: a list with a grammar slip is the same puzzle. 'Apple, banana, crunchy, mango.' The odd one out is 'crunchy' - not because it is a vegetable, but because it is a different kind of word. So the next time you solve an odd-one-out puzzle about fruit or animals, you are practising exactly the skill that finds grammar slips. Your brain is already good at it. Now you are pointing it at words.

Sometimes there is no odd one out. A list where every item matches should be left alone. The odd one out can sit anywhere - first, middle or last. Check every item. When most items share a pattern, change the odd one. When no pattern is clear, choose one shape - often the first item's - and use it for every item. A long item is not odd just for being long. 'Painting pictures' matches 'reading' and 'writing'.

  1. Name every item in the list - not just the last one.
  2. Say what kind or shape each item is.
  3. Find the pattern that most items share.
  4. Spot the item that breaks the pattern, wherever it sits.
  5. Change the odd item to match the others - one change is usually enough.
  6. Check nearly-matching words carefully: 'fur' or 'furry'?
  7. Do not call an item odd just because it is longer.
  8. If there is no clear pattern, use the first item's shape for every item.
  9. If every item matches, leave the list alone.
  10. Read the fixed list out loud to hear that it now runs smoothly.
The odd one out is the item that is a different kind or shape from the others. It can hide anywhere. Last: 'reading, writing and to paint' - 'to paint'. Middle: 'a torch, sleepy and a blanket' - 'sleepy'. First: 'to act, singing and dancing' - 'to act'. Hunt it in three moves. Name every item. Find the pattern most items share. Spot the one that breaks it - and change that one to match: painting, a pillow, acting. Sometimes there is no odd one out. 'Busy, noisy and colourful' - leave it alone. If there is no clear pattern, choose one shape - the first item's is a good guide - and make every item wear it. Check every duck in the row, change only the odd one, and leave a good row alone. Next: the Match Test.

The Match Test

Here is the Match Test. It has three steps.

Step 1 - Find the joint. Where are items joined? Look for and, or, but, or a list with commas.

Step 2 - Name each item's shape. Is it a thing, an action, a describing word, an -ing word or a 'to' word?

Step 3 - Make them match. Change the item that breaks the pattern. Then say the shared words in front of each item - the drop test - to check it fits.
The sentenceStep 1: jointStep 2: shapesStep 3: drop testResult

Joint, shape, match. The match check you have been building since Section 1 now has its name, and every section from here comes back to the Match Test.

Here is the test on a longer piece - Anaya's diary.

Anaya's sentenceStep 1: jointStep 2: shapesStep 3
Today was sunny, warm and bright.a listdescribing x3passes
I had toast or porridge for breakfast.orthing, thingpasses
After school I went swimming, cycling and to skate.a list-ing, -ing, tofix - 'skating'
My brother was grumpy but funny.butdescribing, describingpasses
We ate rice, dal and delicious.a listthing, thing, describingfix - 'curd'

Step 1 finds a joint in every sentence - three lists and two pairs.

Step 2 names the shapes. Three sentences have one shape all the way through. Two do not.

Step 3 treats them differently. It fixes 'to skate' and 'delicious', and it leaves the other three alone. That is why the test has a Step 3 and not just a 'change something' step: it tells you exactly which item to change, and it stops you changing what is not broken.

Notice the drop test at work in the fixes. 'Went to skate' might sound possible on its own, but 'went swimming, cycling and to skate' does not match; 'ate delicious' does not work at all.

Picture a row of empty jam jars on a shelf, each with a label: 'thing', 'thing', 'thing'. Every item in a list is a spoonful you drop into a jar. Step 1 finds the row of jars. Step 2 reads the label on each spoonful. Step 3 checks that every spoonful matches its jar's label - and if one does not, you swap it for one that does. A shelf of matching jars is a list that passes.

In grown-up grammar, the joint is where coordination happens - where and, or or but joins items. Naming each item's shape is naming its grammatical form. And saying the shared words in front of each item is called the drop test: you drop each item, one at a time, into the place after the shared words. In Practice, the Match Test will work on bigger items - whole phrases and clauses - and on new joints like either-or.

Here is a hard one, and it is fine to find it hard. 'Dadi's garden is full of roses, and she loves weeding, watering and to pick flowers.' There are two joints here! Step 1 finds both: the first 'and' joins two whole little sentences - 'Dadi's garden is full of roses' and 'she loves weeding...'. The second 'and' ends a list: weeding / watering / to pick flowers. Run the test on each joint separately. Joint one: two little sentences - each has a doer and a doing word. They match. Joint two: -ing, -ing, 'to'. The drop test: 'loves weeding', 'loves watering', 'loves to pick flowers'. Each might sound possible alone - but the list started in -ing, so the last item is the odd shape. Fix: 'picking flowers'. So a long sentence can hold more than one joint. Find them all in Step 1, then test each joint on its own. Do not mix up the items of one joint with the items of another.

Did you know the Match Test works on things that are not sentences at all? Look at a menu: 'Samosas - Pakoras - Jalebis - Hot and Spicy.' Step 1: a list. Step 2: thing, thing, thing, describing. Step 3: fix it - 'Chaat', perhaps. Look at a sign on a playground gate: 'No bikes, no dogs, no shouting.' Step 1: a list. Step 2: each item is 'no' and then a thing or an -ing word. Look closely - 'shouting' is an -ing word among things! But on a sign, 'no shouting' is the everyday way to say it, and every item still follows 'no'. Signs have their own habits. Now look at the rules on your classroom wall. 'Listen, share and be kind.' Three actions. It passes. The test goes wherever lists go - menus, signs, rules, labels, songs. Once you carry it with you, you start running it everywhere.

Some sentences have more than one joint. Find them all, and test each one separately. The drop test helps most when there are shared words before the list - is, can, good at, likes. With no shared words, use Step 2's shapes. Signs and menus sometimes follow their own habits, like 'No bikes, no dogs, no shouting.' The test works best on full sentences.

  1. Step 1: find the joint - and, or, but, or a list with commas.
  2. If there is more than one joint, test each one on its own.
  3. Step 2: name each item's shape - thing, action, describing word, -ing word or 'to' word.
  4. Find the shape most items share.
  5. Step 3: change the item that breaks the pattern.
  6. Use the drop test: say the shared words in front of each item.
  7. Check your fix with the drop test too.
  8. If every item has the same shape, the sentence passes - leave it alone.
  9. Say your reason in three parts: joint, shapes, fix.
  10. Run all three steps, in order, on every list or pair you check.
The Match Test has three steps. Step 1 - Find the joint. Look for and, or, but, or a list with commas. Step 2 - Name each item's shape. Thing, action, describing word, -ing word or 'to' word? Step 3 - Make them match. Change the item that breaks the pattern. Then say the shared words in front of each item - the drop test - to check it fits. 'Zara is good at painting, singing and to dance' - a list; -ing, -ing, to; 'good at to dance' bumps; fix: 'dancing'. 'Would you like idli or dosa?' - 'or'; thing, thing; it passes. A sentence can have more than one joint - test each one. And a sentence that passes should be left alone. Joint, shape, match. Every section from here uses it. Next: steps that match.

Steps that match

An instruction tells someone what to do, one step at a time. Each step should start with a doing word, as an order, and every step should have the same shape.

How a matching step looks.

A doing word first - wash, peel, chop.

Then anything it needs - wash the carrots, cut the edges.

Shared words fit every step - in 'Wash, peel and chop the carrots', 'the carrots' goes with all three.
The instructionHow each step startsMatch?
Wash, peel and chop the carrots.doing, doing, doingyes
Mix the flour, crack the eggs and stir the batter.doing, doing, doingyes
Wash, peel and chopping the carrots.doing, doing, -ingno - fix: 'chop'
Wash, peel and you chop the carrots.doing, doing, 'you'no - fix: 'chop'

Run the Match Test on every instruction: find the joint, name how each step starts, and make every step start with a doing word in the same shape.

Here is Kabir's recipe for his dadi's chai, run through the Match Test.

Kabir's stepsHow each step startsStep 3
1. Boil the water.doing word - boilmatches
2. Add the tea leaves and ginger.doing word - addmatches
3. Pouring in the milk.-ing word - pouringfix: 'Pour in the milk.'
4. The sugar goes in now.a thing - the sugarfix: 'Add the sugar.'
5. Strain it into cups.doing word - strainmatches

Numbered steps are a list too - just a list that runs down the page instead of along a line. The Match Test works the same way. Find the pattern most steps share: they start with a doing word, as an order. Then fix the steps that break it.

Step 3 has become an -ing word. Step 4 starts with a thing and describes what happens instead of telling the reader what to do. Both are easy to fix: turn them into orders that start with a doing word.

Now read the fixed recipe aloud: Boil. Add. Pour. Add. Strain. Every step is a call to action. That is what makes a recipe easy to follow with a hot pan in your hand.

Picture a row of stepping stones across a stream. Each stone is a step in the instruction, and each is the same flat shape, so your feet land safely every time: wash, peel, chop. Now picture one stone that is round and wobbly - 'chopping', or 'you chop'. Your foot hesitates before it lands. Matching steps are flat stones in a row. The reader crosses without looking down.

In grown-up grammar, a sentence that gives an order is called an imperative. It starts with the plain doing word - wash, peel, chop - and the 'you' is understood, not said. A list of imperative steps is parallel when every step is an imperative. In Practice you will see the same idea in bullet points and headings, where every item should start the same way.

Here is a hard one, and it is fine to find it hard. 'Wash, peel and chop the carrots.' The words 'the carrots' come at the end, after 'chop'. But they belong to all three steps: wash the carrots, peel the carrots, chop the carrots. They are shared. Now try: 'Wash, peel and boil the water.' Same shape. But say the shared words with each step. 'Wash the water'? 'Peel the water'? That does not make sense! The words at the end only fit the last step. So when the steps need different things, give each step its own words: 'Wash and peel the carrots, and boil the water.' Or: 'Wash the carrots, peel them and boil some water.' This is the drop test from the Match Test, working on instructions. Say the shared words with every step. If they fit every step, sharing is fine. If they fit only one, each step needs its own words. Matching steps is not only about the first word. It is also about what every step shares.

Did you know that some of the most useful sayings in the world are matching instructions? Before crossing a road, many children are taught three steps: 'Stop, look and listen.' Three doing words, each one an order, each one a single beat. It is short enough to remember when a car is coming. Think of a fire-safety instruction many schools teach for when clothes catch fire: stop, drop and roll. Three matching steps again. Even games do it. 'Ready, steady, go!' has its own rhythm, and so does a dance teacher's 'Step, turn and clap!' Why do these last so well? Because matching steps are quick to say and easy to remember, and in a hurry, that matters more than anything. Nobody would teach 'Stop, look and listening' - the pattern would fall apart.

Instructions often use extra words like 'first', 'then' and 'next'. These help the order and do not break the match: 'First wash, then peel, then chop.' Numbered steps are a list too, and each step should start the same way. Not every step needs the same words after its doing word. 'Boil the water. Add the leaves.' Each step can have its own things, as long as each starts with a doing word.

  1. Find the steps: look for commas and 'and', or numbered lines.
  2. Check that every step starts with a doing word.
  3. Keep every step an order - wash, peel, chop.
  4. Watch for an -ing word creeping in - 'and chopping'.
  5. Watch for 'you' in front of one step - 'and you chop'.
  6. Watch for a step that starts with a thing - 'the batter is stirred'.
  7. Say any shared words with every step to check they fit.
  8. If the shared words fit only one step, give each step its own words.
  9. Let 'first', 'then' and 'next' help the order - they do not break the match.
  10. Read the steps aloud: each should sound like a call to do something.
In an instruction, every step should start the same way - with a doing word, as an order. 'Wash, peel and chop the carrots.' 'Mix the flour, crack the eggs and stir the batter.' 'Stop, look and listen.' When one step changes shape, the instruction bumps. 'Wash, peel and chopping' - an -ing word. 'Stop, look and you listen' - a 'you' sentence. 'Crack the eggs and the batter is stirred' - a step that starts with a thing. Fix it by making the odd step an order: chop, listen, stir the batter. Numbered steps are a list too. And words shared at the end - 'the carrots' - must fit every step. If they fit only one, give each step its own words. The Match Test works on instructions: joint, shape, match. Next: first mixed review.

First mixed review

Everything from Discover, in one table. One test works on all of it: the Match Test.

Step 1 - Find the joint. and, or, but, a list, or numbered steps.

Step 2 - Name each item's shape. Thing, action, describing word, -ing word, 'to' word, order.

Step 3 - Make them match. Change the odd one out. Say the shared words in front of each item to check. If every item matches, leave it alone.

Six kinds of list, one test. Joint, shape, match - every time.

Here is a whole paragraph from Isha's school diary. It has four joints. Run the Match Test on each one.

Isha's sentenceStep 1Step 2Step 3
On Saturday I painted, sang and baked.a listaction x3passes
My painting was bright, bold and had flowers.a listdescribing, describing, actionfix - 'bright, bold and flowery'
Mum asked, 'Tea or coffee?'orthing, thingpasses
I love painting, singing and to bake.a list-ing, -ing, tofix - 'baking'

Two sentences passed and two needed one change each. Notice how different the slips were - an action among describing words, and a 'to' word among -ing words - and how the same three steps found both.

Notice too that the first and last sentences are about the same things - painting, singing, baking. In the first they are actions; in the last they are -ing words. Both can match. What matters is that each list keeps to one shape.

And the fixes changed as little as possible: one item, brought into line with the rest.

Picture a big sorting tray with many little boxes - one for things, one for actions, one for describing words, one for -ing words, one for steps. A mixed-up pile of lists lands on the table. You pick up each list, look at its items, and drop it in the right box. If one item in a list belongs in a different box, you swap it before the list goes in. At the end, every box holds lists that match.

Everything in Discover has been one idea: parallel structure, or parallelism - joined items share the same grammatical shape. In Practice, the items grow. You will name each item's shape with grown-up labels - noun phrase, -ing phrase, to-phrase, adjective, prepositional phrase, clause - and meet new joints: either-or, not only-but also, and comparisons with 'than' and 'as'. The Match Test stays the same.

Here is a hard one, and it is fine to find it hard. 'Grandma likes gardening, cooking and to sit in the sun.' Step 1: a list after 'likes'. Step 2: -ing, -ing, and 'to sit in the sun' - a 'to' word. Step 3: the odd one out is 'to sit in the sun'. Fix: 'sitting in the sun'. That one you can do. Now try this. 'Grandma likes gardening and cooking, and she sits in the sun every evening.' Is that a slip? Step 1 again - carefully. There are two joints. The first 'and' joins 'gardening' and 'cooking' - two -ing words, a match. The second 'and' joins two whole little sentences: 'Grandma likes gardening and cooking' and 'she sits in the sun every evening'. Each has a doer and a doing word. A match again. So the second sentence passes! It has the same words as the slip, more or less - but 'she' makes the last part a sentence of its own, joined to another sentence. Step 1 is the key. Find every joint, and work out what each one joins, before you decide anything is wrong.

Did you know you have learned the same skill that editors, teachers and writers use every day? When an editor at a newspaper checks a story, one of the things they look for is lists that do not match. When a teacher marks a composition, 'swimming, cycling and to run' is one of the slips they circle. When a writer reads their own draft aloud, a bump in a list is one of the things their ear catches. They all do it the way you now do it: find where items are joined, look at the shape of each item, and bring the odd one into line. You started this band hearing that 'apples, mangoes and sweet' sounded wrong. Now you can say why, point to the item, and fix it in one move. That is not a small thing. It is a skill that stays with you for as long as you read and write.

Some sentences have more than one joint. Test each one separately before deciding anything is wrong. Some words can be two kinds - 'fish', 'dance', 'play'. Let the other items in the list decide. Practice will add bigger items - whole phrases and clauses - and new joints. The three steps will not change. A list that already matches is a right answer too. Leaving it alone is part of the test, not a failure to find something.

  1. Step 1: find every joint - and, or, but, lists and numbered steps.
  2. Work out what each joint joins before you judge it.
  3. Step 2: name the shape of every item, not just the last.
  4. Decide what kind of list it is: things, actions, describing, -ing, steps or a pair.
  5. Use the check that fits: 'is' for describing lists, 'can' for actions, -ing for -ing lists.
  6. Step 3: change only the odd one out.
  7. Say the shared words in front of each item to check your fix.
  8. Leave a list alone when every item matches.
  9. Say your reason in three parts: joint, shapes, fix.
  10. Read the fixed sentence aloud - it should run without a bump.
Discover in one idea: joined items should match. Things with things: 'a torch, a map and a rope'. Actions with actions: 'Meena can knit, sew and embroider.' Describing words together: 'big, red and light'. -Ing with -ing: 'running, jumping and throwing'. Pairs that match: 'cold but cheerful', 'jam or honey'. Steps that start the same way: 'Stir, taste and serve.' The odd one out can hide anywhere, and it can be any kind of slip. One test finds it. The Match Test: find the joint, name each item's shape, make them match - and say the shared words in front of each item to check. A list that passes stays as it is. A sentence with two joints gets two tests. You can make a list match. Next: Practice - naming each item's shape.

Naming each item's shape

An item is one of the things joined in a list or pair. Its shape is the kind of phrase it is - and you judge the whole item, not just its first word.

ShapeHow to spot itSounds like
noun phrasea naming word, often with a, the or mya torch, a map
-ing phrasestarts with an -ing doing wordflying kites, reading comics
to-phraseto + a doing wordto fly a kite
verb phrasea doing word that tells what someone did or doesran fast, won the race
adjectivea describing wordsmall, noisy
prepositional phrasein, on, by, under, to + a place or thingin the park, to the bank
clausehas its own subject and verbthat the bus was late

This is step two of the Match Test: once you have found the joint, name each item's shape before you decide anything.

Same first word does not mean same shape. Different first words do not mean different shapes.

The word 'to' is the best trap for this section, because it starts two different shapes.

ItemWhat follows 'to'Shape
to the banka placeprepositional phrase
to buy fruita doing wordto-phrase
to Nania personprepositional phrase
to swim every daya doing wordto-phrase

So 'We went to the market, to the bank and to buy fruit' mixes two shapes that happen to share a first word. The fix is to keep all places ('to the market, the bank and the fruit stall') or to move the purpose out of the list ('We went to the market and the bank to buy fruit').

The -ing ending is a smaller trap. 'Swimming' is an -ing phrase in 'I like swimming', but 'a swimming pool' is a noun phrase: the -ing word only describes the pool. Read the whole item and ask what it names or does.

A quick check for each item: could you put 'the thing is' in front of it (noun phrase), 'I like' (an -ing or to-phrase), 'she' (a verb phrase), 'very' (an adjective), or 'it happened' (a prepositional phrase of place or time)? The frame that fits tells you the shape.

Name the whole item. The first word can lie; the whole item cannot.

Picture a row of shoeboxes on a shelf, one for each item in the list. On every lid you stick a label: noun phrase, -ing phrase, to-phrase, place phrase. You do not judge a box by the sticker on its corner - the first word - but by what is inside it. When every lid says the same thing, the shelf is tidy. When one lid says something different, that is the box to open and repack.

Items can be long, and length does not change the shape. 'A torch' and 'a big steel torch with a red strap' are both noun phrases. 'Running' and 'running round the playground before school' are both -ing phrases. So a list can match even when one item is much longer than the others. When you box an item, keep going until the next joining word - a comma, 'and', 'or' - and then name the shape of the whole box.

Here is a case where two different labels are both fine. 'Dr Rao is a surgeon and proud of it.' Name the shapes: 'a surgeon' is a noun phrase; 'proud of it' is an adjective phrase. Two labels, and yet careful writers accept this sentence. Why? Because both items do the same job. Each one tells you something about Dr Rao after 'is'. 'Dr Rao is a surgeon' works; 'Dr Rao is proud of it' works. Grammarians say coordination can join items of different forms when they do the same job in the sentence. Compare 'The new goalkeeper is tall, quick and saves every penalty'. Now try each item after the shared words: 'is tall', 'is quick', 'is saves every penalty'. The last one breaks - it does not do the same job after 'is'. (Join the action to the whole verb phrase instead - 'is tall and quick, and saves every penalty' - and it is fine: that pairs two verb phrases.) So naming the shape is the first check, not the last. When labels differ, ask whether each item still does the same job after the shared words. If it does, leave it. If it does not, fix it. This chapter keys only the second kind as wrong.

Some -ing words are not -ing phrases at all. 'The hotel has a swimming pool, a games room and a library.' It is tempting to label 'a swimming pool' an -ing phrase and call the list a mismatch. But 'swimming' only tells you what kind of pool it is, the way 'games' tells you what kind of room. All three items are noun phrases - things the hotel has - and the list matches. Now compare 'The hotel is good for swimming, playing games and to read'. Here 'swimming' really is an activity, and 'to read' is the odd one out. The same letters, two different shapes. That is why you name the whole item, and why an ending alone - -ing, -ly, -ed - never decides the label.

This section names shapes; it does not ask you to name every part of speech inside an item. 'Noun phrase' covers a single noun ('rice') as well as a long one ('the rice my grandmother grows'). Items with different shapes can still be fine when they do the same job, as in 'a surgeon and proud of it'. Those are not keyed as errors anywhere in this chapter. How the items are punctuated - commas, and whether there is a comma before 'and' - is chapter 16's job. How 'and', 'or' and 'but' join clauses is chapter 10's.

  1. Find the joining words first: and, or, but, or the commas of a list.
  2. Box each item from one joining point to the next.
  3. Name the shape of the whole box, not its first word.
  4. Watch 'to': it starts both places ('to the bank') and actions ('to buy fruit').
  5. Watch -ing: 'swimming' can be an activity or just describe a pool.
  6. Compare the labels; the odd one is the item to mend.
  7. Mend the odd item to match the others - usually the easiest fix.
  8. If labels differ but every item does the same job, leave the sentence alone.
  9. Read the list aloud once more after the fix.
You can now name the shape of every item in a list. An item is one thing joined by and, or, but or the commas of a list. Its shape is the kind of phrase it is: a noun phrase (a map), an -ing phrase (reading comics), a to-phrase (to fly a kite), a verb phrase (won the race), an adjective (noisy), a prepositional phrase (in the park) or a clause (that the bus was late). You judge the whole item. The first word can mislead: 'to the bank' and 'to buy fruit' both start with 'to' but have different shapes, while 'in the park' and 'under the tree' start differently and match. When one label differs, that is the item to mend. And when labels differ but every item still does the same job - 'a surgeon and proud of it' - the sentence is fine as it is. Box it, label it, compare the labels.

-ing or to in a series

A series of actions has two tidy shapes, and 'to' has two tidy patterns. Every sentence in the left column is standard; the right column shows the two faults.

SteadyNot steady
I enjoy swimming, running and cycling.I enjoy swimming, running and to cycle. (-ing and to mixed)
I want to swim, run and cycle. ('to' once)I want to swim, run and to cycle. (half-repeat)
I want to swim, to run and to cycle. ('to' for all)I want to swim, running and cycling. (to and -ing mixed)

This is the Match Test on a series of actions: find the joint, name each item as -ing or to, and make every item match.

'To' once, or 'to' for all. Both are right. Half is the only fault.

Which form should the whole list take? Often the shared word decides. Some verbs take -ing, some take to, and some take either.

Shared wordTakesSteady series
enjoy, finish, keep, mind-ingShe enjoys sketching, painting and sculpting.
want, hope, plan, decide, needtoWe plan to camp, fish and hike.
like, love, start, prefereitherI love reading and writing. / I love to read and write.

So when you mend 'She enjoys sketching, painting and to sculpt', the fix has to be 'sculpting' - 'enjoys to sketch' is not English. When you mend 'We plan to camp, fishing and hiking', the fix has to be 'to camp, fish and hike'. With 'like' or 'love', either form works; pick one and keep it.

Why does repeating 'to' ever help? In a long series, a repeated 'to' marks where each new item starts. 'Our rules are to arrive by eight, to keep phones in bags until lunch and to leave the room tidy' is easier to follow than one 'to' stretched over three long items. In a short series, one 'to' is lighter. Both are choices; neither is a fault.

The shared verb picks the form. You pick whether 'to' repeats.

Picture a train. The engine is the shared verb - 'wants', 'enjoys'. The carriages are the items. An engine that runs on -ing tracks pulls only -ing carriages. A 'to' engine can pull one 'to' at the front for the whole train, or a small 'to' flag on every carriage. What it cannot do is fly a flag on some carriages and not others - then the passengers cannot tell which carriages belong together.

The shared 'to' only reaches as far as the list. In 'I want to swim, run and cycle, and my sister wants to paint', the first 'to' covers swim, run and cycle; the sister's list starts again with its own 'to'. So when you check a to-series, find where it starts and where it ends. A 'to' inside a new clause belongs to a new list, and a half-repeat can only happen inside one list.

Here is a sentence that looks like a half-repeat and is not. 'Ayaan wants to learn the guitar, join the band and to be ready for the concert by June.' Is that last 'to' a fault? Read the items. 'Learn the guitar' and 'join the band' are two steps. 'To be ready for the concert by June' may not be a third step at all - it may be the reason for the first two. If the writer means 'he wants to learn and join, in order to be ready', then the last part is a purpose, not an item, and the sentence reads better with the purpose moved out: 'To be ready for the concert by June, Ayaan wants to learn the guitar and join the band.' If the writer means three wants, then it is a half-repeat, and the fix is 'to learn the guitar, join the band and be ready'. So before you mend a to-series, ask whether every piece is really an item. The Match Test starts with finding the joint - and that means knowing which pieces the 'and' is joining.

Some verbs change their meaning between -ing and to - and a mixed list can hide the change. 'Remember to lock the door' means 'do not forget to do it'. 'I remember locking the door' means 'I have a memory of doing it'. So 'Please remember locking the door, switching off the fan and to feed the cat' is not only a mismatch - the first two items say the wrong thing. The fix is 'Please remember to lock the door, switch off the fan and feed the cat'. With 'stop', 'forget' and 'try' too, the form carries the meaning. Checking that a list keeps one form is also checking that every item means what you want.

This section is about keeping one form in a series. Which verbs take -ing and which take to is a large topic of its own; the table here names only common ones. Both 'to once' and 'to for all' are standard. Style guides differ on which reads better in long lists, and neither is ever keyed wrong in this chapter. Some verbs, like 'remember' and 'stop', change meaning between -ing and to; that is a meaning choice, not only a matching one. Commas in a series are chapter 16's job.

  1. Find the shared verb before the list: enjoy, want, like, hope.
  2. Ask which form it takes: -ing, to, or either.
  3. Put every item in that one form.
  4. With to, decide: once at the start, or before every item.
  5. Repeat 'to' when items are long, so each start is clear.
  6. Say 'to' once when items are short, so the list stays light.
  7. Mend a half-repeat by trimming the extra 'to' or adding the missing ones.
  8. Check that each piece is really an item and not a reason.
  9. Do not 'fix' a steady list just because it uses the other 'to' pattern.
  10. Read the list aloud with the shared verb before each item to hear any slip.
You can now keep a series in -ing or in to. A series of actions takes one form: 'swimming, running and cycling', or 'to swim, run and cycle'. Mixing them - 'swimming, running and to cycle' - is one of the commonest mismatches in school writing. The shared verb often decides the form: 'enjoy' takes -ing, 'want' takes to, and 'like' takes either. With to, there are two standard patterns. You can say 'to' once and let it cover every item, or say it before every item. The only fault is the half-repeat - 'to swim, run and to cycle' - where the pattern starts one way and changes. Mend it by trimming the stray 'to' or adding the missing ones. Long items often read better with 'to' repeated; short items with 'to' once. That is a style choice, not a rule. One form, one steady 'to'.

Phrases in a series

Two kinds of phrase make most real lists. The first words change from item to item; the shape does not.

Series ofEach itemSounds like
prepositional phraseson, in, under, past, before, after + a place or timeThe cat sleeps on the sofa, under the bed and in the basket.
prepositional phrases (time)before, after, at + a timeSana practises before breakfast, after school and at bedtime.
verb phrasesa doing word + what it acts onAppa washed the car, mowed the lawn and painted the gate.
broken seriestwo verb phrases, then a clauseAppa washed the car, mowed the lawn and the gate was painted.

This is the Match Test on phrases: find the joint, name each phrase's shape, and make the stray one match.

The first words may change. The shape may not.

The hardest phrase lists are the ones that change level. A verb phrase can hold a place phrase inside it - 'ran across the yard' - and a writer can slip from one level to the other.

SentenceItemsVerdict
The dog ran across the yard, over the fence and down the lane.three place phrases after one 'ran'matches
The dog ran across the yard, leapt the fence and raced down the lane.three verb phrasesmatches
The dog chased the cat, ate its dinner and into the garden.two verb phrases, then a place phrasebroken
Mira searched under the bed, behind the door and she even checked the fridge.two place phrases, then a clausebroken

So there are two ways to mend a broken phrase list. Either give the stray item a doing word so it joins the verb phrases ('and ran into the garden'), or turn it into a place phrase so it joins the others ('under the bed, behind the door and inside the fridge').

A quick check: say the shared start before each item. 'The dog chased the cat', 'the dog ate its dinner', 'the dog into the garden' - the last one has no verb, so it cannot stand in that list.

Keep every item on the same level: all where-phrases, or all doing-phrases.

Picture a staircase. Place phrases are steps on the lower flight; verb phrases are steps on the upper flight. You can walk a whole list along one flight - under the bed, behind the door, inside the fridge - or along the other - washed the car, mowed the lawn, painted the gate. A broken list is a step that suddenly drops to the other flight, and the reader stumbles.

A phrase list can share a start that is several words long. In 'Every evening, Sana sits by the window and practises the veena before dinner, after homework and at bedtime', the shared start is 'practises the veena', and the items are the three time phrases. When the shared start is long, find where it stops: the items begin right after it, and each one must fit on the end of it.

Here is a list that seems to break and does not. 'We looked for the kitten in the garden, under the car and behind the shed, then called the vet.' There are four pieces: 'in the garden', 'under the car', 'behind the shed', and 'called the vet'. The first three are place phrases; the fourth is a verb phrase. Is the list broken? No, because 'called the vet' is not an item in the place list. The place list belongs to 'looked for the kitten'. 'Then called the vet' joins a second action to 'looked'. So there are two lists at two levels: 'looked ... and called' (two verb phrases), and 'in the garden, under the car and behind the shed' (three place phrases inside the first one). The word 'then' is the clue that a new action is starting. Compare 'We looked in the garden, under the car and called the vet', where 'called the vet' is squeezed into the place list as if it were a third place. That one does break. So before you call a phrase list broken, find where each list begins and ends. The Match Test always starts with finding the joint.

The same words can make two different kinds of list. 'Nani walked to the temple, the market and the station.' Here 'to' is said once and shared: to the temple, to the market, to the station. The items are three noun phrases after one 'to'. 'Nani walked to the temple, past the market and round the station.' Here each item brings its own place word, so the items are three place phrases. Both lists match, in different ways. The first keeps one place word for all; the second changes the place word each time. What would break is mixing the two: 'to the temple, past the market and the station' leaves a reader unsure whether Nani went to the station or past it. S17 comes back to this choice.

This section groups phrases into two families: prepositional phrases (where or when) and verb phrases (what someone did). Grammar books name more kinds of phrase; you do not need them here. A verb phrase can contain a prepositional phrase ('ran across the yard'), so always find the items before labelling them. How a list of phrases is punctuated is chapter 16's job. Joining whole clauses with and, but or so is chapter 10's.

  1. Find the shared start of the list: 'The cat sleeps', 'Appa'.
  2. Box each item after it, from one joint to the next.
  3. Ask of each item: does it say where or when, or does it say what was done?
  4. Keep every item in that one family.
  5. Do not change a list just because the first words differ.
  6. Mend a stray clause by dropping its subject: 'and painted the gate'.
  7. Mend a stray place phrase in a verb list by giving it a doing word.
  8. Watch for a new action starting with 'then'; it may be a second list, not a broken one.
  9. Say the shared start before each item to check it fits.
You can now keep a series of phrases in one shape. Most real lists are made of phrases, not single words. Two kinds turn up again and again. Prepositional phrases say where or when: 'on the sofa, under the bed and in the basket', 'before breakfast, after school and at bedtime'. Verb phrases say what was done: 'washed the car, mowed the lawn and painted the gate'. The first words can change from item to item; the shape cannot. A list breaks when one item slips into another shape - a clause ('the gate was painted'), a place phrase in a list of actions ('into the garden'), or an -ing phrase ('and dancing'). Mend the stray item by turning it into the shape of the others, and check each one by saying the shared start before it. And before you call a list broken, check where it starts and ends: a 'then' may begin a second list. Same family, every item.

Clauses in a series

A clause has its own subject and its own verb. When a list's items are clauses, every item needs both.

Kind of clauseMatching series
whole statementsThe sky was grey, the wind was cold and the rain was falling.
that-clausesDadi said that the monsoon was late and that the wells were low.
because-clausesKiran stayed home because he had a cold and because it was raining.
who-clausesWe need a monitor who listens well and who keeps calm.
question-word clausesMum asked where we had been and why we were so muddy.

This is the Match Test on clauses: find the joint, check that each item is a clause, and give any stray item back its subject and verb.

A clause list is a list of small sentences. Each one needs a who and a does.

Clause lists break in three common ways. Each break turns one item into something smaller than a clause.

Broken seriesWhat the stray item becameMended
The shops were shut, the roads were icy and the empty streets.a noun phrase with no verband the streets were empty
We stayed in because it was raining and the cold.a noun phrase after 'because'and because it was cold
Nani is someone who tells great stories and never forgetting a birthday.an -ing phraseand never forgets a birthday

The last mend needs a second look. 'Who tells great stories and never forgets a birthday' has only one 'who' - and it matches. The one 'who' is shared by two verb phrases, just as one 'to' can be shared in a to-series. 'Who tells great stories and who never forgets a birthday' is standard too. What breaks the pattern is an -ing phrase that cannot follow 'who'.

A quick check for each item: put it on its own and ask 'Is this a small sentence?' 'The roads were icy' - yes. 'The empty streets' - no, it has no verb. If the other items pass and one fails, that is the item to mend.

Give the stray item back what it lost - usually a verb, sometimes a subject too.

Picture a row of small houses on a street. Every house has a door (the subject) and a roof (the verb). You can walk down the street and knock on each one: the sky - was grey; the wind - was cold; the rain - was falling. A broken clause list has one house with no roof - 'an empty beach' - and the whole street looks unfinished until you build it: 'the beach was empty'.

A clause can hold a list inside it, and the inner list follows its own rules. In 'Dadi said that the monsoon was late, the wells were low and the fields were dry', 'that' is said once and covers three statements. In 'Dadi said that the monsoon was late, that the wells were low and that the fields were dry', 'that' is said for every item. Both are standard; only the half-repeat ('that ... , the wells ... and that ...') is the wobble you met with 'to' in S12. S17 returns to this for all the little words.

Here is a sentence where one little word changes what the list means. 'Riya said that the shop was shut and we went home.' How many things did Riya say? The sentence can be read two ways. Riya may have said one thing - the shop was shut - and then we went home. Or she may have said two things: the shop was shut, and we went home. Now add a second 'that'. 'Riya said that the shop was shut and that we went home.' The ambiguity is gone. The second 'that' shows that 'we went home' is also part of what Riya said. Both clauses are items in one list after 'said'. And if you meant the other reading - Riya said one thing, then we went home - you can make that clear too: 'Riya said that the shop was shut, so we went home.' Now 'so' joins a new clause that is not part of what she said. This is why repeating 'that' is sometimes more than style. When a that-list could be misread, a repeated 'that' marks each clause as an item in the same list. When the meaning is already clear, 'that' said once is enough.

Some of the most famous short sentences are lists of clauses. Julius Caesar is reported to have summed up a quick victory in three Latin words, usually translated into English as 'I came, I saw, I conquered.' Look at the shape: three items, and each one is a whole clause with its own subject and verb - I came; I saw; I conquered. Nothing is added, nothing is dropped, and the sentence is remembered two thousand years later. Now break it: 'I came, I saw and a victory.' The third item is a noun phrase, and the whole sentence falls flat. Matching clauses are not only correct; they are memorable. Craft will look at why a rhythm of three clauses sticks in the mind.

This section is about keeping every item in a clause list a clause. It does not teach how clauses are joined with and, but, so or because - that is chapter 10's job. 'That', 'who' and 'because' said once for all items or repeated for each are both standard; this chapter never keys either as wrong. Some items of different forms can do the same job, as in 'because it was late and because of the rain'; those are not keyed as errors either. Commas between clauses are chapter 16's job.

  1. Find the joint and the items after it.
  2. For each item, underline the subject once and the verb twice.
  3. If every item has both, the clause list matches.
  4. If one item has no verb, give it one: 'the streets were empty'.
  5. If one item is a noun phrase, turn it into a clause: 'because it was cold'.
  6. After 'who' or 'that' said once, each item needs a verb that fits it.
  7. Repeat 'that' when a that-list could be misread.
  8. Say 'that' once when the meaning is already clear.
  9. Read each item alone as a small sentence to check it.
  10. Leave a same-job pair of different forms alone when each part still fits.
You can now keep a series of clauses whole. A clause has its own subject and its own verb. Lists of clauses are everywhere: statements ('the sky was grey, the wind was cold and the rain was falling'), that-clauses ('said that ... and that ...'), because-clauses, who-clauses and question-word clauses ('where we had been and why we were so muddy'). When the items are clauses, every item must be a clause. A list breaks when one item loses its verb ('and the empty streets'), becomes a noun phrase ('and the cold'), or slips into -ing ('and never forgetting a birthday'). Mend it by giving the item back its subject and verb. 'That' and 'who' can be said once or repeated for each item; both are standard. Repeat 'that' when a list could be misread, as in 'Riya said that the shop was shut and that we went home'. Every item, a who and a does.

Either-or, both-and, not only-but also

Correlatives come in pairs. Each word of the pair points at the item that follows it, and the two items should share a shape.

PairMatching itemsShape
both ... andMeena both sings and dances.verb phrase + verb phrase
either ... orEither you call or you write.clause + clause
neither ... norEmma wants neither cake nor ice cream.noun phrase + noun phrase
not only ... but alsoRaj plays not only the sitar but also the tabla.noun phrase + noun phrase
whether ... orWhether George walks or cycles, he wears a helmet.verb phrase + verb phrase

This is the Match Test on a pair: the pair words mark the joint, so name the item after each one and make them match.

What follows the first word should match what follows the second.

There are two ways a pair can go wrong, and they are not equally serious.

SentenceAfter word oneAfter word twoVerdict
Aditi hopes either to sing or dancing.to-phrase-ing phrasea mismatch - fix it
Riya is both a fast runner and swims well.noun phraseverb phrasea mismatch - fix it
Mira not only plays the sitar but also the tabla.verb phrasenoun phraseloose placement - common in speech
Mira plays not only the sitar but also the tabla.noun phrasenoun phrasetight - the formal choice

A mismatch puts two different kinds of item after the pair words, and the sentence breaks: 'Riya is ... swims well' does not work. Mend it by changing one item: 'both a fast runner and a strong swimmer'.

Loose placement is different. 'Mira not only plays the sitar but also the tabla' is clear, and people say it all the time. The pair words are just a step away from their items. In careful, formal writing - a report, an application, an exam answer - move the first word to sit right before its item: 'plays not only the sitar but also the tabla'. In a chat with a friend, leave it.

A mismatch is a fault. Loose placement is a register choice: tighten it for formal writing.

Picture a see-saw in a playground. The first pair word sits at one end, the second at the other, and each carries one item. Put two children of the same size on it - 'the sitar' and 'the tabla' - and it balances. Put a child on one end and a bicycle on the other - 'sings' and 'a dancer' - and it crashes. Loose placement is like one child sitting a little way along the plank: it still works, but in a formal photo you would ask them to shuffle to the end.

The second word of a pair is fixed - 'or', 'nor', 'and', 'but also' - so the first word is usually the one to move. When a pair does not match, look at what follows the second word first, then slide the first word until it sits in front of an item of the same shape. 'Mira not only plays the sitar but also the tabla': 'but also' is followed by 'the tabla', so 'not only' slides to sit in front of 'the sitar'.

Here is a pair where both placements are fine, and they mean slightly different things. 'Either Kofi will take the bus or he will ride his bike.' 'Kofi will either take the bus or ride his bike.' In the first, 'either' and 'or' point at two whole clauses: 'Kofi will take the bus' and 'he will ride his bike'. In the second, they point at two verb phrases: 'take the bus' and 'ride his bike'. Both pairs match. The first makes the choice feel like two separate possibilities; the second is lighter and keeps Kofi as one subject. Now look at the mixed version: 'Either Kofi will take the bus or ride his bike.' 'Either' points at a clause and 'or' at a verb phrase. It is very common in speech, and every listener understands it. In formal writing, careful writers move 'either' so both sides match. So the choice is not only right against wrong. It is often clause against phrase - which size of item you want to put on the see-saw. Pick one size and put it on both ends.

'Both' can only point at two items, but 'either' and 'neither' sometimes stretch. 'You can pay either by cash, by card or by cheque.' 'Either' points at three items here, and many writers do this. Some style guides prefer to keep 'either' for exactly two and would write 'You can pay by cash, by card or by cheque'. Both are understood, and you will see both in print. What stays the same is the matching: 'by cash, by card, by cheque' are three prepositional phrases. 'Either by cash, with a card or a cheque' would jar - not because 'either' has three items, but because the shapes wobble. The number of items is a style question. The matching is not.

This section is about matching the items after correlative pairs. How 'either ... or' and 'neither ... nor' affect the verb ('Neither Ravi nor his sisters are home') is chapter 12's job. Loose placement ('She not only plays the sitar but also the tabla') is common and clear in speech. This chapter keys the tight placement only when a question asks for formal or written English. Items of different forms that do the same job can still be fine. Placing correlatives for emphasis is taught further in Craft.

  1. Find the pair: either/or, neither/nor, both/and, not only/but also, whether/or.
  2. Read the item after the second word first.
  3. Check that the item after the first word has the same shape.
  4. If the shapes differ, change one item so they match.
  5. In formal writing, slide the first word to sit right before its item.
  6. In speech, loose placement is normal; do not correct a friend for it.
  7. Choose clause and clause, or phrase and phrase - one size on both ends.
  8. Keep 'both' for two items; use 'either' for more only if your style allows it.
  9. Read the pair aloud as a see-saw: this ... and that.
You can now put matching items after both words of a pair. Correlatives are joining words that come in pairs: either ... or, neither ... nor, both ... and, not only ... but also, whether ... or. Each word points at the item that follows it, and the two items should share a shape: 'both sings and dances', 'not only the sitar but also the tabla', 'either you call or you write'. A mismatch puts different shapes after the two words - 'either to sing or dancing', 'both a fast runner and swims well' - and needs mending. Loose placement is different: 'She not only plays the sitar but also the tabla' is clear and very common in speech. In formal writing, slide the first word so it sits right before its item: 'plays not only the sitar but also the tabla'. What follows the first word should match what follows the second.

Comparisons with than and as

'Than' and 'as ... as' join two items. The items should match in two ways: in shape, and in kind.

BalancedUnbalancedWhat is off
Swimming is better than running.Swimming is better than to run.shape: -ing against to
It is easier to walk than to wait for the bus.It is easier to walk than waiting for the bus.shape: to against -ing
The weather in Delhi is hotter than that in Shimla.The weather in Delhi is hotter than Shimla.kind: weather against a city
Priya's marks are higher than Ravi's.Priya's marks are higher than Ravi.kind: marks against a boy

This is the Match Test on a comparison: 'than' and 'as' mark the joint, so name both sides and make them match.

Weigh apples against apples. 'Than' and 'as' are the scales.

When the second side is the same kind of thing as the first, English has neat ways to avoid saying it twice.

ToolStands forExample
a possessivethe same thing, belonging to someone elseMeera's handwriting is neater than her brother's.
that of / that inone thing already namedThe population of Mumbai is larger than that of Pune.
those of / those inmore than one thing already namedThe roads in Mumbai are busier than those in Pune.
one / onesa countable thing already namedThe blue box is as heavy as the red one.

'That' is for one thing, 'those' for more than one: 'the population ... that of Pune', 'the roads ... those in Pune'. A possessive is often simplest: 'Priya's marks are higher than Ravi's' - the word 'marks' is understood after 'Ravi's'.

How serious is 'hotter than Shimla'? In speech, it is so common that nobody is confused. In careful writing - a geography answer, a report - readers expect like with like, and the two little words 'that in' cost nothing. The shape mismatch ('better than to run') is different: it jars in speech too.

One thing: 'that of'. More than one: 'those of'. Or a possessive: 'Ravi's'.

Picture a kitchen scale with two pans. 'Than' or 'as' is the pointer in the middle. You can weigh a bag of rice against a bag of rice - the weather in Delhi against the weather in Shimla. You cannot sensibly weigh a bag of rice against a whole shop - the weather in Delhi against Shimla. And the two bags should be the same kind of bag: an -ing bag on each pan, or a to bag on each pan.

'As ... as' works just like 'than'. The first 'as' sits before the describing word, and the second 'as' joins the two items: 'Reading is as much fun as drawing.' The two items are 'reading' and 'drawing', so they should match: 'as much fun as to draw' would wobble. When you check an as-comparison, skip the describing word in the middle and look at the two ends.

Here is a comparison where the two sides look unlike and are fine. 'Priya runs faster than Ravi.' Priya is a person; Ravi is a person. What is being compared is how fast each one runs, and the sentence says 'Priya runs faster than Ravi [runs]'. The verb is understood on the second side. Like with like. Now compare 'Priya's speed is greater than Ravi.' Here the first side is 'Priya's speed', a thing, and the second side is Ravi, a person. Unlike. The fix is 'greater than Ravi's'. So you cannot judge a comparison by whether the second side is a name. You have to find what the first side really is. If it is a person doing something, a person on the other side is right. If it is a thing belonging to a person - speed, marks, handwriting, weather - the other side needs the same thing: 'Ravi's', 'that of Ravi', 'that in Shimla'. The Match Test question is always the same: what is on the left pan? Put the same kind of thing on the right.

Some comparisons with unlike things are famous on purpose. Poets and advertisers compare a voice with a bird, or a smile with the sun: 'Her voice is as sweet as a nightingale.' Read word for word, it weighs a voice against a whole bird. Nobody minds, because the reader knows it is a picture, not a measurement. In a science report, the same move would be a mistake. 'The boiling point of water is higher than alcohol' should be 'higher than that of alcohol', because a report measures things, and the reader needs to know exactly what was measured. So like-with-like is a rule of careful, factual writing. Figurative comparisons, which chapter 26 studies, play by looser rules - and still keep the shape: 'as sweet as a nightingale' is adjective, then noun phrase, in a steady frame.

This section is about matching the two sides of a comparison. How to form comparatives ('bigger', 'more careful') is chapter 3's job. Comparisons of unlike things ('hotter than Shimla') are common and clear in speech; this chapter keys the like-with-like version only where a question asks what is compared or asks for careful writing. Whether to write 'taller than me' or 'taller than I' is a pronoun question, not a parallel one. Figurative comparisons ('as sweet as a nightingale') are studied in chapter 26.

  1. Find 'than' or 'as ... as' and the two items it joins.
  2. Check the shape: -ing with -ing, to with to, noun phrase with noun phrase.
  3. Check the kind: is the second side the same sort of thing as the first?
  4. If the first side is a thing belonging to someone, add a possessive: 'Ravi's'.
  5. Use 'that of' or 'that in' for one thing, 'those of' or 'those in' for more than one.
  6. Use 'one' or 'ones' for countable things: 'the red one'.
  7. If the first side is a person doing something, a person on the other side is fine.
  8. In speech, do not fuss over 'hotter than Shimla'; in a report, write 'that in Shimla'.
  9. Read the comparison as two pans on a scale.
You can now compare like with like. 'Than' and 'as ... as' join two items, just as 'and' does, and the items should match in two ways. In shape: 'Swimming is better than running' balances -ing with -ing, and 'It is easier to walk than to wait' balances to with to. 'Swimming is better than to run' wobbles. In kind: the two sides should be the same sort of thing. 'The weather in Delhi is hotter than Shimla' is clear in speech but weighs weather against a city; careful writing says 'than that in Shimla'. 'Priya's marks are higher than Ravi's' weighs marks against marks. The tools are small: a possessive ('Ravi's'), 'that of' for one thing, 'those of' for more, 'one' for a countable thing. And when the first side is a person doing something - 'Priya runs faster than Ravi' - a person on the other side is already right. Apples against apples.

Repeat or say once

A little word before a list can be said once and shared, or said before every item. Both are standard. The half-repeat is the only pattern that wobbles.

Little wordSaid onceSaid for allHalf-repeat
inin the morning, the afternoon and the eveningin the morning, in the afternoon and in the eveningin the morning, the afternoon and in the evening
aa pen, pencil and rulera pen, a pencil and a rulera pen, a pencil and ruler

thatsaid that it rained, the roads flooded and the bus was latesaid that it rained, that the roads flooded and that the bus was latesaid that it rained, the roads flooded and that the bus was late

This is the Match Test on little words: at the joint, each item either shares the little word or carries its own - all of them the same way.

Once, or for all. Both are right. Half is the only wobble.

Sometimes the choice is not free. A shared little word has to fit every item it covers - so read each item with it.

ListRead each item with the shared wordChoice
an apple, banana and orangean apple, an banana, an orangemust repeat: an apple, a banana and an orange
in May, June and Julyin May, in June, in Julyonce or for all - free
at home and schoolat home, at schoolonce works; 'at home and at school' also fine
interested in and good at mathsinterested in maths, good at mathsshared 'maths' fits both (S18)

Repeating can also carry meaning. 'Rekha met the author and illustrator' most naturally means one person who did both jobs. 'Rekha met the author and the illustrator' means two people. The second 'the' says 'a second person'.

And repeating can help the reader in a long list. 'The rules say that phones stay in bags, that shoes come off at the door and that lunch is eaten in the hall' is easier to follow than one 'that' stretched over three long clauses. When the items are short, one little word keeps the list light.

A shared word must fit every item. When it would not - or would change the meaning - repeat it.

Picture a row of children at a school gate with one umbrella. If the umbrella is big enough, one child can hold it over everyone - the little word said once. Or every child can carry a small umbrella of their own - the little word said for all. What looks odd is two children with umbrellas and one getting wet in the middle. And if one child needs a different colour of umbrella - 'a' among 'an's - that child must carry their own.

The pattern applies inside each list separately. In 'We went to the market and the temple, then to the park and the lake', there are two lists, each with 'to' said once and 'the' said for every item. Each list is steady on its own. When you check a long sentence, find where each list begins and ends, and look at its little words on their own - a new list can make a fresh choice.

Here is a sentence where one 'the' decides how many people there are. 'The captain and coach gave a speech.' 'The captain and the coach gave a speech.' In the first, one 'the' is shared by 'captain' and 'coach'. The most natural reading is one person who is both captain and coach. In the second, each noun has its own 'the', so there are two people. This is the umbrella again. One umbrella over two names can mean they are one person. Two umbrellas mean two people. The verb can help too: 'The captain and coach is giving a speech' makes one person certain; 'are giving' leans towards two. Chapter 12 looks at that side of it. Most of the time, once and for all mean the same thing, and the choice is style. But when a shared 'the' or 'a' could join two names into one person, repeating the little word is the clear choice. So when you decide between once and all, ask: will the reader count the items the way I mean?

A single missing 'that' can change who said what. 'The teacher said that the test was hard, the marks were low and we should practise more.' With 'that' said once, the natural reading is that all three clauses are what the teacher said. Now remove the only 'that': 'The teacher said the test was hard, the marks were low and we should practise more.' Still read as all reported - English often leaves 'that' out entirely. Now try a half-repeat: 'The teacher said that the test was hard, the marks were low and that we should practise more.' Readers start to wonder whether the middle clause is something the teacher said or a fact the writer is adding. The wobble is not only in the sound; it blurs who is speaking. The little words are small, but they mark where each item begins - and whose item it is.

Both 'said once' and 'said for all' are standard, and this chapter never keys either as wrong. Only the half-repeat is keyed. Articles also carry meaning: dropping 'the' before a plural ('we took the mats, the flask and sandwiches') can mean 'some sandwiches', which is not a half-repeat. Items here use singular nouns or clear lists. When to use a, an or the at all is chapter 5's job. How 'and' agrees with a verb when two names might be one person is chapter 12's.

  1. Find the little word before the list: a, an, the, to, in, on, at, that.
  2. Count the items and count the little words.
  3. One little word for all, or one for each item - both are fine.
  4. If the count is in between, mend the half-repeat either way.
  5. Read each item with a shared word; if it does not fit, repeat the word.
  6. Repeat 'the' or 'a' when you mean two different people or things.
  7. Repeat 'that' or 'to' when the items are long, to mark each start.
  8. Say the word once when the items are short, to keep the list light.
  9. Do not 'fix' a list that already uses once or all.
You can now repeat a little word or say it once - and avoid the half. Little words like a, an, the, to, in, on, at and that often stand before a list. You can say the little word once and let every item share it - 'in the morning, the afternoon and the evening' - or say it before every item - 'in the morning, in the afternoon and in the evening'. Both are standard. The half-repeat - 'in the morning, the afternoon and in the evening' - is the one pattern that wobbles, and you can mend it by trimming or completing. Sometimes the choice is not free. A shared word must fit every item, so 'an apple, a banana and an orange' repeats because 'banana' needs 'a'. And a shared 'the' can join two names into one person, so 'the author and the illustrator' repeats to show two people. Repeat for long items, share for short ones. Once, or for all.

The drop test

When items share words, each item must fit those words on its own. The drop test checks it: read each item alone with the shared words.

SentenceDrop testResult
Ishita is interested in and good at maths.interested in maths / good at mathsboth fit
Tanya is fond and interested in birds.fond in birds / interested in birds'fond' needs 'of'
Arjun has always and will always love cricket.has always love cricket / will always love cricket'has' needs 'loved'
Rohan relied on and trusted his teacher.relied on his teacher / trusted his teacherboth fit

This is step three of the Match Test: read each item on its own after the shared words, and make sure it still fits.

Shared words must fit every item. The drop test finds the one that does not.

The drop test finds three kinds of gap. Each has a quick mend.

GapBrokenMended
a missing little wordTanya is fond and interested in birds.fond of and interested in birds
a wrong verb formArjun has always and will always love cricket.has always loved and will always love cricket
a half-built comparisonHarry is as tall or taller than his dad.as tall as or taller than his dad

The comparison needs a closer look. 'As tall or taller than his dad' shares 'his dad'. Drop in each item: 'taller than his dad' works, but 'as tall his dad' does not - it needs its own 'as'. This one is very common in speech, and listeners rarely mind. In careful writing, add the missing 'as', or move the second item to the end: 'as tall as his dad, or taller'.

Some shared words pass easily. 'Freya was fond and proud of her brother' shares 'of her brother': 'fond of her brother', 'proud of her brother'. Both fit, because both words take 'of'. So the drop test does not mean 'always write both little words' - it means 'check whether one serves both'.

One little word can serve two items - if it is the word each one needs.

Picture a charging lead with one plug at the end and two phones attached by short cables. The plug is the shared words - 'in birds', 'love cricket'. Every phone must fit the plug. If one phone has a different socket - 'fond' needs 'of', not 'in' - it will not charge, however neat the lead looks. The drop test is unplugging each phone and trying it alone.

The shared words can come at the start as well as the end. In 'The film was exciting, funny and moving', the shared start is 'The film was', and each item must fit after it: 'The film was exciting', 'The film was funny', 'The film was moving'. In 'interested in and good at maths', the shared end is 'maths'. Many sentences share both a start and an end - 'Ishita is ... maths' - so check both sides of each item.

Here is a sentence that passes one drop test and fails another. 'Ana is taller and as fast as her cousin.' The shared start is 'Ana is'. 'Ana is taller' works. 'Ana is as fast' works. So the start is fine. The shared end is 'her cousin'. 'As fast as her cousin' works. 'Taller her cousin' does not - it needs 'than'. So the end fails. The mend is to give 'taller' its own 'than': 'Ana is taller than and as fast as her cousin.' Now both drop tests pass. Some writers find two little words in a row - 'than and as' - a bit heavy, and move one item instead: 'Ana is as fast as her cousin, and taller.' This is why the drop test always has two halves. You check each item after the shared start and before the shared end. A sentence that passes one half can still fail the other, and the fault is usually hiding at the end, where the eye moves fastest.

The drop test catches a mistake that even careful speakers make in speeches and interviews. 'We have and we will continue to support our players.' It sounds strong. Drop in each item: 'We will continue to support our players' - fine. 'We have continue to support our players' - broken. The speaker meant 'We have supported and will continue to support our players'. In speech, listeners fill the gap without noticing, because the meaning is clear and the rhythm is good. On the page, the gap shows. That is a useful thing to know about any sentence: the drop test is harder on writing than on speech, because a reader can stop and read each item again. None of this means the speaker was careless. It means that shared words are a spoken habit that writing checks more closely.

This section checks that items fit the words they share. Which little word goes with which adjective or verb - 'fond of', 'interested in', 'rely on' - is chapter 7's job; here you only need to hear when one is missing. Half-built comparisons ('as tall or taller than') are common and clear in speech; this chapter keys the completed version only for careful or formal writing. When one little word does fit every item ('fond and proud of'), sharing it is standard and never keyed wrong.

  1. Find the words the items share - at the start, at the end, or both.
  2. Cover all the items but one, and read that item with the shared words.
  3. Do the same for every item.
  4. If a version breaks, give that item its own words.
  5. Check little words: fond of, interested in, rely on, good at.
  6. Check verb forms: has loved, will love; can help, has helped.
  7. Check comparisons: as ... as, and ... than.
  8. If one little word serves every item, sharing it is fine.
  9. If two little words in a row feel heavy, move one item to the end.
  10. Read the whole sentence once more after the mend.
You can now run the drop test. When items share words - 'interested in and good at maths' - each item must fit those words on its own. The drop test checks it: cover the other items, read one item with the shared words, and do it for every item. The test finds three kinds of gap. A missing little word: 'fond and interested in birds' needs 'fond of'. A wrong verb form: 'has always and will always love' needs 'has always loved'. A half-built comparison: 'as tall or taller than his dad' needs 'as tall as' in careful writing. The test also clears sentences that are already right. 'Fond and proud of her brother' passes, because both take 'of' - no extra word needed. Check both sides: the shared start and the shared end. Shared words must fit every item.

Headings and bullet lists

A column of bullets or headings is a list with no 'and' to hold it together. The shape of each line does all the work, so every line starts the same way.

PatternMatching linesGood for
commandsPlan the route / Book the tickets / Pack the bagssteps, checklists, rules
-ing phrasesGetting started / Choosing a bike / Staying safechapter and section headings
noun phrasesAim / Method / Results / Conclusionreport headings, labels
question-word clausesWhy we need sleep / How much we need / What happens without itslides, posters

This is the Match Test on a column: each line break is a joint, so name each line's shape and make them match.

No 'and', no commas - just the shape. So the shape has to match.

Many bullet lists hang from a lead-in line that ends with a colon. Every bullet must finish that line - which is the drop test from S18, done downwards.

Lead-inBulletRead together
At camp you will:learn to swimAt camp you will learn to swim. ✓
build a raftAt camp you will build a raft. ✓
campfire cookingAt camp you will campfire cooking. ✗
Before the test, please:switch off your phoneBefore the test, please switch off your phone. ✓
phones switched offBefore the test, please phones switched off. ✗

The mend is to rewrite the stray bullet so it finishes the lead-in: 'cook on a campfire'. Or change the lead-in so every bullet fits it: 'Camp activities:' followed by 'Swimming / Raft building / Campfire cooking'.

Headings without a lead-in still need to match each other. 'Causes of floods / Effects of floods / Preventing floods' has two noun phrases and an -ing phrase. 'Prevention of floods' matches. Nothing is ungrammatical in the mixed set - it just reads less like a set.

Read the lead-in before every bullet. Each one must finish it.

Picture the handles on a row of kitchen drawers. When every handle is the same, you can see at once that the drawers belong together and your hand finds each one without looking. One odd handle - a knob among bars - makes you stop and check whether that drawer is part of the set. Bullets and headings are the handles of a page: the first words are what the reader's eye grabs.

Bullets can be long, and the rule still holds. 'Collect the bottles from every classroom on Monday' and 'Wash them' are both commands, though one is much longer. What must match is the start of each line - the part the eye catches first. Once the starts match, each line can carry as much detail as it needs after that, and a short line and a long line sit happily side by side.

Here is a set where every line is fine, and the set still fails. A project poster has the heading 'How we tested it' and these bullets: We filled three pots with soil. Planting a bean in each pot. Pot A was kept in the dark. Water every day. Each line makes sense on its own. But look at the starts: a sentence with 'We', an -ing phrase, a sentence with 'Pot A' and a command. Four lines, four shapes. A reader cannot tell whether these are things that happened, things to do, or notes. Choose one pattern and apply it to every line. As things that happened: 'We filled three pots with soil. We planted a bean in each pot. We kept Pot A in the dark. We watered every pot daily.' As instructions for someone else: 'Fill three pots with soil. Plant a bean in each pot. Keep Pot A in the dark. Water every pot daily.' The pattern should suit the job. A report of what you did takes sentences in the past; a method for others to follow takes commands. Chapter 13's anchor idea helps here - pick the time and the shape once, and keep them for every line.

Some of the most carefully matched lists you read every day are road signs and notices. 'Stop. Look. Listen.' Three one-word commands. 'No parking. No entry. No U-turn.' Three noun phrases, each starting with 'No'. Sign-makers have only a second of the driver's attention, so they cannot afford a line that breaks the pattern. A sign that said 'Stop. Looking. You should listen.' would slow every driver down while they worked it out. The same is true of a slide in class, a menu on a wall, or a checklist on a fridge. When people read on the move, matching shapes are not decoration - they are what makes the list readable at all.

This section is about matching the lines of a set of bullets or headings. Whether bullets take full stops, capital letters or commas is a layout and punctuation choice (chapter 16), and styles differ between schools and publishers. A mixed set of headings is not ungrammatical; it is harder to scan. This chapter keys the matching version as the better set, not the mixed one as a grammar error. CVs and job applications, where matching bullets matter a great deal, are studied in Craft.

  1. Treat every set of bullets or headings as a list.
  2. Pick one pattern: commands, -ing phrases, noun phrases or questions.
  3. Write the first word of each line in a column and check they match.
  4. Use commands for steps, checklists and rules.
  5. Use noun phrases or -ing phrases for headings.
  6. If there is a lead-in with a colon, read it before every bullet.
  7. Rewrite a stray bullet so it finishes the lead-in, or change the lead-in.
  8. Let lines be long or short - only the starts must match.
  9. Match the time too: all past for what you did, all commands for what to do.
You can now make headings and bullet points match. A set of bullets or headings is a list with no 'and' and no commas to hold it together. The shape of each line does all the work, so every line should start the same way. Commands suit steps and checklists ('Plan the route / Book the tickets / Pack the bags'). Noun phrases and -ing phrases suit headings ('Aim / Method / Results', 'Getting started / Choosing a bike / Staying safe'). Questions suit slides and posters. When bullets hang from a lead-in line, each bullet must finish it - the drop test done downwards. 'At camp you will: learn to swim / build a raft / campfire cooking' breaks at the last line. The first words are the handles of the page. Make them match, and the reader can scan the whole list at a glance. One pattern, every line.

Explain your evidence

Every Practice choice has a reason you can say in one sentence: the joint, the shapes, and the fix - or 'both are standard'.

SectionThe reason sounds like
S11 naming the shape'To the bank' is a place; 'to buy fruit' is an action.
S12 -ing or toTwo -ing phrases and a to-phrase: make it 'swimming'.
S13 phrasesTwo verb phrases and a clause: 'and painted the gate'.
S14 clauses'The empty streets' has no verb: 'the streets were empty'.
S15 pairs'Either' points at a to-phrase, 'or' at -ing: 'or to dance'.
S16 comparisonsWeather against a town: 'than that in Shimla'.
S17 repeat or once'To' once or for all is standard; half is not.
S18 drop test'Fond in birds' fails: 'fond of'.
S19 bulletsThree commands and an -ing line: 'Paint them'.

Every row is the Match Test said aloud: find the joint, name each item's shape, then make them match - or show that they already do.

A reason names what decides. A guess names what sounds right.

The hardest reasons to give are the ones that say 'leave it alone'. They need evidence too.

SentenceTempting 'fix'The reason to leave it
Ishaan hopes to win, to thank his coach and to celebrate.drop two 'to's'To' for every item is as standard as 'to' once (S12, S17).
Dr Rao is a surgeon and proud of it.make both items adjectivesDifferent forms, same job: both describe Dr Rao after 'is' (S11).
Freya is fond and proud of her brother.add a second 'of'Both words take 'of', so one 'of' passes the drop test (S18).
'I not only play the sitar but also the tabla,' Mira tells a friend.move 'not only'Loose placement is common and clear in speech (S15).
Priya runs faster than Ravi.'than Ravi's'A runner is compared with a runner (S16).

Notice the shape of each reason. It does not say 'it sounds fine'. It names the pattern - to for all, same job, one shared 'of', speech, runner with runner - and that pattern is something anyone can check.

A good reason also fits its context. Mira's sentence is fine in a chat; the same sentence in a formal report might be tightened, and the reason would change to 'formal writing places "not only" right before its item'.

'Standard as it is' is an answer - but only with a reason attached.

Picture a referee at a match. A good referee does not just blow the whistle; they point at the spot and show the signal - offside, foul, handball - so both teams can see why. A reason is your signal. 'Two -ing phrases and a to-phrase' points at the spot. 'Play on - both are standard' is a signal too. A whistle with no signal is a guess, however confident it sounds.

A strong reason usually has three parts, and you can say them in one breath: 'The joint is "and"; two items are -ing phrases and one is a to-phrase; so "to swim" becomes "swimming".' When you are short of time, keep the middle part - the shapes - because it is the evidence. 'Two -ing, one to' already tells a reader where the fault is and what the fix must be.

Here is a sentence where two different fixes are both correct - and the reason has to say which one you chose and why. 'Rohan wants to paint, draw and to sculpt.' One fix trims the last 'to': 'to paint, draw and sculpt'. The other adds a 'to': 'to paint, to draw and to sculpt'. Both are standard, and both mend the half-repeat. So a reason that says 'You must remove the last "to"' is too strong; the other fix is just as right. A good reason names the fault and then the choice: 'The half-repeat gives "to" to two items out of three; I said it once, because the items are short.' Or: '...; I repeated it, to match the rest of the list in my essay.' The same is true of many Practice fixes. 'Plan the route / Booking tickets / The bags' can become three commands or three noun phrases. 'Either to sing or dancing' can become 'either to sing or to dance' or 'either singing or dancing'. When more than one fix works, the evidence is the fault, and the choice is yours. Say both: what was wrong, and why you picked your mend.

Sometimes the best reason is that nothing needs fixing, even when the sentence looks unusual. 'He is a doctor and proud of it.' Many learners are taught that joined items must be the same form, so they reach for a fix: 'a doctor and a proud man'? 'medical and proud'? Each rewrite is clumsier than the original. The reason to leave it alone is precise: 'Both items describe him after "is" - "is a doctor", "is proud of it" - so they do the same job, and English accepts that.' That sentence names the joint, names the shapes, and gives the evidence for 'standard'. The surprise is that knowing parallel structure well makes you change fewer sentences, not more. The rule you carry at the end of Practice is not 'make everything the same' but 'make the items fit their joint - and prove it'.

This section asks for reasons, not new rules. Every reason here comes from S11-S19. Some choices have two correct fixes, and some sentences need no fix; a good reason says which. Where speech and careful writing differ - loose correlatives, unlike comparisons, half-built comparisons - the reason should name the context. Commas in a list are chapter 16's job, and how clauses are joined is chapter 10's; neither is a reason here.

  1. Start by naming the joint: and, or, a pair, than, as, a list or a column.
  2. Name the shape of every item.
  3. Say which item does not match - or that they all do.
  4. Say the fix in a few words.
  5. If two fixes work, name the fault and then your choice.
  6. If both versions are standard, say so and say why.
  7. Name the context when speech and careful writing differ.
  8. Use the drop test as evidence: 'fond in birds' fails.
  9. Avoid 'it sounds better' and 'never' or 'always' rules.
  10. Keep your reason to one sentence, so it can be checked quickly.
  11. Check your own reason against the sentence before you write it down.
You can now explain your evidence for any Practice choice. A good reason is the Match Test said aloud, in one sentence. Name the joint - and, or, a pair, than, as, a list or a column of bullets. Name each item's shape - noun phrase, -ing phrase, to-phrase, verb phrase, adjective, prepositional phrase or clause. Then say the fix: make the odd item match, give it back its verb, add its little word, or compare like with like. Some reasons end with 'both are standard': 'to' once or for all, a doctor and proud of it, one shared 'of' that fits both words, loose placement in speech. Those need evidence too - the pattern that makes them standard. When two fixes work, name the fault and then your choice. When speech and careful writing differ, name the context. A reason names what decides. A guess names what sounds right.

Faults in long sentences

The Match Test works at any length. What changes in a long sentence is that step two - naming each item's shape - has to be done on purpose, because the ear stops helping.

What hides the faultExampleWhere to look
a long middle itemto build a model, to collect readings from the roof for three weeks, and presenting the resultsthe first word of the item after the long one
a long gap after the jointShe told us that the bus was late, that the driver had lost his way, and about the flat tyrethe word that opens each item
a long subject before the verbsThe students who had signed up for the trip packed, labelled and were checking their bagsevery verb that shares the subject

The trick in every row is the same: strip each item down to its first word or two and line them up. 'to build / to collect / presenting' shows the fault at once.

Distance hides a fault in three different ways, and each needs its own habit.

Kind of distanceFaultyMatched
a long item in the middleto revise her notes, to finish every past paper from the last three years, and sleeping earlyto revise her notes, to finish every past paper from the last three years, and to sleep early
a clause inside an itema flat that was near the station, which had a garden, and cheapa flat that was near the station, that had a garden, and that was cheap
shared words far from the last itemThe coach wanted us to arrive early, warm up properly and that we listenThe coach wanted us to arrive early, warm up properly and listen

Notice what the fixes have in common. None of them shortens the long item. Length is not the fault; the mismatch is. A long middle item is fine as long as the item after it returns to the shape the list began with.

A useful editing move is to read the sentence with the long item cut out: 'to revise her notes ... and sleeping early.' With the middle gone, the fault is as loud as it would be in a short list. Put the middle back once the shapes match.

Picture a train. The engine sets the gauge - the width of the track - and every carriage must fit it. In a short train you can see all the wheels at once. In a long one, the last carriage is so far back that you cannot see whether it fits. So you walk along the train and check each set of wheels, one by one. A carriage built for a different gauge derails no matter how good the carriages before it were.

Long items often contain their own lists. 'We packed tents, which we borrowed from the school, sleeping bags and a stove, and we set off at dawn.' Here the outer structure is two clauses joined by 'and', and inside the first clause is a list of nouns. Checking a long sentence means checking each level separately: first the big joint, then any list inside an item. A fault can live at either level, and fixing the wrong level only moves it.

Here is where long sentences need care. Not every long sentence with 'and' is a list. 'She finished the report, and her manager, who had been waiting all week, finally smiled' joins two clauses. The first item is a clause and the second is a clause - they match, even though one is short and one is long, and even though the second has a who-clause inside it. The Match Test asks about the shape of the items at the joint, not about everything inside them. The second subtlety is the shared start. In 'to build a model, collect readings and present the results', 'to' is stated once and shared by all three. That is standard. The fault appears only when one item breaks away from the shared start - 'and presenting' - or when 'to' comes back for some items but not others. The third is the item that looks different but is not. 'The report was long, carefully researched and full of photographs' has three adjective phrases of very different lengths and builds. They all describe the report, and each works after 'The report was'. That is a match. The rule through all three: find the joint, strip each item to its shape, and judge the shape, never the length.

A student's report ends: 'In the future, the club hopes to raise more money, to recruit younger members from the primary school who have shown an interest in the garden, and that the council will give us a bigger plot.' The teacher marks it. The student protests: 'But every part of it makes sense!' The student is right - every part makes sense. The fault is not in the meaning. Two items are to-phrases after 'hopes'; the third is a that-clause. Read each one alone after the shared words and the problem appears: 'the club hopes that the council will give us' is fine, but it starts a new pattern. Surprisingly, the cleanest fix does not touch the third item's content at all. 'to raise more money, to recruit younger members ... and to win a bigger plot from the council.' Same meaning, one shape, and the sentence now ends with the weight it deserves.

This section keys only sentences where the joined items clearly share a start and one item breaks from it. It never keys a sentence wrong for being long, and it never keys an item wrong for being much longer than the others. Items of different forms that do the same job ('a doctor and proud of it') are standard and are not keyed. Stating 'to' or 'that' once for every item, or repeating it for every item, are both standard; only the half-repeat is treated as a fault. List punctuation, including the serial comma, belongs to chapter 16 and is never tested here.

  1. In every sentence longer than two lines, find the joint - and, or, but - before you check anything else.
  2. Strip each item to its first word or two and write them in a column.
  3. Read the sentence with the longest item removed; a hidden mismatch becomes loud.
  4. Fix the odd item, not the long one: length is never the fault.
  5. Check the last item most carefully, because it is furthest from the shared start.
  6. If a long item has its own list inside it, check that inner list separately.
  7. Keep the shared start stated once or repeated for all - never for some.
You can now find mismatches that distance hides. A short list shows its faults to the ear: 'swimming, cycling and to run' trips at once. A long list hides them. When the middle item runs to fifteen words, the reader - and the writer - forgets the shape the list began in, and the last item slips into a new one: 'to build a model, to collect readings for three weeks, and presenting the results.' The Match Test still works; it just has to be done on the page. Find the joint. Strip each item to its opening words. Line them up: 'to build / to collect / presenting'. The odd one shows at once. Two things are not faults. Length is not a fault: a long item is fine if it has the same shape as the others. And a shared start, stated once for every item, is standard. Fix the odd item, not the long one. That is how a long sentence keeps its grip on the reader to the last word.

Placing correlatives

A correlative pair is the Match Test with the joint split in two: the first word marks where the first item starts, the second word marks where the second item starts, and the two items must share a shape.

PlacementSentenceAfter word oneAfter word two
loose (common in speech)Priya not only plays the sitar but also the tabla.plays the sitar (verb phrase)the tabla (noun phrase)
tight (formal writing)Priya plays not only the sitar but also the tabla.the sitar (noun phrase)the tabla (noun phrase)
tight, with verbsPriya not only plays the sitar but also sings.plays the sitar (verb phrase)sings (verb phrase)

There are two ways to tighten a loose pair: slide the first word to a new place, or add words after the second so it matches what already follows the first.

Each correlative has the same rule and its own favourite slip.

PairLooseTight
either ... orYou can either pay by card or in cash.You can pay either by card or in cash.
both ... andShe both likes football and cricket.She likes both football and cricket.
neither ... norHe neither called his mother nor his father.He called neither his mother nor his father.
not only ... but alsoThe scheme not only improved attendance but also results.The scheme improved not only attendance but also results.

Notice that the fix is almost always a slide to the right: the first word moves past the verb that both items share. If the items are really two different actions, the first word stays where it is and the second item gets its own verb: 'She not only wrote the song but also sang it.'

Some sentences need a bigger move. 'Either Arjun is tired or bored' puts a whole clause after 'either' and an adjective after 'or'. Sliding gives 'Arjun is either tired or bored' - two adjectives, both describing Arjun after 'is'. The test is always the same: read what follows each word, and see whether the two could swap places.

Picture a see-saw in a playground. The first correlative word is where one child sits; the second is where the other sits. If one child sits right at the end and the other halfway along, the see-saw tips - it still works, children play on it all the time, but it is not level. Sliding the first word along is moving that child to the matching seat, so the board balances.

'Whether ... or' works the same way and is common in essays: 'The question is whether the dam will help farmers or harm them' pairs two verb phrases after the shared subject. Sometimes the second item drops words it shares with the first - 'whether the dam will help or harm farmers' - and that is still tight, because 'help' and 'harm' are both verbs sharing 'farmers'. Shared words can sit at the start, the end, or both, as long as what remains after each correlative matches.

Here is where placement needs care. First, tight placement is a written convention, not a law of English. Usage guides that recommend it also describe loose placement as common in speech and informal writing, and it almost never causes misreading. That is why this section keys the tight version only where the text is formal - a report, an application, an essay - and never marks casual speech wrong. Second, sometimes moving the first word changes the meaning. 'He did not only the washing but also the ironing' is tight but clumsy, because 'did not' side by side reads at first as a negative. The better formal fix is often to give the second item its verb: 'He not only did the washing but also did the ironing', or simply 'He did both the washing and the ironing.' Tightness that sounds awkward is not the goal; matching shapes are. Third, both words must start a real item. 'Both Ravi and' needs something after 'and' that matches 'Ravi' - a name, a person, a noun phrase. A pair that ends after the first item - 'We invited both Ravi' - is simply unfinished. The rule through all three: in formal writing, what follows the first word and what follows the second word should be able to swap places.

Two students write the same fact in a science report. Student one: 'The experiment not only failed once but also twice.' Student two: 'The experiment failed not only once but also twice.' The first student's teacher circles 'not only' and writes 'move'. The student is puzzled: the sentence is clear. It is. But look at the swap test. In the tight version, 'once' and 'twice' are both adverbs, and they could change places: 'failed not only twice but also once' is odd in meaning but perfectly shaped. In the loose version, 'failed once' and 'twice' cannot swap - 'not only twice but also failed once' makes no sense. Surprisingly, a two-word slide is the whole difference between a sentence that is merely clear and one that is balanced.

This section keys tight placement only when the stem says the text is formal or written - a report, an application, minutes, an essay. Loose placement is described as common and acceptable in speech and is never keyed as an error there. Inverted 'Not only did she ...' openings are standard and belong to Master S33, where the major usage guides' different positions are compared. Choices never differ only in punctuation. No claim is made about how often examiners test this.

  1. When you write either, both, neither or not only, ask what item it belongs to.
  2. Put the first word straight before that item, not before a verb both items share.
  3. Underline what follows each word and check that the two could swap places.
  4. If sliding the first word sounds clumsy, give the second item its own verb instead.
  5. Use tight placement in reports, essays, applications and formal letters.
  6. Leave loose placement alone in dialogue, speeches written to sound spoken, and casual writing.
  7. Keep 'but also' together in formal writing, unless you choose the plainer 'and'.
You can now place correlatives. A correlative pair splits the joint in two: either...or, both...and, neither...nor, not only...but also. The first word marks where the first item starts, and the second word marks where the second item starts. For the pair to balance, the two items must share a shape. The common slip is putting the first word too early, before a verb both items share. 'She both likes football and cricket' pairs a verb phrase with a noun. Slide 'both' past the verb - 'She likes both football and cricket' - and two nouns line up. That slip is normal in speech and almost never misread. In formal writing, careful writers expect the tight version, and so do most examiners. The swap test settles it: what follows each word should be able to change places. That is the Match Test, applied to a pair.

The rhythm of three

A rhythm of three is the Match Test used for effect: find the joint, give all three items one shape, and the matching itself becomes something the listener can hear.

LineThe three itemsShapeWhat it does
government of the people, by the people, for the people (Lincoln)of / by / for the peopleprepositional phraseonly one word changes, so the change is what we notice
Friends, Romans, countrymen (Shakespeare)friends / Romans / countrymennounthree ways of addressing one crowd, widening each time
The monsoon filled the wells, flooded the roads and washed the dust from every roof.filled / flooded / washedverb phraseeach item longer than the last - the line builds

Two items feel like a pair or a contrast. Four or more feel like a list. Three is the smallest number that sets up a pattern and then completes it.

Three is not magic on its own. The effect comes from the shape holding, and it can be tuned.

MoveExampleEffect
equal itemsWe will learn together, work together and win together.a steady, chant-like beat
rising itemsThe storm broke branches, flattened fences and tore the roof off the school hall.a build to the biggest item
repeated little wordfor honesty, for courage and for kindnesseach item given its own weight
broken itemWe will learn together, work together and we might win.the beat collapses - unless the writer means it to

Rising items - short, longer, longest - are sometimes called the rule of increasing members. It is a tendency speakers use, not a law; a three of equal items is just as valid, and suits a chant or a slogan.

The oldest famous three may be the Latin 'veni, vidi, vici', attributed to Julius Caesar and usually translated 'I came, I saw, I conquered'. Three clauses, each a subject and one verb, each shorter to say than to do. Its power is the shape: identical frames make the difference between the verbs - came, saw, conquered - the only thing left to hear.

Picture a drummer counting a band in: one, two, three - and on the fourth beat, the music starts. The first two beats set the tempo; the third confirms it; the listener's body is ready. A tricolon works the same way. The first item sets a shape, the second confirms it, and the third lands on the beat the listener already expects. If the drummer fumbles the third beat, nobody knows when to start.

A tricolon can be made of single words, phrases or whole clauses, and the longer the items, the more the shape has to be heard rather than seen. 'We will not tire, we will not falter and we will not fail' repeats a frame across three clauses - which is also a repeated opening, the subject of the next section. Three items that start the same way combine two effects at once: the beat of three and the insistence of repetition.

Here is where the rhythm of three needs care. First, the shape has to hold, but the items do not have to be the same length. Lincoln's three are almost identical. 'The monsoon filled the wells, flooded the roads and washed the dust from every roof in the village' has three verb phrases of growing length. Both are tricolons. What they share is the shape, not the size. Second, the effect is described, not measured. Writers and teachers of rhetoric have long noted that three items feel complete and are easy to remember. That is a widely shared observation about how listeners respond, not a law with numbers behind it. This section names the effects and never claims a three is always stronger than a two. Third, not every list of three is a tricolon for effect. 'Bring a pen, a ruler and a calculator' has three matching items because the exam needs three things. A tricolon is three items used for their rhythm. The grammar is the same; the purpose is different. The skill through all three: choose three when you want completeness, and make all three items share a shape so the listener can hear it.

Two versions of a class captain's closing line. 'We worked hard, we helped each other and we won.' 'We worked hard, we helped each other, we won.' Both are three matching clauses. The only difference is the 'and' before the last one. Surprisingly, dropping the 'and' can change the feel. With 'and', the list sounds finished and settled. Without it, each clause stands alone, and the line sounds faster and more emphatic, as if the speaker is counting the achievements off on her fingers. Neither is wrong. They are two versions of the same three, tuned differently. (Punctuating lists belongs to chapter 16; here the point is the rhythm the joining word creates.)

This section describes the effects of a tricolon - rhythm, completeness, memorability, a build - as observations that writers and teachers of rhetoric widely share, not as measured facts. It never keys a sentence wrong for having two items or four, and never claims three is always best. Quotations are limited to public-domain texts: Lincoln's Gettysburg Address and Shakespeare's Julius Caesar; 'veni, vidi, vici' is given as traditionally attributed. A deliberately broken third item is a separate technique, treated in S28.

  1. Use a rhythm of three at the moments you want remembered: an opening, a conclusion, a slogan.
  2. Give all three items one shape - three adjectives, three verb phrases, three clauses.
  3. For a build, put the longest or strongest item last.
  4. For a steady chant, keep the three items close in length.
  5. Make every item earn its place; cut a third item that only pads.
  6. Repeat a small word - 'for', 'we will' - when you want each item to carry its own weight.
  7. Read the line aloud; if the third beat stumbles, check its shape first.
You can now use the rhythm of three. A tricolon is three items of one shape, used for effect. Lincoln's 'of the people, by the people, for the people' changes one word and keeps the frame. Shakespeare's 'Friends, Romans, countrymen' widens its address with three nouns. 'The monsoon filled the wells, flooded the roads and washed the dust from every roof' builds from short to long. The effects are well known: a beat the listener can hear, a feeling of completeness, a line that is easy to remember, and - with the longest item last - a build to a climax. The effect depends on the shape. 'Our team was fast, fearless and we never gave up' sets up a beat and then drops it. Match the third item - 'fast, fearless and tireless' - and the line lands. Three is a tool, not a rule. Use it when you want the reader to feel something complete.

Repetition for effect

Anaphora and epistrophe sit on top of the Match Test: the items already share a shape, and the writer chooses to repeat the same words at the start or the end of every one.

FigureWhere the repeat sitsExampleOften used for
anaphorathe start of each itemI will listen to you. I will speak for you. I will work for you.insistence, a building pulse
epistrophethe end of each itemI spake as a child, I understood as a child, I thought as a child (1 Corinthians 13, King James Bible)returning every line to one idea
epistrophe in a threethe end of each item, with only the first word changingof the people, by the people, for the people (Lincoln)a frame in which only one word moves

In every row, the repeated words stay still so that something else can move. The listener's attention goes to the part that changes.

Repetition only works when the items underneath it are parallel. If one item changes shape, the repeat either breaks or has to be dropped.

VersionSentenceWhat happens
anaphora heldWe will clean the river, we will plant the trees and we will guard the bank.three clauses, one opening - a steady pulse
shape brokenWe will clean the river, we will plant the trees and guarding the bank.the third item cannot take 'we will', so the pulse stops
stated onceWe will clean the river, plant the trees and guard the bank.parallel and standard - quieter, quicker
epistrophe heldShe worked for them, she cooked for them and she cared for them.every clause returns to 'them'

'Stated once' is not a mistake. It is the plainer choice. Anaphora is the louder one, and a writer chooses between them for the effect they want.

The Sermon on the Mount in the King James Bible opens with a run of anaphora: 'Blessed are the poor in spirit: for theirs is the kingdom of heaven. Blessed are they that mourn: for they shall be comforted.' Each verse repeats 'Blessed are', names a different group, and gives a reason. The repeated opening turns a list of groups into a rhythm, and the variation - the poor, the mourners, the meek - is what the listener remembers.

Picture a lighthouse. Its beam sweeps round and returns to the same point on the sea, again and again. Anaphora is the beam starting from the same place each time; epistrophe is the beam always coming back to rest on the same rock. What you see in between - a different ship, a different wave on every sweep - stands out precisely because the light keeps returning.

Repetition can happen at more than one level. Lincoln's 'of the people, by the people, for the people' repeats 'the people' at the end (epistrophe) inside a rhythm of three. Shylock's lines in The Merchant of Venice - 'If you prick us, do we not bleed? If you tickle us, do we not laugh?' - repeat both an opening ('If you') and a middle frame ('do we not'). The more of the frame that repeats, the smaller and louder the part that changes.

Here is where repetition needs care. First, anaphora and the half-repeat look alike but are opposites. Anaphora repeats the opening for every item: 'I will listen, I will speak, I will work.' The half-repeat does it for some: 'I will listen, I will speak and work.' The first is a choice with an effect; the second is a slip careful writers avoid. Count the repeats against the items. Second, repetition is described in terms of effect, and effects depend on context. The same anaphora that stirs a crowd at a rally can sound heavy in a short email. A writer judges the setting. This section names the effects that repetition is commonly used for - insistence, emphasis, a pulse, memorability - and never claims it always produces them. Third, epistrophe is quieter than anaphora and easier to miss. The listener only hears it at the end of each item, after the new material. That is why it suits lines that keep returning to one idea - 'as a child', 'for them', 'the people'. The skill through all three: repeat for every item, keep the shape underneath matched, and make sure something moves between the repeats.

A student is told to cut repetition from her speech. She deletes every 'we will' after the first one: Before: 'We will fix the fans. We will open the library at lunch. We will listen to every class.' After: 'We will fix the fans, open the library at lunch and listen to every class.' Both versions are parallel. Both are correct. But the student notices that the audience at her practice run cheered at the end of the version with three 'we will's, and sat quietly after the shorter one. Surprisingly, the teacher's advice and her audience were both right. Repetition in an essay often wastes words. Repetition in a speech, spoken aloud to a room, gives the listener a beat to hold on to. The same grammar; two different jobs.

This section describes common effects of anaphora and epistrophe - insistence, a pulse, emphasis, memorability - as observations about how they are used, not as measured facts, and never keys repetition as bad style. Stating a shared opening once is also standard and is never keyed wrong. Quotations are from public-domain texts: the King James Bible (1 Corinthians 13, Matthew 5), Shakespeare's The Merchant of Venice and Lincoln's Gettysburg Address. Twentieth-century speeches that use anaphora are described, not quoted.

  1. Choose anaphora when you want insistence - promises, appeals, calls to action.
  2. Choose epistrophe when you want every item to return to one idea.
  3. Repeat the words for every item; never stop part-way.
  4. Keep the shape under the repeat matched, or the repeat will not fit.
  5. Make sure something changes between repeats - that is what the listener remembers.
  6. In essays and emails, prefer stating the shared words once unless you want a strong effect.
  7. Read the passage aloud; repetition is written for the ear.
You can now use repetition for effect. Anaphora repeats the same words at the start of each parallel item: 'I will listen to you. I will speak for you. I will work for you.' Epistrophe repeats them at the end: 'I spake as a child, I understood as a child, I thought as a child.' Lincoln's 'of the people, by the people, for the people' repeats 'the people' at the end of every item, so only one word moves. Both rest on parallel structure. The repeat fits only because every item has the same shape. When one item breaks - 'and guarding the bank' - the repeat breaks with it. Both are choices. Stating the shared words once is plainer and just as standard. Repeating them is louder, and suits speeches, appeals and prayers. Repeat for every item, keep the shape matched, and let one part move each time.

Balance and contrast

Antithesis is the Match Test applied to a contrast: two opposite ideas, each given the same shape, so the frame stays still and only the opposites move.

PatternExampleMatching halves
X ..., Y ...It was the best of times, it was the worst of times. (Dickens)two clauses: it was the ___ of times
not ... but ...Not that I loved Caesar less, but that I loved Rome more. (Shakespeare)two that-clauses
less ..., more ...Talk less, listen more.two verb phrases
X, not YMeena came to the city for an education, not for money.two phrases starting with 'for'

The more of the frame that repeats, the louder the opposites. In 'it was the best of times / it was the worst of times', five words out of six are shared.

A contrast breaks when its second half changes shape, and the fix is always the same: rebuild the second half on the first half's frame.

UnbalancedBalancedWhat changed
Neha wanted a job that paid well rather than being famous.Neha wanted a job that paid well rather than one that made her famous.-ing phrase to noun phrase with a that-clause
Win with grace, and losing should be dignified.Win with grace, and lose with dignity.clause to verb phrase
Ravi was quick to anger but forgiving was slow.Ravi was quick to anger but slow to forgive.clause to adjective phrase

Notice that 'Ravi was quick to anger but slow to forgive' is a double antithesis: quick against slow, and anger against forgive. Matching shapes let a single sentence carry two contrasts at once.

The King James Bible is full of antithesis. Ecclesiastes 3 pairs opposites in one frame: 'a time to weep, and a time to laugh; a time to mourn, and a time to dance'. Proverbs 15 opens: 'A soft answer turneth away wrath: but grievous words stir up anger.' Soft against grievous, turning away against stirring up - two clauses built to the same plan, pointing in opposite directions.

Picture an old pan balance in a spice shop. Two pans, one beam, and the shopkeeper watching the pointer. If the pans are the same size and shape, you can see at once which side is heavier. If one pan is a bowl and the other a flat plate, the comparison is muddled before you start. Antithesis gives both ideas the same pan, so the reader can see the difference in weight.

'The more ..., the more ...' is a special antithesis frame that English grammar builds in: 'The more you practise, the less you fear.' Both halves must start with 'the' and a comparative, and each needs its own clause. 'The more you practise, and you will fear less' breaks the frame. When the frame holds, the two halves move together like two ends of a see-saw - one rises, the other falls.

Here is where antithesis needs care. First, the halves must match in shape, but they do not have to match in grammar word for word. 'Not that I loved Caesar less, but that I loved Rome more' repeats 'that I loved' exactly. 'Meena came for an education, not for money' drops the verb in the second half. Both are balanced: the second half has the same shape as the part of the first half it is contrasted with. Second, some contrasts are balanced with different forms that do the same job. 'She was a doctor, not proud of it' sets a noun phrase against an adjective phrase, and both describe her - the kind of pairing grammarians accept. But in an antithesis, a writer usually wants the strongest balance, so the matched version ('a doctor, not a boaster') tends to land harder. That is a judgement about effect, not a rule about correctness. Third, antithesis and the correlative 'not only ... but also' are different. 'Not only ... but also' adds; 'not ... but' opposes. 'Not for money but for education' rejects money. 'Not only for money but also for education' keeps it. The rule through all three: build the second half on the first half's frame, and let only the opposites change.

Two versions of a line for a school's anti-bullying poster. 'Be kind to others, because being cruel hurts people.' 'Kindness costs nothing; cruelty costs everything.' The first is a reasonable sentence. It gives an instruction and a reason. The second is shorter, and it is the one students remember at the end of the week. Surprisingly, the second says less. It does not explain why cruelty costs everything. What it does is set two opposites - kindness and cruelty, nothing and everything - in one frame: '___ costs ___'. The frame does the explaining. Once the reader has seen the balance, the conclusion is theirs to draw.

This section keys a contrast as unbalanced only when its second half changes shape against the first. It never keys a same-job pairing like 'a doctor and proud of it' as wrong, and it describes the effect of antithesis - sharpness, memorability - as a common observation, not a measured fact. Quotations are from public-domain texts: Dickens's A Tale of Two Cities, Shakespeare's Julius Caesar, and the King James Bible (Ecclesiastes 3, Proverbs 15). Twentieth-century antitheses in speeches are left to Master, where they are described rather than quoted.

  1. When your writing sets two ideas against each other, try putting them in one frame.
  2. Choose true opposites for the words that change - best/worst, less/more, soft/grievous.
  3. Keep everything else in the two halves as similar as you can.
  4. Check the second half by reading it straight after the shared words.
  5. Use 'not ... but' to reject one idea, 'less ... more' to shift weight, 'X, not Y' to correct.
  6. Save antithesis for moments that need a sharp contrast: openings, turning points, conclusions.
  7. Read the line aloud; a balanced antithesis sounds like two halves of one breath.
You can now build balance and contrast. Antithesis sets two opposite ideas side by side in matching shapes. Dickens's 'It was the best of times, it was the worst of times' keeps one frame and changes one word. Brutus's 'Not that I loved Caesar less, but that I loved Rome more' balances two that-clauses and two pairs of opposites. 'Talk less, listen more' does it in four words. The matched shape is what makes the contrast visible. With everything else the same, the reader's attention goes straight to the opposites. When the second half changes shape - 'a job that paid well rather than being famous' - the balance tips. Rebuild it on the first half's frame - 'rather than one that made her famous' - and the contrast lands. Keep the frame, change only the opposites.

Parallelism in speeches

A speech runs the Match Test for the audience: the speaker finds the joint and matches the items, so that the listener, who cannot look back, can still hear where each item starts and ends.

ToolWhat the listener hearsExample
rhythm of threea pattern set up and completedWe few, we happy few, we band of brothers (Shakespeare, Henry V)
repeated openinga signal that a new item has begunWith malice toward none, with charity for all (Lincoln, 1865)
antithesistwo opposites that sharpen each otherI come to bury Caesar, not to praise him (Shakespeare, Julius Caesar)

A reader sees commas, bullet points and paragraphs. A listener has only sound. Repeated words and matching shapes do the job punctuation does on the page.

The famous speeches of history tend to stack the tools, often in the same passage.

SpeechWhat it does
Lincoln, Gettysburg, 1863ends on a three with epistrophe: 'government of the people, by the people, for the people'
Lincoln, second inauguration, 1865a repeated 'with' across three items; the first two are opposites
Churchill to the House of Commons, 1940a long passage built on one repeated promise, naming place after place where the fight would go on (described, not quoted - the speech is still under copyright)
Martin Luther King Jr., Washington, 1963a closing section in which one short phrase opens line after line, each line naming a different hope (described, not quoted)

What they share is not a style but a structure. Every item in each pattern has the same shape, so the audience can feel the pattern and anticipate the next item before it arrives.

Shakespeare wrote speeches for the stage that use the same tools. Henry V, before the battle of Agincourt: 'We few, we happy few, we band of brothers.' Three noun phrases, each opening with 'we', each longer and warmer than the last. The soldiers - and the audience - are named three times, and by the third they are brothers.

Picture the audience walking through a dark hall, holding a rope that you, the speaker, have laid out for them. As long as the rope runs in a straight line, they follow without thinking. Parallel structure is that rope. Every matching item is another length of rope in the same direction. A broken item is a knot or a gap - the audience stops, feels around, and in that moment they stop listening to what you are saying.

Speeches often combine a pattern across sentences, not just inside one. A speaker might open three paragraphs with 'Imagine a school where ...', each describing a different improvement. The listener hears the repeated opening as a signpost: a new point is starting, and it belongs with the last one. Written essays do the same thing more quietly with matching topic sentences - which is where the next section begins.

Here is where speech patterns need care. First, the effects are real but not guaranteed. People who study rhetoric have long observed that listeners follow, remember and respond to parallel patterns. That is a widely shared observation, not a law: a speech can be built on patterns and still fall flat, and a plain speech can move people. This section never claims a pattern always works. Second, the patterns must be heard, not just seen. A written list with bullet points can hold items of different lengths and styles; the reader sees where each begins. A spoken list needs something audible - a repeated word, a matching shape - to mark the boundaries. That is why speakers repeat little words ('with ... with ... with') that a writer might state once. Third, a speaker can break a pattern on purpose. After three matching items, a short, different line can land like a full stop: that is the subject of S28. The break works only because the pattern was clear first, and because the speaker chose the moment. The rule through all three: build the moments that matter on patterns the ear can hear, and keep every item in the pattern to one shape.

Two students give the same speech in a school debate: 'This house would ban homework.' The first ends: 'Homework takes time from sleep, it takes time from family, and there is not enough time for sport either.' The second ends: 'Homework takes time from sleep. It takes time from family. It takes time from sport.' The judges score the arguments equal. But the audience vote goes to the second student by a wide margin. Surprisingly, the second ending makes the same three points in fewer words. What changed is the frame: 'takes time from' three times, with only the last word moving. The audience heard a pattern, anticipated the third item, and was waiting for it when it came. The first student's third point was just as good - it simply arrived in a different shape, and the room did not hear it as the end.

This section describes why speakers use parallel patterns and what listeners commonly report, not measured effects. Quotations are limited to public-domain texts: Lincoln's Gettysburg Address and second inaugural address, and Shakespeare's Henry V and Julius Caesar. Speeches by Churchill (1940), King (1963) and other twentieth-century speakers are described without quotation because they remain under copyright. No item keys repetition as bad style, and deliberate pattern breaks are left to S28.

  1. Build the opening, the turning point and the close of a speech on a parallel pattern.
  2. Repeat a small word - 'with', 'we', 'for' - so the listener hears each item start.
  3. Use a rhythm of three for the moment that must feel complete.
  4. Use a balanced contrast for the moment you change direction.
  5. Keep every item in a pattern to one shape, especially the last.
  6. Use patterns at key moments, not in every sentence.
  7. Describe and credit famous modern speeches; do not borrow their words.
  8. Practise the patterned lines aloud until the last item lands on the beat.
You can now read and build parallelism in speeches. A listener cannot re-read. Speakers make up for that with patterns the ear can hear, and nearly all of them are parallel: the rhythm of three ('We few, we happy few, we band of brothers'), repetition ('With malice toward none, with charity for all') and antithesis ('I come to bury Caesar, not to praise him'). Famous speeches stack these tools. Lincoln ends Gettysburg on a three with a repeated ending. Twentieth-century speakers built whole passages on a repeated opening - and because their words are still under copyright, we describe those passages rather than quote them. The patterns only work if every item holds the shape. A broken item at the climax - 'in the heat, in the rain and when it was dark' - is where the audience loses the thread. Build key moments on audible patterns, and keep every item to one shape.

Parallelism in essays

An essay's skeleton is the Match Test at the scale of a whole text: the thesis is the joint, each point is an item, and every later part of the essay must pick up those items in the same shape and order.

PartMatchedWhat the reader gets
thesisUniforms save families money, reduce the pressure to follow fashion and build a sense of belonging.a plan: three points, one shape
topic sentencesUniforms save families money. / Uniforms reduce the pressure to follow fashion. / Uniforms build a sense of belonging.signposts that match the plan
headings (reports)Saving money / Reducing pressure / Building belonginga contents list in one shape
conclusionBy saving money, reducing pressure and building belonging, uniforms serve every student.the plan, completed

The shape can change between parts - verb phrases in the thesis, -ing headings in a report - but within each part, every item shares one shape.

The faults in an essay's skeleton are the same faults you have met in sentences, only spread across a page.

FaultExampleFix
mixed thesisPhones help students research, record notes and they distract others.... research, record notes and distract others.
mixed headingsWhy the park matters / Threats to the park / Saving itWhy the park matters / What threatens it / How to save it
order brokenThesis: cost, safety, comfort. Paragraphs: safety, cost, comfort.Reorder the paragraphs, or the thesis, so they agree.
conclusion driftsThesis: cool streets, clean air, calm minds. Conclusion: shade, and the air is cleaner, and people feel better.Trees cool our streets, clean our air and calm our minds.

The order matters as much as the shape. A thesis that lists three points is a promise, and paragraphs that arrive in a different order break it, even if every sentence is parallel.

Matching is not the same as repeating. Topic sentences can echo the thesis in the same shape without copying it word for word: 'Uniforms save money' can become 'The first benefit is financial' - as long as all three topic sentences use that same new frame ('The second benefit is social ...'). A new frame is fine; a different frame for each paragraph is what loses the reader.

Picture the plan of a house on an architect's table. The thesis is the plan: three rooms, drawn to one scale, labelled in one style. The topic sentences are the doors into each room, and the headings are the room names on the doors. If one room is drawn to a different scale, or one door is labelled in another language, visitors get lost. The conclusion is the view back from the garden - the same three rooms, seen together.

Parallel structure also works inside a single body paragraph. A paragraph that gives two examples can give them in matching shapes - 'In Delhi, the scheme cut costs by half; in Pune, it doubled the number of users' - so the reader can compare them at a glance. The essay's skeleton, the paragraph's structure and the sentence's list are three levels of the same move: find the joint, match the items.

Here is where essay structure needs care. First, the thesis items can be matched in more than one way, and all are standard. 'Uniforms save money, reduce pressure and build belonging' (verb phrases) and 'Uniforms bring savings, less pressure and belonging' (noun phrases) both work. What matters is choosing one shape for all the points. Second, some thesis lists mix forms that do the same job, and grammarians accept them. 'This essay discusses the causes of the flood, its effects and how the town should prepare' puts a how-clause beside two noun phrases, all as things discussed. That is standard English. Many editors would still match them - 'the causes, the effects and the preparations' - because a matched preview is easier to scan. This section treats that as a style improvement, not an error. Third, stating a little word once or for every item is both standard: 'the causes, effects and cures' and 'the causes, the effects and the cures'. The half-repeat - 'the causes, the effects and cures' - is the one careful writers avoid. The rule through all three: give the thesis one shape, follow it in the same order, and keep matching within each part of the essay.

Two students write essays on the same question and make the same three points, in the same order, with the same evidence. Student one's thesis: 'Libraries matter because of free books, people use them to study, and they are safe.' Student two's thesis: 'Libraries matter because they lend books freely, give students space to study and offer everyone a safe place to be.' The marks come back. Student two scores higher for 'organisation', though the paragraphs are almost identical. Surprisingly, the difference is one sentence. Student two's reader knew from the introduction exactly what was coming, in what order, and in what form. Every body paragraph then confirmed a promise instead of making a new one. The organisation mark was earned in the thesis.

This section keys a thesis, heading set or conclusion as unmatched only when its items clearly change shape in a way careful writers reject. It never keys a same-job pairing (a noun phrase beside a how-clause as objects of 'discuss') as an error; matching it is described as a style improvement. Stating 'the' or 'to' once for all items and repeating it for all are both standard. No claim is made about how any particular exam board awards organisation marks; the surprise example is illustrative.

  1. Write your thesis points in one shape - all verb phrases, all noun phrases or all clauses.
  2. Number them in your plan and keep that order through the essay.
  3. Open each body paragraph with a topic sentence that picks up its point in a matching frame.
  4. Give report headings one shape - all -ing phrases, all questions or all noun phrases.
  5. Echo the three points in the conclusion in matching form, without copying word for word.
  6. Inside paragraphs, give matching examples matching shapes, so they can be compared.
  7. Check the skeleton by copying out the thesis, topic sentences and conclusion on one page.
You can now use parallel structure to build an essay's skeleton. The thesis is the joint. Its points are the items, and they should share one shape: 'Uniforms save families money, reduce the pressure to follow fashion and build a sense of belonging.' A mixed thesis - a verb phrase, a clause and a noun phrase - makes the reader rebuild the plan. The topic sentences pick up the points in the same order and in a matching frame. Headings in a report share one shape. The conclusion echoes the three, in matching form, without copying. Order is part of the promise. A thesis that lists cost, safety and comfort must be followed by paragraphs on cost, safety and comfort, in that order. Within each part, one shape. Across the essay, one order. That is the skeleton a reader can see.

Breaking the pattern

The Match Test tells you where a pattern breaks. Breaking the pattern adds one question before the verdict: what is the writer trying to do?

BreakExamplePurposeVerdict
the surprising last itempolite, charming and a thiefa comic or sinister twisttechnique
the short line after a threeWe fixed the roof, we painted the walls, we planted the garden. Then the rain came.a sudden turntechnique
variety after monotonyfour sentences all starting 'Sophie ...'a lively morningvary the frame
the unplanned changeThe committee will review the budget, check the accounts and a new treasurer.a plain, formal listslip - match it

A pattern can also break in meaning while the grammar holds: 'a tent, a torch and her grandmother's parrot' keeps three noun phrases and still surprises.

Deliberate breaks come in a few recognisable kinds, and each depends on a clear pattern first.

KindHow it worksExample
the twistthe last item changes shape or kindRohan studied all night, slept for an hour, walked into the exam hall - and forgot his pen.
the short stopa long pattern, then a very short sentenceWe had trained for months. We had planned every detail. We lost.
the interruptiona phrase breaks into the last itemMeera wanted to travel, to write and, more than anything, to sleep.
the releaseafter many matched sentences, a different frame gives the reader airSophie woke. Sophie dressed. Sophie ate. Then the phone rang, and the whole day changed.

In every kind, the break works because the pattern came first and was clear. A break in a passage with no pattern is not a technique - there is nothing to break.

A useful test for your own writing: if you had to explain the break to a reader, could you say what it does in one sentence? 'The third item is a noun so it lands as a surprise' is an explanation. 'I didn't notice' is not. The first is a break to keep. The second is a list to match.

Picture a row of streetlights along a road at night, evenly spaced. A driver relaxes into the rhythm. If one light is missing because a bulb has blown, the dark gap is a hazard - nobody meant it. If the road ends at a lit-up sign that says STOP, the break in the pattern is the whole point, and the driver notices it because of the lights that came before. Same break in rhythm; one is a fault, the other is a message.

A pattern can break in form or in meaning, and the two are different tools. 'Polite, charming and a thief' breaks the form - two adjectives, then a noun phrase. 'A tent, a torch and her grandmother's parrot' holds the form - three noun phrases - and breaks the meaning: the third is not camping gear. Holding the form while breaking the meaning is often the safer twist, because it keeps the rhythm and still surprises.

Here is where breaking the pattern needs care. First, the verdict depends on information outside the sentence. 'The trip was educational, well organised and we all got sunburnt' is a punchline in a comic magazine piece and a slip in a formal report. The grammar is identical. That is why this section never judges a break without a stated purpose, and why your own editing should start by writing the purpose down. Second, some breaks are standard English whatever the purpose. 'Polite, charming and a thief' pairs adjectives with a noun phrase, all describing one person - a same-job pairing grammarians accept. Other breaks are faults careful writers reject in any register: 'The committee will review the budget, check the accounts and a new treasurer' leaves 'a new treasurer' with no verb to attach to. A deliberate twist is much more convincing when the broken item is still grammatical. Third, variety is not the same as randomness. Curing monotony means choosing a new frame on purpose - often at a turning point in the passage - not scattering shapes at random. The rule through all three: find the pattern, find the break, name the purpose, then decide.

A student writes a story about a school sports day. The last paragraph reads: 'Arjun had trained every morning. He had eaten well. He had slept early. He came fourth.' Her teacher writes 'good' in the margin. A classmate, checking it for parallel structure, points out that the last sentence breaks the pattern: three sentences with 'had', and then one without. Surprisingly, the classmate has found exactly the right thing and drawn the wrong conclusion. The break is the whole point. Three matched sentences of effort set up an expectation of victory, and the short, differently shaped last sentence knocks it over. The pattern exists so that the break can hurt. Change 'He came fourth' to 'He had come fourth' to match, and the ending loses its punch.

This section never keys a pattern break as a fault without first stating the writer's purpose - a formal report, minutes, a job advertisement, a plain list. Deliberate breaks for surprise, emphasis or variety are described as techniques. Same-job pairings ('polite, charming and a thief') are standard English and are never keyed wrong. The effects of breaks are described as what writers use them for, not as guaranteed results. Punctuation that sets off a break (a dash, a full stop) belongs to chapter 16 and is not tested here.

  1. Before you judge a break - yours or someone else's - write down the writer's purpose.
  2. Keep a break that serves the purpose: a twist, a short stop, a release after monotony.
  3. Match a break that works against the purpose, especially in formal writing.
  4. Set up a clear pattern before you break it; a twist needs something to twist.
  5. Prefer twists that keep the grammar sound - a surprising noun in a list of nouns.
  6. If matched sentences start to sound mechanical, change the frame at a turning point.
  7. Test every break by explaining it in one sentence; if you cannot, match the items.
You can now break a pattern on purpose - and tell when a break is a slip. A deliberate break needs a pattern first. 'Polite, charming and a thief' sets up two adjectives and lands a noun phrase. 'We had trained for months. We had planned every detail. We lost.' follows a long pattern with a short stop. A surprise can also come in meaning while the form holds: 'a tent, a torch and her grandmother's parrot'. Too much matching can cause its own problem. Four sentences in one frame can sound mechanical, unless dullness is what the writer wants. The verdict depends on purpose. 'The trip was educational, well organised and we all got sunburnt' can be a punchline or a slip; only the writer's purpose decides. In formal minutes or reports, where nothing is meant to surprise, an unplanned break is a slip to match. Find the pattern, find the break, name the purpose, then decide.

Parallelism in CVs and forms

Practical writing runs the Match Test on every list: the bullet points or the list items are joined, so each must start in the same shape - most often an action verb.

DocumentMatchedShape
CV achievementsLed the eco-club / Managed the garden / Raised money for toolspast action verb
skillscoding / public speaking / video editing-ing phrase or noun
job dutiesanswering the phone / greeting visitors / keeping the diary-ing phrase
form instructionsComplete every section. Sign at the bottom. Attach a photograph.command

A reader scanning a list reads the first word of each line. When those first words share a shape, the scan is quick and nothing is missed.

Each kind of practical list has its own usual shape, and its own favourite slip.

ListSlipMatched

'Responsible for' is a very common CV slip. It describes a duty rather than an action, and it breaks a column of verbs. Replacing it with a verb - managed, ran, looked after - usually makes the bullet stronger as well as parallel.

Not every mix is a fault. 'I am a trained lifeguard and confident in deep water' pairs a noun phrase with an adjective phrase, and both describe you. That is standard English - the same-job pairing you met at the start of the chapter. In a bullet list, though, readers expect one shape, so it is usually worth matching the bullets even where a sentence could mix.

Picture a shelf of files in an office, each with a label on its spine. If every label starts with a date, the clerk can run a finger along the shelf and find the one she needs in seconds. If some labels start with a date, some with a name and some with a colour, she has to stop and read each one. Bullet points are labels on a shelf. The first word is what the reader's finger runs along.

A CV often has two lists that use different verb forms, and that is not a fault. The 'Current role' section may use present verbs ('Manage a team of four'), and 'Previous roles' past verbs ('Managed a team of four'). Parallel structure asks for one shape within each list, not the same shape across the whole document. Each list matches itself; the time is a separate question, the one chapter 13 is about.

Here is where practical lists need care. First, the shape to match is set by the first item and by the heading. Under 'Achievements', readers expect actions, so past verbs work best. Under 'Skills', readers expect things you can do, so nouns or -ing phrases work best: 'coding, public speaking, video editing'. Under 'Duties' in a job advertisement, -ing phrases are common: 'answering the phone, greeting visitors'. Match the heading's promise. Second, same-job pairings that are standard in sentences are still standard: 'reliable, punctual and a quick learner' describes you in three ways. But bullet points are read as a column, and a column in one shape is easier to scan. So a careful writer will often match even where the grammar allows a mix - a choice for the reader's speed, not a correction. Third, repeated little words work the same way here as anywhere: 'to study medicine, to work in rural clinics and to train nurses' and 'to study medicine, work in rural clinics and train nurses' are both standard. The half-repeat - 'to study medicine, work in rural clinics and to train nurses' - is the one to avoid. The rule through all three: set the shape with the heading and the first item, and hold it down the column.

Two students apply for the same summer volunteering post. Both have done almost exactly the same things. The first lists: 'Class monitor. Helped with the book sale. I also ran the quiz club. Tutoring juniors in maths.' The second lists: 'Monitored Class 9B. Ran the school book sale. Founded the quiz club. Tutored juniors in maths.' The second student gets the interview. Surprisingly, the second list is not longer, more detailed or more impressive in content. What changed is that every line starts with a past action verb - monitored, ran, founded, tutored - so the reader sees four things done, one after another. The first list says the same things in four different shapes, and a quick reader sees a jumble. (This is an illustrative case, not a report of how any organisation actually chooses.)

This section keys a practical list as unmatched only when one item clearly changes shape against the heading and the other items. Same-job pairings ('a trained lifeguard and confident in deep water', 'reliable, punctual and a quick learner') are standard and are never keyed wrong; matching them is described as a choice for scanning. Present and past verbs in different sections of a CV are not a parallel fault. The surprise example is illustrative; no claim is made about how employers or admissions teams actually decide. Bullet punctuation belongs to chapter 16.

  1. Start every CV achievement with a past action verb: led, organised, managed, designed, raised.
  2. Replace 'Responsible for' with the verb for what you actually did.
  3. Write skills as nouns or -ing phrases in one form: coding, public speaking, video editing.
  4. Write instructions and checklists as commands: complete, sign, attach, post.
  5. In job advertisements, give every duty the same shape, often -ing phrases.
  6. Match within each list; different sections can use different forms.
  7. Check any list by reading only the first word of each line.
You can now use parallel structure in practical writing. CVs, forms, job advertisements, instructions and checklists are lists, and they are scanned by readers with little time. Scanners read the first word of each line. When those words share a shape - led, managed, designed - the list is taken in at a glance. Each kind of list has a usual shape: past action verbs for CV achievements, nouns or -ing phrases for skills, commands for instructions, -ing phrases for duties. The heading and the first item set the shape, and every item should hold it. Common slips are 'Responsible for' in a column of verbs, a skill that turns into a sentence, and a noun phrase in a list of commands. Same-job pairings are still standard; matching them is a choice for the scanning reader. Set the shape, hold it down the column, and read the left edge to check.

Edit for a real reader

The Match Test is the editor's routine at every joint: find where items are joined, name each item's shape, and make them match - unless the pattern is already standard or deliberately broken. Each Craft section names a place where the routine needs extra care.

CheckDraftDecision

deliberate twist (S28)still slow, still crowded and still, somehow, out of samosaskeep - a joke in a light article
closing three (S23, S26)We came as strangers, we worked as partners, we leave as friends.keep

The keeps matter as much as the fixes. Each keep below is a place an over-eager editor might damage the article.

Tempting changeWhy it would be wrong
'to fix, open and give' - cut the repeated 'to''to' repeated for every item and 'to' stated once are both standard; the repeat gives each aim its own weight
'We met ... we listened ... we argued' - cut the repeated 'we'the anaphora gives the paragraph its pulse; repetition here is a technique, not a fault
'new to the job, nervous and a brilliant organiser' - make all three adjectivesa noun phrase beside adjective phrases, all describing Farah, is standard English; the noun lands the praise
'still, somehow, out of samosas' - remove the jokethe article is light-hearted; the 'still' frame holds and the meaning turns on purpose

And the three fixes each break a pattern without gaining anything: a list item with no verb, a loose correlative in edited writing, and a bullet that starts in a different shape from its column.

A good editor leaves a note for every change and for every tempting change not made: 'Kept - anaphora', 'Kept - same-job pairing', 'Fixed - bullet now starts with a verb'. The notes show the writer that the keeps were decisions, not oversights. They also make an editor honest: if a note would say only 'sounded odd', the change probably is not needed.

Picture a piano tuner working through an old piano. She does not tighten every string. She plays each note, listens, and turns the peg only where the note is out of tune. Some notes that sound strange on their own - a deliberately wide chord, a string tuned for a particular piece - she leaves alone, because they are meant to sound that way. When she finishes, the piano sounds like itself, only in tune. Editing for parallel structure is the same: test every joint, adjust only what is out, and leave the character of the piece intact.

Editing a whole text means checking joints at every level: the list inside a sentence, the pair inside a correlative, the column of bullets, and the patterns across paragraphs. A single article can have a matched three in its first line, a broken list in its third and a deliberate twist in its last. The routine does not change from level to level - find the joint, name the shapes, decide - but the reason for keeping or fixing can be different at each one.

Here is where the capstone needs care. First, a keep needs a reason just as a fix does. 'Kept because it sounded fine' is not a reason; 'kept because "to" is repeated for every item, which is standard' is. The reason is what separates a decision from a guess. Second, register decides some verdicts. The loose correlative would be kept in a transcript of a speech or in dialogue. In a written article that is edited before printing, it is fixed. The samosa joke would be removed from a formal report to the governors. In a light article for the school magazine, it stays. The grammar is the same; the purpose of the text changes the answer. Third, some fixes have more than one good version. 'And put a suggestion box in every classroom', 'and placed a suggestion box in every classroom' and 'and installed a suggestion box in every classroom' all restore the verb phrase. What matters is the shape, not the particular verb. The rule through all three: run the Match Test on every joint, decide with the text's purpose in mind, and write one reason for every mark.

Two classmates edit the council's article independently. The first returns it with fourteen changes. She has cut every repeated 'to' and 'we', turned 'a brilliant organiser' into 'brilliantly organised', removed the samosa joke, rewritten the motto as 'we should listen more and we should talk less', and fixed the three real slips. The second returns it with three changes: the long sentence, the correlative and the bullet. Beside the other patterns she has written short notes: 'Kept - anaphora.' 'Kept - same-job pairing.' 'Kept - a joke in a light article.' Surprisingly, both editors found every real slip. Mr Iyer prints the three-change version. The first editor's eleven extra changes each made a correct or deliberate pattern plainer, and together they took the council's voice out of its own article. Editing is restraint as much as correction.

The capstone plants three slips: a long-sentence list item with no verb, a loose correlative in edited written text, and a bullet that breaks its column. Everything else is kept: 'to' repeated for every item, anaphora, a same-job pairing, an antithesis, a deliberate comic turn in a light article, and a closing tricolon. No key contradicts an earlier Craft key: 'to' once or for all is standard, same-job pairings are standard, repetition is never keyed as bad style, and the correlative is tightened only because the text is edited writing for print. The magazine and its readers are invented for the exercise.

  1. Read the whole text once for its purpose and register before marking anything.
  2. Find every joint - and, or, but, correlatives, lists, bullets - and name each item's shape.
  3. Fix an item that changes shape when nothing is gained by the change.
  4. Tighten correlatives in edited written text; leave them in speech and dialogue.
  5. Keep 'to', 'the' and 'we' repeated for every item, same-job pairings and deliberate twists.
  6. Match bullets down the column, even when each line looks fine on its own.
  7. Write one reason beside every fix and every tempting change you chose not to make.
You can now edit a whole text for parallel structure. The council's article held nearly every Craft technique. It repeated 'to' for every aim and 'we' for every clause - both kept. It balanced a motto - 'listen more, talk less' - and closed with a three - 'We came as strangers, we worked as partners, we leave as friends' - both kept. It described Farah as 'new to the job, nervous and a brilliant organiser', a same-job pairing - kept. It bent a pattern for a joke about samosas, in a light article - kept. It also held three slips. A long which-clause hid a list item with no verb: 'and put a suggestion box' fixes it. A loose correlative in edited writing: 'gave us not only longer breaks but also more time'.

What coordination joins

The Match Test asks you to name each item's shape; at Master level you also name each item's job, because coordination is licensed by function as well as form.

CoordinationFormsJob in the sentenceVerdict
bread, milk and eggsnoun phrase x 3all objects of 'bought'like categories: standard

quickly and without a wordadverb + prepositional phraseboth say how she leftunlike categories, one job: standard
the anthem and beautifullynoun phrase + adverbwhat she sang / how she sangtwo jobs: not standard

Two conditions are at work, and they are not equally strict. The table sets them side by side.

ConditionWhat it requiresWho enforces itExample that passesExample that fails
Same functionEach item could fill the shared slot alone and would do the same job thereThe grammar itself: Huddleston and Pullum (2002) state it as a condition on coordinationtired and in a bad moodate lunch and at noon
Same formEach item is the same kind of phraseStyle guides, editors, examiners - the parallel-structure rule of earlier bandstired and hungrycricket, chess and to swim
A pair can pass the grammar and still fail the style rule. 'Rohan likes cricket, chess and to swim' is arguably grammatical - 'likes' accepts a noun phrase or a to-phrase, and each item is its object - yet most editors would change it to 'cricket, chess and swimming' so the list reads as one list. The reverse rarely holds: outside deliberate wordplay such as zeugma, a pairing that fails the function test is not rescued by style.

So the Master reading of the Match Test is layered. Check function first: if the jobs differ, the sentence is broken. Then check form: if the jobs match but the forms do not, decide whether matching them would read better. In a list of three or more, it almost always will.

Picture the shared slot as a socket with a particular shape of job cut into it: 'describes the subject', 'says how', 'receives the action'. Each coordinated item is a plug. Plugs of different brands - a noun phrase, an adjective phrase - can all fit one socket if their prongs match the job. A plug with the wrong prongs does not fit, however similar its casing looks to the others.

The function test runs through the rest of the band. Shared elements and gapping (S32) are what the shared slot looks like when words are left out. Correlative placement (S33) is about where the slot begins. And the legal lists of S37 depend on each item doing the same job, or a clause can be read two ways - which is where a parallel list stops being a matter of taste.

Here is the hard case: 'I like swimming and to run.' Apply the function test. 'I like swimming' - the -ing phrase is the object of 'like'. 'I like to run' - the to-phrase is also the object of 'like'. Same slot, same job. By the condition Huddleston and Pullum describe, the coordination is arguably grammatical, and speakers do produce sentences like it. Yet almost every style guide and editor would change it, and earlier bands of this chapter call it unparallel. Who is right? Both, about different things. The grammar describes what English allows. The parallel-structure rule is a style convention about what reads most clearly: a reader who hears 'swimming' sets up a pattern, and 'to run' breaks it for no reason. When nothing is gained by the mixed forms, matching them is the better choice. Contrast 'He is a doctor and proud of it'. Here there is no single form that says both things well: 'a doctor and a proud one' is clumsy, 'medical and proud of it' changes the meaning. The mixed forms earn their place. That is the Master judgement - not 'mixed forms are wrong', but 'mixed forms need a reason'. The same test explains an early rule of this chapter. In 'Ravi is tall, kind and plays football', the series after 'is' sets up describing items, and 'is plays football' fails the slot - so the series breaks. Join the action to the whole verb phrase instead and it is fine: 'Ravi is tall and kind, and plays football' pairs two verb phrases, 'is tall and kind' and 'plays football'. The fault was never the action; it was where the action was joined.

Some of the most natural sentences in English coordinate unlike categories, and nobody notices. 'You can pay now or when you collect it.' (adverb + clause, both saying when) 'Is she upstairs or in the garden?' (adverb + prepositional phrase, both saying where) 'He is Welsh and a keen singer.' (adjective + noun phrase, both describing him) Force any of these into matching forms and it gets worse: 'You can pay at the present moment or at the time of collection' is stiffer and no clearer. The reverse surprise: two items of exactly the same form can still clash. 'She left in a hurry and in a taxi' joins two prepositional phrases, but one says how and one says by what means, and many readers hear a slight joke in it - a figure called zeugma when the effect is deliberate. Same form does not guarantee same job.

This section summarises one condition from a very long treatment of coordination. Huddleston and Pullum's 'The Cambridge Grammar of the English Language' (2002) discusses many further cases, including coordinations that are acceptable only in some positions; the sentences here are illustrations, not quotations from the book. Other frameworks describe the same facts differently. The judgement that 'I like swimming and to run' is grammatical but unparallel is a reasonable reading of the function test, not a settled verdict, and some speakers find it awkward on grammatical grounds too.

  1. Name each item's job in the shared slot before you name its form.
  2. If the jobs differ, rewrite: the coordination is broken.
  3. If the jobs match and the forms match, leave it alone.
  4. If the jobs match and the forms differ, ask whether matching forms would read better; in lists of three or more it usually will.
  5. Keep pairs like 'a doctor and proud of it' and 'quickly and without a word' - they are standard.
  6. When you defend a mixed-form pair, name the shared function and credit the framework.
  7. Say 'unparallel' for a style fault and 'ungrammatical' only when the function test fails.
Coordination joins items that fill the same slot. The default case is like categories: noun phrase with noun phrase, clause with clause, adjective with adjective. This is what earlier bands called parallel structure, and in lists it remains the best rule. Huddleston and Pullum (2002) describe a wider condition: items of unlike categories may be coordinated when each could fill the shared slot alone with the same function. 'A doctor and proud of it' works because both items describe him after 'is'. 'Quickly and without a word' works because both say how she left. 'The anthem and beautifully' fails because one is the object and the other says how. That gives the Match Test two layers. Function first: different jobs mean a broken sentence. Form second: same jobs with different forms is grammatical, and an editor decides whether matching would read better. Mixed forms are not wrong; they need a reason.

Shared elements and ellipsis

The Match Test ends with the drop test; here it is applied to every word the items share, stated or left out.

SentenceWhat is sharedDrop testVerdict
interested in and good at physics'physics'interested in physics / good at physicsfits both: standard
to read, write and debate'to'to read / to write / to debatefits all: standard

has never and will never forget'forget'has never forget / will never forgetfails one: write 'has never forgotten and will never forget'
old men and women'old'?old men / old women? or women?ambiguous: say which

Shared elements come from three places in the sentence. Each has its own typical fault.

Where the shared word sitsExampleTypical faultRepair
Before the items (a shared start)to swim, run and cycle; the old men and womena half-repeated little word ('to swim, run and to cycle'); a modifier whose reach is unclearstate it once or repeat it for all; repeat or reorder to fix scope
After the items (a shared end)interested in and good at physicsthe end fits only one item ('interested and good at physics')give each item its own linking word: 'interested in and good at'
Inside a later clause (gapping)Rahul teaches maths and Anita sciencethe gapped verb or auxiliary does not fit ('The window was broken and the doors smashed')restore the word in the right form: 'and the doors were smashed'
Gapping needs parallel remnants. 'Rahul teaches maths and Anita science' works because 'Anita science' mirrors 'Rahul maths'. Break the mirror - 'Rahul teaches maths and on Tuesdays' - and the reader cannot rebuild the second clause.

The shared-auxiliary case divides usage guides. Many careful writers accept 'The rice was cooked and the vegetables steamed' in informal prose; formal editing usually restores 'were', because the shared 'was' fails the drop test.

Picture each shared word as a lamp hanging over a row of items. Its light must fall on every item it serves - and each item must look right in that light. 'Physics' hangs at the end of the row and lights 'interested in' and 'good at' equally. 'Forget' lights 'will never' well and 'has never' badly. 'Old' hangs at the start of 'old men and women', and the reader cannot tell how far its light reaches.

Shared elements turn up again in the next section: correlatives such as 'either ... or' mark exactly where the shared part ends and the matched items begin. In law and technical writing (S37), a shared modifier with unclear scope is one of the classic ways a list can be read two ways - and so a clause can be argued over by two parties who each read it their own way.

The hard case is scope, because both readings are grammatical. 'The scheme is open to old men and women.' Reading one: 'old' covers both - old men and old women. Reading two: 'old' covers only the men - old men, and women of any age. Nothing in the grammar decides. Readers use context: a pension scheme suggests reading one; a community centre's list of groups might suggest reading two. The fixes are mechanical once you know which reading you mean. To make 'old' cover both: repeat it ('old men and old women') or group the nouns explicitly ('men and women who are old'). To make 'old' cover only the men: reorder so the modifier cannot reach ('women and old men') or add a determiner that breaks the shared start ('the old men and the women'). The same problem appears after the items. 'Books and journals published after 2020' - are the books recent too? Again, repeating ('books published after 2020 and journals published after 2020') or reordering ('journals published after 2020, and books') settles it. The Match Test adds one question here: how far does the shared word reach?

Comparisons hide one of the most interesting ambiguities in English, and it comes from the same kind of left-out words. 'Priya likes Anil more than Ravi.' This can mean 'more than Ravi likes Anil' or 'more than she likes Ravi'. The words after 'than' are the remnant of a clause, and the reader has to decide what was left out. Adding one word settles it: 'more than Ravi does' or 'more than she does Ravi'. And gapping can be read the wrong way even when it is grammatical. 'Meena met Kabir on Monday and Arjun on Friday' most naturally means Meena met Arjun on Friday. But it could mean Arjun met Kabir on Friday. Parallelism usually steers the reader to the first reading - the remnants 'Arjun on Friday' line up with 'Kabir on Monday' - which is exactly why matching structure matters.

Gapping has further conditions this section does not cover; the examples here keep to simple two-clause cases joined by 'and'. Judgements on shared auxiliaries ('was broken and the doors smashed') vary: many readers accept them in informal prose, and the section keys the restored form only for formal writing. The comparison 'as good or better than' is very common in speech; the full form 'as good as or better than' is keyed only where a formal register is stated.

  1. List every word that is stated once but serves several items.
  2. Read each item alone with its shared word attached; repair any that fail.
  3. Give each item its own preposition when the prepositions differ: 'interested in and good at'.
  4. Give each helper verb its own main-verb form: 'have never lied and will never lie'.
  5. In formal writing, restore a gapped auxiliary that would not agree.
  6. Check the reach of every shared modifier; repeat it or reorder to make the reach clear.
  7. Gap a verb only when the remnants mirror the first clause.
Parallel structure lets words be stated once and shared. A shared start ('to', 'the', a modifier like 'old') reaches forward over the items. A shared end ('physics' in 'interested in and good at physics') reaches back. A gapped verb ('I ate rice and Ravi bread') is left out of a later clause and supplied by the reader, which works only when the remnants mirror the first clause. The drop test checks every share: read each item alone with the shared word attached. 'Has never and will never forget' fails one item; 'interested and good at physics' fails one item; 'The window was broken and the doors smashed' fails agreement in formal writing. Each repair gives the odd item its own word. Scope is the second risk. 'Old men and women' is grammatical in two readings. Repeat the modifier to make it reach both items, or reorder to stop it reaching the second. The Match Test now asks two questions of every shared word: does it fit, and how far does it reach?

Correlatives and focus

The Match Test's first step is to find the joint; with a correlative, both halves of the pair are the joint, and each must be followed by the same shape.

PlacementSentenceAfter the first halfAfter the second halfRegister
tightShe plays not only the sitar but also the tabla.noun phrasenoun phraseany, and expected in formal writing
looseShe not only plays the sitar but also the tabla.verb phrasenoun phrasecommon in speech and informal writing
tightYou can pay either now or later.adverbadverbany
looseYou can either pay now or later.verb phraseadverbcommon in speech
fronted, invertedNot only did she win, but she also broke the record.clause (inverted)clauseany; the inversion is required

Placement is not only a matter of tidiness. It tells the reader what is being added or contrasted - the focus.

PlacementWhat follows each halfFocus: what is added
Anil not only reads Urdu poetry but also writes it.verb phrase / verb phrasea second action
Anil reads not only Urdu poetry but also Persian poetry.noun phrase / noun phrasea second kind of poetry
Not only Anil but also his sister reads Urdu poetry.noun phrase / noun phrasea second reader
Anil not only reads Urdu poetry but also Persian.verb phrase / noun phraseunclear until the end: a second action is expected, an object arrives
Usage guides differ on the last row. The stricter tradition treats it as faulty parallelism and always tightens it. Descriptive usage guides observe that loose placement is common in edited prose and that readers seldom misunderstand it. A defensible policy sits between: tighten in formal writing, where the reader should never have to reread; leave loose placement alone in speech, dialogue and informal notes.

Inversion is a separate matter. When 'not only' or 'neither' begins a clause, standard English puts the auxiliary before the subject: 'Not only did she win', 'Neither does he'. That is not a style preference - 'Not only she won' is not standard in any register.

Think of a correlative as a pair of spotlights on a stage. Each spotlight must fall on the same kind of performer: two dancers, or two singers. Where you place the first spotlight tells the audience who the act is about. In a loose placement the first light falls on a dancer and the second on a drum - the audience follows, but blinks. In formal writing, you aim both lights before the curtain goes up.

Correlatives are the most visible parallel frame in English, and rhetoric builds on them. The antithesis of the next section ('not ... but ...') is a correlative used for persuasion, and the careful placement practised here is what makes a balanced line balance. In legal drafting (S37), 'either ... or' and 'both ... and' mark exactly which items a condition covers.

The hard question is when loose placement actually misleads. Most of the time it does not. 'She not only plays the sitar but also the tabla' is understood at once, because the tabla can only be something she plays. But consider a sentence where the second half could attach in two places. 'The committee will either review the budget or the staffing plan by Friday.' Is the choice between reviewing the budget and reviewing the staffing plan? Or between reviewing the budget and doing something else with the staffing plan? Here the reader almost certainly lands on the first reading, but only after a moment. In a contract or a set of instructions, that moment is a cost. Now consider focus. 'Riya not only wrote the play but also directed it' focuses on actions. 'Riya wrote not only the play but also the music' focuses on things written. If the writer means the second and writes 'Riya not only wrote the play but also the music', the reader first expects a second action, then gets an object: a small garden-path. In formal writing, the Master policy is to place the first half exactly where the contrast begins, so that the reader's first guess is the right one.

Inversion after a fronted negative is not special to 'not only'. English does it after a whole family of negative and restrictive openers. 'Never have I seen such rain.' 'Rarely does the train leave on time.' 'Neither did his brother.' 'Only then did she understand.' In each case the auxiliary jumps in front of the subject, exactly as it does in a question. Move the opener back into the sentence and the inversion disappears: 'I have never seen such rain.' That is why 'Not only she won' feels wrong to most readers even though every word is ordinary. It is not a parallelism fault at all - the two halves may match perfectly - but a word-order fault triggered by where 'not only' stands.

Usage guides are described here in general terms; they differ in detail, and some accept loose placement more readily than this section's formal policy does. The section keys tight placement only where a question names a formal or written register, and never marks loose placement in speech as an error. Inversion after fronted 'Not only' is treated as standard grammar; agreement with 'either ... or' and 'neither ... nor' subjects belongs to the agreement chapter and is not tested here.

  1. Underline what follows each half of a correlative; the two shapes should match.
  2. In formal writing, slide the first half along until it stands where the contrast begins.
  3. Repeat a preposition after both halves, or move the first half in front of it: 'both in Pune and in Chennai', 'in both Pune and Chennai'.
  4. After a fronted 'Not only' or 'Neither', put the auxiliary before the subject.
  5. In formal writing keep both halves: 'not only ... but also', 'either ... or'.
  6. Leave loose placement alone in speech, dialogue and informal notes.
  7. When you tighten, check that the focus you create is the focus you mean.
Correlatives come in pairs - either/or, neither/nor, both/and, not only/but also, whether/or - and each half should be followed by the same shape. Tight placement ('plays not only the sitar but also the tabla') matches the shapes exactly. Loose placement ('not only plays the sitar but also the tabla') is common in speech and in much published writing, and it rarely misleads. Usage guides differ on how strictly to require the tight form; a defensible policy is to tighten in formal writing and leave speech alone. Placement also marks focus: put 'not only' before a verb to add an action, before an object to add a thing, before a subject to add a person. When the first half is placed loosely, the reader may expect one kind of addition and get another. When 'not only' or 'neither' begins a clause, English inverts the subject and auxiliary: 'Not only did she win'. That is grammar, not style. The Match Test now adds a register check before any correlative is called faulty.

Classical figures of parallelism

Every classical figure of parallelism passes the Match Test - matching members after a joint - and then adds one extra pattern.

FigureGreek meaningPatternExample
isocolonequal membersmembers of the same length and shapeVeni, vidi, vici.
tricolonthree membersthree parallel membersof the people, by the people, for the people

antithesisa setting againstopposite ideas in matching framesthe best of times ... the worst of times
chiasmusa crossing, like the letter Xterms repeated in reverse order: A B, B AFair is foul, and foul is fair

The figures are tools, and each does a different job for a listener.

FigureWhat it doesPublic-domain instance
isocolongives a line a steady beat that is easy to rememberVeni, vidi, vici (as reported by Plutarch and Suetonius)
tricolonfeels complete; three is the smallest number that makes a pattern and closes itLincoln, Gettysburg Address (1863)
anaphorabuilds momentum; each new member is announced by the same openingEcclesiastes 3, King James Bible (1611)
epistrophehammers the key idea by ending on it again and again1 Corinthians 13:11, King James Bible
antithesissharpens a contrast by holding everything else equalDickens, A Tale of Two Cities (1859); Brutus in Julius Caesar
chiasmusturns an idea round so the listener sees it from the other sideMacbeth; Mark 2:27, King James Bible
Most of the names are Greek, and Aristotle's Rhetoric already discusses antithesis and balanced clauses. Latin handbooks such as the Rhetorica ad Herennium and Quintilian's Institutio Oratoria describe the figures too, often under Latin names - the Ad Herennium calls anaphora repetitio and epistrophe conversio. When the same words come back reversed, chiasmus is also called antimetabole.

Figures combine freely. 'Of the people, by the people, for the people' is a tricolon, an isocolon and an epistrophe at once. Name every figure you can defend, and say which one carries the effect you are describing.

Picture a row of matching arches - that is parallel structure. Isocolon makes the arches the same width; tricolon builds three of them. Anaphora carves the same keystone at the start of each arch; epistrophe carves it at the end. Antithesis paints one arch light and its twin dark. Chiasmus is the X you draw when you join the first arch's left stone to the second arch's right.

The classical names were given by Greek and Roman teachers, but the patterns are far older and far wider. The next section turns to ancient Hebrew poetry, where parallel lines are the building principle of whole books, and S36 finds matching structures in Chinese couplets and Sanskrit and Hindi verse. Close reading in S39 asks you to name these figures in longer passages.

Here is the hard case: a famous line from a speech that is still under copyright. In his inaugural address of January 1961, President John F. Kennedy urged Americans not to ask what their country could do for them, but to ask what they could do for their country. That is a paraphrase, and the right way to handle the line in writing: the speech was published in the 20th century, and a close reading can describe it without reproducing it. What figure does it use? The terms 'your country' and 'you' appear in one order in the first half and in reverse order in the second - A for B, then B for A. That is chiasmus; because the same words return, some writers call it antimetabole. It is also antithesis: 'ask not ... but ask' sets two opposite requests in matching frames. The effect comes from the reversal. The listener hears the familiar direction of help - from state to citizen - and then hears it turned round. The parallel frames make the turn impossible to miss. The Master move is to name both figures, show the reversal in a paraphrase, and explain why the reversal persuades - without quoting a word you are not sure of or not free to use.

One line can hold three figures at once, and the most famous lines usually do. 'It was the best of times, it was the worst of times.' Anaphora: both members open with 'it was the'. Antithesis: 'best' and 'worst' are opposites in matching slots. Isocolon: the two members have the same length and shape, word for word. Dickens goes on, in A Tale of Two Cities (1859), with a long run of such pairs, so the opening becomes a pattern the reader learns to expect. And the X of chiasmus hides in unexpected places. 'The sabbath was made for man, and not man for the sabbath' (Mark 2:27, King James Bible) reverses 'sabbath' and 'man' - and, like 'I ate rice and Ravi bread' in S32, leaves the verb out of the second half. Ellipsis and chiasmus work together: the gap makes the reversal quicker and sharper.

The Greek meanings given are the usual glosses of each term; ancient and modern writers do not always use the names in exactly the same way, and some count a figure only when its members are strictly equal. The attributions to Aristotle, the Rhetorica ad Herennium and Quintilian are general, not quotations. 'Veni, vidi, vici' is reported by ancient writers, not preserved in Caesar's own hand. The Kennedy address is paraphrased because it is not in the public domain.

  1. Count the members and compare their shapes before naming any figure.
  2. Box every repeated word and note whether it falls at the start, at the end, or in reverse.
  3. Name every figure a line supports, and say which one drives the effect you are discussing.
  4. Distinguish antithesis (different terms, same order) from chiasmus (same terms, reversed).
  5. Quote public-domain texts word for word, or not at all.
  6. Paraphrase 20th-century speeches and describe their structure instead of quoting.
  7. Always pair the name with its effect on the listener.
Six classical figures are parallel structure with a purpose. Isocolon matches the length and shape of members; tricolon builds three of them. Anaphora repeats the opening of each member; epistrophe repeats the ending. Antithesis sets opposite ideas in matching frames. Chiasmus repeats terms in reverse order, A B then B A, and is called antimetabole when the very same words return. The names are mostly Greek. Aristotle's Rhetoric discusses antithesis and balanced clauses, and Latin handbooks such as the Rhetorica ad Herennium and Quintilian describe the figures under Latin and Greek names. Famous lines usually combine figures: 'It was the best of times, it was the worst of times' is anaphora, antithesis and isocolon together. A Master analysis names every figure it can defend, shows the pattern in the words, explains the effect, and paraphrases any line not in the public domain.

Parallelism in ancient texts

The Match Test works on whole lines here: find the joint between two lines, match their parts term by term, and name how the second answers the first.

Lowth's typeSecond line...King James Bible exampleTerm-by-term match
synonymousechoes the first in new wordsThe heavens declare the glory of God; and the firmament sheweth his handywork. (Psalm 19:1)heavens / firmament; declare / sheweth; glory of God / handywork
antitheticstates the oppositeA soft answer turneth away wrath: but grievous words stir up anger. (Proverbs 15:1)soft answer / grievous words; turneth away / stir up; wrath / anger
syntheticcompletes or builds on the firstTrain up a child in the way he should go: and when he is old, he will not depart from it. (Proverbs 22:6)the training / its lasting result

Lowth's three types were a breakthrough, and they are still the standard starting point. Later scholarship asked a sharper question: is the second line ever really the same as the first?

Lowth (1753)Later view: James Kugel (1981), Robert Alter (1985)
What parallelism isa correspondence between lines, sorted into three typesa relation in which the second line usually takes the first further
Synonymous linessay the same thing twicerarely identical: the second line often narrows, heightens or makes concrete
Synthetic linesa third type for lines that build on the firsta catch-all; most couplets 'build' in some way
How to read a coupletidentify the typeask what the second line adds - 'A, and what's more, B'
Try it on Psalm 24:1: 'The earth is the LORD's, and the fulness thereof; the world, and they that dwell therein.' Lowth would call it synonymous. The later reading notices that the second line moves from the earth and what fills it to the world and the people who live in it - a step from land to inhabitants. Both readings match the terms; the second also asks what changes between them.

Use Lowth's names as labels and the later question as analysis. An answer that does both is precise and current.

Picture a couplet as two steps of a staircase. Lowth measured the steps and sorted them: a step at the same height (synonymous), a step down on the other side (antithetic), a step that carries you onward (synthetic). The later reading adds a spirit level: even steps that look the same height usually rise a little, and that small rise is where the poetry is.

Hebrew parallelism shows that matching structure can organise whole books of poetry, not just single sentences. The next section finds related principles in other traditions - the paired lines of Chinese couplets and the balanced halves of Sanskrit and Hindi verse and proverbs - and S39 returns to the King James Bible for close reading of longer passages.

Here is the hard case: a couplet that fits two of Lowth's types. 'The LORD is my shepherd; I shall not want.' (Psalm 23:1) Is this synonymous? The lines do not echo each other term by term: 'the LORD' does not pair with 'I', and 'shepherd' does not pair with 'want'. Is it antithetic? Nothing is opposed. So Lowth's scheme puts it in the synthetic type - the second line draws a consequence from the first: because he is my shepherd, I lack nothing. But that is exactly the kind of case that led later scholars to question the scheme. If 'synthetic' covers every couplet that is not an echo or an opposite, it describes very little. Kugel's alternative - 'A, and what's more, B' - fits this line directly: the first line states a relationship; the second line draws out what it means for the speaker. The Master answer uses both. It classifies ('synthetic, in Lowth's terms'), then analyses ('the second line turns an image into a consequence'), and notes where the classification strains. Frameworks are tools. The best analysis says which tool it is using and where the tool stops fitting.

Parallelism of meaning survives translation in a way rhyme and metre usually do not. A rhyme belongs to the sounds of one language; translate 'Twinkle, twinkle, little star, how I wonder what you are' into Hindi and the rhyme is gone unless the translator builds a new one. But the pairing in 'The heavens declare the glory of God; and the firmament sheweth his handywork' is a pairing of ideas - heavens with firmament, glory with handywork - and it comes through into English intact, many centuries after it was composed and in a language with a different grammar and sound system. That is why readers of the Psalms in English, Hindi, Tamil or Swahili can all hear the balance of the lines. It is also why the cadence of the King James Psalms has shaped so much English prose and oratory: the parallel structure was carried across even when every word changed.

This section simplifies a large field. Lowth's lectures, and later scholarship by James Kugel ('The Idea of Biblical Poetry', 1981) and Robert Alter ('The Art of Biblical Poetry', 1985), are summarised in a sentence each; their full arguments are more detailed, and they are not the only scholars in the debate. The King James Bible (1611) is quoted because it is in the public domain; its wording is a translation, and scholars disagree about the metre of the Hebrew originals. Verse references follow the King James numbering.

  1. Split each verse at its main pause and set the two lines one above the other.
  2. Join each term to its partner before naming any type.
  3. Use Lowth's labels - synonymous, antithetic, synthetic - and credit them to him (1753).
  4. Then ask what the second line adds: a sharper word, a narrower focus, a consequence.
  5. Note where a couplet strains the three types instead of forcing it.
  6. Quote a public-domain translation word for word, with its reference.
  7. When you write balanced lines of your own, let the second line go one step further.
Biblical Hebrew poetry is built on parallel lines. Robert Lowth, in his lectures De Sacra Poesi Hebraeorum (1753), called the pattern parallelismus membrorum and sorted it into three types. Synonymous: the second line echoes the first ('The heavens declare the glory of God; and the firmament sheweth his handywork'). Antithetic: it opposes the first ('A soft answer turneth away wrath: but grievous words stir up anger'). Synthetic: it completes or builds on the first ('Train up a child in the way he should go: and when he is old, he will not depart from it'). Later scholars, among them James Kugel and Robert Alter, argued that the second line rarely just repeats; it usually intensifies, narrows or advances - 'A, and what's more, B'. The Match Test serves both views: split the verse, join each term to its partner, name the relation, then say what the second line adds. Because the parallelism is of meaning, not sound, it survives translation.

Parallelism across languages

The Match Test works across languages: find the joint between the two halves, name the shape of each part, and check what the tradition asks to match.

SlotFirst lineSecond lineWhat matches
1-2白日 bái rì 'white sun'黄河 Huáng Hé 'Yellow River'colour + noun: a thing in nature
3依 yī 'lean on, go along'入 rù 'enter'verb of movement
4山 shān 'mountain'海 hǎi 'sea'noun: a landform
5尽 jìn 'come to an end'流 liú 'flow'verb; traditionally the first line ends on an oblique tone, the second on a level tone

Different traditions match different things. The table compares four.

TraditionExample (glossed in this section)What is matched
Chinese duilianBái rì yī shān jìn, / Huáng Hé rù hǎi liú.length, word class slot by slot, meaning category; tones contrast
Sanskrit versekarmaṇy evādhikāras te / mā phaleṣu kadācana (Bhagavad Gita 2.47)two half-lines of the metre, set against each other in meaning: action / its fruits
Hindi proverbs and coupletsJaisī karnī, / vaisī bharnī.two short halves with matching shape and a matching sound pattern
English proverbsOut of sight, / out of mind.two phrases of the same shape, often with a word repeated
Hindi builds parallelism into its grammar with relative-correlative pairs: jo ... vo ('who ... that one'), jaisā ... vaisā ('as ... so'), jitnā ... utnā ('as much ... that much'). 'Jitnā paṛhoge, utnā sīkhoge' - 'The more you read, the more you will learn' - matches clause to clause exactly as its English translation does.

Across all four, the principle is the one the Match Test names: find the joint, match the shapes. What changes is how much each tradition asks to match - meaning alone, or meaning, word class and sound together.

Picture the two lines of a couplet as the two leaves of a door. In Hebrew poetry the leaves are carved with matching scenes. In a Chinese duilian they must also be the same height, with every panel on the left facing a panel of the same kind on the right - and painted in contrasting colours of sound. In a Hindi proverb the leaves are small and close together, and they swing on one hinge: jaisī on one side, vaisī on the other.

Having seen parallelism as a principle of poetry in several languages, the band turns to prose that has no interest in beauty at all. S37 looks at law and technical writing, where matching the items in a list is not about rhythm but about making sure a rule or a specification can be read only one way - by a judge, an engineer or a customer who was never in the room when it was written.

The hard case is deciding what counts as a match when two languages build phrases differently. Take the Kabir couplet 'Kāl kare so āj kar, āj kare so ab.' Glossed: kāl 'tomorrow', kare 'would do', so 'that', āj 'today', kar 'do!'; then āj 'today', kare 'would do', so 'that', ab 'now'. The meaning: what you would do tomorrow, do today; what you would do today, do now. The halves are parallel, but not symmetrical. The second half leaves out the final 'kar' - a gap of the kind S32 calls gapping, and the reader supplies it. The time words step forward in a chain - tomorrow to today, today to now - so 'āj', the last time word of the first half (only 'kar' follows it), begins the second - close to the figure rhetoric calls anadiplosis. So is it a match? In meaning and in frame (X kare so Y), yes. In length, no: the second half is shorter. The Master answer does not force a yes or no. It names what matches - the frame, the grammar, the time-chain - and what the gap does: it makes the second half quicker, as if the couplet is already hurrying to 'now'.

Some of the tightest parallelism in the world is pasted on doors every year. A common Spring Festival couplet reads: 'Tiān zēng suìyuè rén zēng shòu; chūn mǎn qiánkūn fú mǎn mén.' Glossed: tiān 'heaven', zēng 'adds', suìyuè 'years and months', rén 'people', zēng 'add', shòu 'long life'; chūn 'spring', mǎn 'fills', qiánkūn 'heaven and earth', fú 'good fortune', mǎn 'fills', mén 'the home' (literally 'door'). 'Heaven adds years, people add long life; spring fills the world, fortune fills the home.' Each line has seven characters, and each is itself a small parallel pair: noun-verb-noun, noun-verb-noun. The two lines then match each other slot by slot. It is parallelism inside parallelism - and it is not the work of a famous poet, but a line many families hang up every year.

The rules of duilian are summarised generally here; the tradition has many refinements, and tonal rules are described only in outline (level versus oblique tones, with the traditional pattern of an oblique-tone ending for the first line and a level-tone ending for the second). Glosses are simplified word-by-word renderings for analysis, not literary translations. Transliterations use common conventions (pinyin for Chinese; a simplified scheme for Sanskrit and Hindi). The Kabir couplet is traditionally attributed to him, as many sayings are.

  1. Gloss every word of a non-English line before you analyse it.
  2. Count and match in the original language, not in the translation.
  3. Say which features the tradition matches: length, word class, sound, meaning.
  4. Use the term duilian only for the Chinese form and its rules.
  5. Look for grammatical frames that are parallel by design, such as jitnā ... utnā.
  6. Note gaps and chains, as in the Kabir couplet, instead of forcing symmetry.
  7. Use only examples you can translate with confidence, and credit their source or tradition.
  8. Compare with an English line of similar shape to make the analysis concrete for your reader.
Parallelism runs through many languages, and each tradition matches something slightly different. A Chinese duilian's two lines traditionally match in length and in word class slot by slot, pair related meanings, and contrast in tone: 'Bái rì yī shān jìn, Huáng Hé rù hǎi liú' matches white sun with Yellow River, mountain with sea. Sanskrit verse sets half-lines against each other: 'karmaṇy evādhikāras te / mā phaleṣu kadācana' opposes action and its fruits. Hindi proverbs pair short matching halves ('Jaisī karnī, vaisī bharnī'), and Hindi grammar offers relative-correlative frames (jitnā ... utnā) that mirror English 'the more ..., the more ...'. A couplet attributed to Kabir shows parallel halves with a gap and a chain of time words. The Match Test works in every case: find the joint, name the shapes, and say which features are matched - after glossing every word.

Parallelism in law and technical writing

The Match Test's drop test becomes the lead-in test: read the introducing words in front of each item, and every item must complete them.

Lead-inItemsLead-in testVerdict
The supplier shalldeliver within ten days / replace faulty parts free of charge / invoice the buyer monthlyshall deliver / shall replace / shall invoiceparallel: every item is a verb phrase
The supplier shalldeliver within ten days / replacement of faulty parts / the buyer is invoiced monthlyshall replacement? / shall the buyer is?unparallel: two items do not complete the lead-in
The policy coverscars and vans owned by the companycovers cars (owned by the company?) / covers vans owned by the companyambiguous scope
The policy coversvans owned by the company, and carsthe modifier cannot reach 'cars'clear: only the vans must be owned

Unparallel lists create three kinds of trouble in rules and specifications. Each has a standard repair.

TroubleExample (written for this section)What a reader cannot tellRepair
An item breaks the lead-inMembers must pay dues, attend meetings and no smoking in the hall.whether the third item is an obligation on members or a general ban'...and must not smoke in the hall'
A modifier's reach is unclearThe discount applies to students and senior citizens with a valid card.whether students need the cardrepeat ('students with a valid card and senior citizens with a valid card') or regroup ('students and senior citizens, each with a valid card')
A dropped linking wordSection 4 applies to employees who work at night or handle chemicals.usually clear; but in a longer list the second clause may seem to start a new rulerepeat 'who': 'who work at night or who handle chemicals'
Interpreters have long faced lists like these. In some legal systems, readers of statutes and contracts apply general presumptions: one, often called the rule of the last antecedent, reads a trailing modifier as reaching only the nearest item; another, sometimes called the series-qualifier presumption, reads it as reaching every item in a tight parallel list. Which applies depends on context - which is exactly why careful drafters do not leave it to a presumption.

In specifications the rule is simpler: one requirement per item, each a complete, parallel statement ('The pump shall start within five seconds'), so that each can be tested and passed or failed on its own.

Picture the lead-in as a stamp and each item as a sheet of paper fed under it. Every sheet must come out as a complete sentence: 'shall deliver', 'shall replace', 'shall invoice'. A sheet that comes out as 'shall replacement' is a misprint. A modifier at the end of the list is a second stamp: before you press it, you must decide which sheets are in the tray.

Law and technical writing show parallelism at its most practical. The next section turns to a different kind of reader - an examiner - and to the error-spotting and sentence-improvement items that test parallel structure, including the both-standard cases that careful items avoid keying. The lead-in test you used here is the fastest tool you will take into that exam hall.

Here is the hard case: a list that is perfectly parallel and still ambiguous. 'The grant may be used for travel, accommodation and equipment purchased in India.' Every item is a noun phrase; every item completes 'may be used for'. The Match Test's form check passes. But 'purchased in India' sits at the end, and its reach is unclear. Must the travel be bought in India? The accommodation? Or only the equipment? This is where the two interpretive presumptions come apart. Read with the last-antecedent presumption, only the equipment must be bought in India. Read with the series-qualifier presumption, the modifier reaches all three, because the list is tight and parallel. Each reading is defensible, and a grant officer and an applicant could each pick the one that suits them. The drafter's fix depends on the intended meaning. To restrict only the equipment: 'for travel, for accommodation, and for equipment purchased in India' - the repeated 'for' marks three separate items, and the modifier stays with the last. To restrict all three: 'for the following, if purchased in India: travel, accommodation and equipment' - the condition moves in front, where it plainly covers everything after it. The Master lesson: parallel form is necessary for clarity, but not sufficient. The Match Test must also ask how far each shared word reaches.

Technical writers often use a list format that is parallel by design: every item begins with the same kind of word. 'To reset the router: unplug the power cable; wait thirty seconds; plug the cable back in; wait for the green light.' Every step begins with an imperative verb. That is not decoration. A reader following the steps with one hand on the router can find the next action at a glance, because it is always the first word. Requirement documents go further. Many engineering teams write every requirement in the same frame - '[The system] shall [verb] [object] [condition]' - so that a reviewer can scan a hundred requirements and spot at once the one that has no verb, two verbs, or no testable condition. A frame that would be monotonous in an essay is exactly what makes a specification checkable.

All rules, clauses and specifications in this section were written for it; no real cases, statutes or contracts are quoted or described. The two interpretive presumptions are described in general terms: they are applied differently in different legal systems and contexts, and this section is not legal advice. Whether 'and' or 'or' ends a legal list is a question of meaning, not parallel structure, and is not tested here; nor is list punctuation, which belongs to Chapter 16.

  1. Isolate the lead-in and read it in front of every item.
  2. Make every item the same kind of phrase, and every duty a duty of the same party.
  3. Put one requirement in each item, stated so that it can be tested.
  4. Check the reach of every modifier at the start or end of a list.
  5. To limit a modifier to one item, reorder or repeat the linking word before each item.
  6. To extend a modifier to all items, move it in front of the list.
  7. Repeat 'who', 'that', 'by' or 'for' whenever it removes a second reading.
  8. Prefer clarity to rhythm; a longer sentence that can be read one way is better.
In law and technical writing, parallelism is a tool for removing doubt. Every item in a list must complete its lead-in: 'The supplier shall deliver / replace / invoice'. An item that breaks the lead-in ('and no smoking in the hall') leaves a reader unsure whether it is an obligation at all. The lead-in test - the drop test with a name - finds such items. Modifier scope is the second risk. 'Cars and vans owned by the company' has two readings. Some legal systems use general presumptions to decide such cases, which can point in opposite directions, so careful drafters decide for the reader: repeat the modifier, reorder the list, repeat the linking word, or move the condition in front. Specifications carry the principle furthest: one requirement per item, each in the same frame, each testable on its own. The Match Test here asks three questions: does each item complete the lead-in, how far does each modifier reach, and is each item one thing?

Parallel structure under exam conditions

Every item type below is answered by the Match Test: find the joint, name each item's shape, make them match - and check the fix changes nothing else.

Item type (described generally)What you are shownTypical fault plantedFast move
Error spottinga sentence divided into parts, plus a 'No error' optionthe last item in a different form: 'painting, singing and to dance'name the form of every item; the odd one is the error
Sentence improvementa marked part and several replacements, one being 'no change'a half-repeated little word: 'to warm up, to stretch and drink water'choose the replacement that matches and keeps the meaning
Choose the best versionfour full versions of one sentenceunbalanced comparison: 'cooler than Delhi'check that like is compared with like
Transformationa sentence to rewrite from a given opening'Begin with Not only'invert after the opening; match both halves

Careful items avoid keying constructions that careful writers disagree about. You should avoid 'correcting' them too.

ConstructionWhy it is standardWhat a careful item does
to travel, read and rest / to travel, to read and to rest'to' stated once for all, or repeated for eachkeys only the half-repeat: 'to travel, read and to rest'
a doctor and proud of itunlike forms, one job (S31)never keys it as an error; 'No error' is correct
She not only plays the sitar but also the tabla.loose placement, common in speech (S33)keys tight placement only when the stem names formal writing
as good as or better than / as good or better thanthe short form is common in speech (S32)keys the full form only in a formal context
A useful habit: when an option looks different from the original but you cannot name a fault in the original, choose 'No error' or 'No improvement'. Items are built around one nameable fault. If you cannot name it, it is probably not there.

A second habit guards against a common trap. Parallel versions are often shorter, so a test-wise candidate may simply pick the shortest option. Sometimes that works; sometimes the shortest option matches the forms but drops a word the meaning needs. Always read the chosen option in the full sentence.

Picture the item as a row of beads on a string, with the options as replacement beads. Your job is not to find the prettiest bead, but the one that matches its neighbours in shape and does not change the colour of the necklace. And sometimes the row already matches: then the right move is to put the replacement beads down.

Exam items test the same knowledge as every earlier section, compressed into single sentences under time pressure. The next section does the opposite: it gives you long public-domain passages and time to read them closely, asking what the parallelism is doing, not only whether it is correct - the question an examiner never has room to ask in one sentence.

Here is the hard case: two options that both fix the parallelism. Original: 'The new policy is fair, simple and it saves money.' Option one: 'fair, simple and economical'. Option two: 'fair, simple and money-saving'. Both replace a clause with an adjective, so both match. Which is the answer? Apply three further checks, in order. Meaning: does each keep the sense of 'it saves money'? 'Economical' does; 'money-saving' does too. Register: which fits a formal sentence? 'Economical' is the more usual formal word; 'money-saving' is more informal. New errors: does either introduce one? Neither does. A well-built item would not offer both - it would include only one matching option, precisely because the choice between them is a matter of style. If you do meet two matching options, the item is probably testing something else as well: meaning, register, or a second fault elsewhere. Read both in the full sentence and choose the one that changes nothing except the mismatch. The general rule is the one that runs through this chapter: fix the one nameable fault, and change nothing else.

The comparison fault hides in sentences that sound entirely natural. 'Meera's marks in English are higher than her brother.' Most people read it without noticing anything wrong. But parallel structure says to compare like with like, and this sentence compares Meera's marks with her brother himself. The fix restores the match: 'higher than her brother's' or 'higher than those of her brother'. In casual speech the short form is common and nobody misunderstands it, which is exactly why it makes a good test item: the fault is real in formal writing, but the ear does not catch it. The Match Test catches it, because step two asks you to name each item - 'marks' and 'brother' - and they are not the same kind of thing.

Item types are described generally; formats, instructions and marking differ between examinations and change over time, and this section does not describe any particular test. The both-standard cases listed are those this chapter never keys wrong; some older or stricter materials may treat them differently. The short comparison ('higher than her brother') is common in speech and keyed only in formal contexts.

  1. Find the joint and name every item's shape before reading the options.
  2. Look for one nameable fault; if you cannot name one, choose 'No error' or 'No improvement'.
  3. Never key a both-standard construction: 'to' once or repeated, or 'a doctor and proud of it'.
  4. Check comparisons compare like with like: 'than that of Delhi', 'than her brother's'.
  5. Keep the verb pattern after 'than' and 'rather': 'would rather walk than take'.
  6. Reject options that fix the pattern but change meaning, register or grammar elsewhere.
  7. In 'Not only' transformations, invert and match both halves.
  8. Do not pick the shortest option by habit; read it in the full sentence.
Exam items test parallel structure through a few recurring types, described here generally: error spotting, sentence improvement, choosing the best version, and transformation. They target faults careful readers agree on: a list that changes form at the last item, a half-repeated 'to', an unbalanced comparison ('cooler than Delhi'), a broken pattern after 'than' or 'rather', a missing inversion after 'Not only', and - under a formal stem - loose correlative placement. Careful items avoid keying both-standard constructions: 'to' stated once or repeated for all, unlike forms with one job, and loose placement in speech. When you cannot name a fault, 'No error' is usually right. When several options match, choose the one that keeps the meaning, fits the register and adds no new error. The Match Test is the whole strategy: find the joint, name the shapes, fix the one mismatch, and change nothing else.

Close reading parallelism

Close reading runs the Match Test along a whole passage: find each joint, name the shapes, see that they match - then ask what the matching, and any break in it, does.

Patterns rarely stand still. Two famous passages show a pattern building and then turning.

PassageHow the pattern buildsWhere it turnsEffect
Dickens, A Tale of Two Cities (1859), opening sentencepair after pair: 'it was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness...''we were all going direct to Heaven, we were all going direct the other way'the expected opposite, 'Hell', is replaced by a dry 'the other way'; many readers hear irony after the grand pairs
Brutus, Julius Caesar'As Caesar loved me, I weep for him; as he was fortunate, I rejoice at it; as he was valiant, I honour him''but, as he was ambitious, I slew him'the frame stays the same while the response turns from honour to killing; the matching form makes the turn feel reasoned
Tagore, 'Where the mind is without fear' (Gitanjali, 1912)clause after clause opens with 'Where', all waiting for a main clausethe poem's one main clause arrives at the end: 'Into that heaven of freedom, my Father, let my country awake'the anaphora describes a hoped-for place; the delayed main clause turns description into prayer
A strong close-reading paragraph has three moves: name the figure, quote the few words that show it, explain the effect. Then add a fourth if you can: say where the pattern changes and why. 'Brutus's speech uses matching as-clauses to present three responses to Caesar's virtues; the fourth keeps the frame but reverses the response, so the killing sounds like the same fair judgement.'

Keep interpretation tied to the words. 'The verbs rise in solemnity' can be defended by what the verbs mean; 'Lincoln was tired' cannot be defended from the text at all.

Picture a passage as a piece of music. Parallel structure is the repeated phrase the listener learns to expect. Close reading listens for three things: the phrase being set up, the phrase climbing a step each time it returns, and the moment the composer changes a note - where the listener sits up. Your answer should say which of the three you are hearing, and quote the bars.

Close reading gathers every tool of the band: the function test and shared elements (S31-S32) to parse the lines, correlatives and focus (S33) to see what is contrasted, the classical figures (S34-S35) to name the patterns, and the drafting precision of S37 to quote exactly. The final section asks you to use all of them on a passage of your own editing - without the scaffolding.

Here is the hard case: deciding whether a break in a pattern is deliberate. In Dickens's opening sentence, the pairs run for many members: best/worst, wisdom/foolishness, belief/incredulity, Light/Darkness, hope/despair, everything/nothing. Then: 'we were all going direct to Heaven, we were all going direct the other way'. The reader has been trained to expect an exact opposite. 'Hell' would complete the pattern. Dickens writes 'the other way'. Is that a slip? Almost certainly not, and the evidence is in the passage. Every earlier pair supplies its opposite exactly; the one place the opposite is withheld is the one where it would be the strongest word. The withheld word draws attention to itself, and the understatement lets a note of irony into a grand, balanced sentence. Contrast a break with no evidence of purpose: a student's list that runs 'reading, writing and to paint'. Nothing in the context makes 'to paint' mean more than the others; it is simply a mismatch. The test for a deliberate break, then, has two parts. Is the pattern strong enough, for long enough, that the reader expects its completion? And does the break land on a word that carries weight? When both are true, name the break and explain its effect; when neither is, call it a fault.

Parallel structure can make a speaker say two opposite things at once. In Julius Caesar, Antony begins: 'Friends, Romans, countrymen, lend me your ears; I come to bury Caesar, not to praise him.' The opening is a tricolon of address - three names for his listeners, widening and warming. The next clause is a neat antithesis: 'to bury Caesar, not to praise him'. On its face, Antony promises not to praise Caesar. Then the speech goes on to praise Caesar, again and again, while repeating that 'Brutus is an honourable man'. The antithesis sets up a promise that the rest of the speech quietly breaks. The balanced form is part of the trick: it sounds so fair and measured that the audience lets him speak - and by the end, the repeated 'honourable' has turned into irony. Parallelism does not only persuade by being clear; it can persuade by sounding reasonable while the meaning slides underneath it.

Passages are quoted from public-domain texts: the Gettysburg Address in a widely reproduced version (early versions differ slightly in wording and punctuation, and dashes are shown here as '-'); Dickens's A Tale of Two Cities (1859); the King James Bible (1611); Shakespeare's Julius Caesar; and Tagore's own English Gitanjali (1912). Readings of effect - rising verbs, irony in 'the other way' - are common interpretations defended from the words, not the only possible ones. Passages attributed to learners were written for this section.

  1. Mark every joint in the passage and the items it joins before you write.
  2. Name the figure, then quote only the words that show it.
  3. Explain the effect on the reader or listener, tied to the words.
  4. Follow the pattern: where it starts, how it builds, where it turns.
  5. Treat a break as deliberate only when the pattern is strong and the break carries weight.
  6. Check where repeated words fall before choosing anaphora, epistrophe or chiasmus.
  7. Quote public-domain texts exactly; paraphrase anything still in copyright.
  8. End a paragraph with the turn, if the passage has one - it is usually the point.
Close reading follows parallel structure through a whole passage. In the Gettysburg Address, paired participles define the nation, a rising tricolon of verbs ('dedicate ... consecrate ... hallow') builds to a limit, 'living and dead' joins the soldiers, 'what we say here' is set against 'what they did here', and 'of the people, by the people, for the people' ends each member on the people. In A Tale of Two Cities, pair after pair builds until 'the other way' withholds the expected opposite. In Julius Caesar, Brutus keeps one frame while his response turns on 'but'; Antony's balanced antithesis makes a promise the speech then breaks. In Tagore's 'Where the mind is without fear', anaphora on 'Where' builds a vision until the one main clause at the end turns it into prayer. The method has three moves and a fourth: name the figure, quote the words, explain the effect, and find where the pattern turns. A break counts as deliberate when the pattern is strong and the break lands on a word that matters.

Independent performance

The Match Test, applied to the whole draft: find each joint, name each item's shape and job, make them match - and keep what is already standard or deliberate.

The decisions fall into four groups. Each group has a different kind of defence.

GroupLinesOne-sentence defence

Keepquiet, well stocked and open late; a scholar and proud of it; we have asked ...; a library, not a luxury'Parallel', 'unlike forms, one job', 'deliberate anaphora with a returning word', 'antithesis'.
The scope line needs one more fact: what Aarav means. If only the computers must be bought this year, reorder: 'computers bought this year and new books'. If both must be, regroup: 'new books and computers, all bought this year'. An editor who cannot ask the writer should flag the line rather than guess.

Notice what the draft does well. Aarav's library is described in three matching items; his closing pair sets a library against a luxury; his 'asked ... waited ... asked again' is a pattern with a purpose. The edit repairs his slips and leaves his craft intact.

Picture yourself at the principal's desk with Aarav's draft and three stamps: FIX, KEEP and ASK. FIX goes on a line only when you can name the one mismatch. KEEP goes on a line when you can name why it is standard or deliberate. ASK goes on the line whose meaning only the writer knows. A line with no stamp is a line you have not yet read closely enough.

This section closes the chapter. Chapter 16 picks up where parallel structure leaves off: the commas and semicolons that punctuate lists, pairs and clauses. Everything here - finding the joint, naming the items - is the first step in punctuating them, and the serial comma question deliberately left out of this chapter is waiting there, along with the semicolons that separate long parallel items.

The hardest decision in the draft is the one that is not about grammar at all. 'We have asked, we have waited, we have asked again.' A strict editor might say the pattern is broken: 'asked, waited, asked again' repeats a verb and adds 'again' to the last member, so the three members are not identical. Another might say the repetition is clumsy and suggest 'we have asked, we have waited, we have pleaded'. But apply the S39 test for a deliberate break. Is the pattern strong? Yes: three members, each 'we have' + a past participle. Does the change land on a word that matters? Yes: 'asked again' tells the principal that the council has already been ignored once. The repetition is the argument. Replacing it with a fresh verb would make the line more varied and less true. So the decision is 'keep', and the defence names the tools: 'Anaphora on we have, with a returning verb that stresses how long the council has waited (S34, S39).' This is what 'defend where the rules bend' means. The rule says match the items; the Master reader knows when a writer has matched them closely enough to be heard, then changed one word so that it will be.

The most important edit in the draft may be the one that changes the fewest words. 'The fund will cover new books and computers bought this year.' If Aarav means only the computers must be new purchases, and the principal reads 'bought this year' as covering the books too, the council may lose half its request: older donated books would fall outside the fund. One reordering - 'computers bought this year and new books' - removes the risk. No grammar rule is broken in the original. Every item is a noun phrase; every item completes 'will cover'. The problem is reach, the question S32 and S37 taught you to ask. That is the surprise of the whole chapter: the most costly parallelism problems are often not mismatches at all, but matches that leave a shared word free to reach too far.

Aarav's draft, and every line in it, was written for this section. The decisions shown are defensible edits for the stated formal reader, not the only acceptable ones: other small fixes can repair the same mismatches, and the scope line depends on an intention the draft does not state. Loose correlative placement is edited here because the reader is formal; it is not an error in speech. List punctuation is left as it stands, since it belongs to Chapter 16.

  1. Read the whole draft once before editing any line.
  2. Name the reader, and let the reader decide register-dependent edits.
  3. Name the joint, the shapes and the jobs in every line.
  4. Fix a line only when you can name its one mismatch, and use the smallest change.
  5. Keep same-job pairings, both-standard forms and deliberate patterns, and say why.
  6. Check every shared word for fit and reach.
  7. Flag a scope you cannot resolve without the writer's intention.
  8. Write each defence in one sentence that names a Master tool.
  9. Reread the finished draft aloud: the writer's voice should still be there.
Independent performance means holding every test at once. In Aarav's draft, the fixes are each one nameable mismatch: 'chatting' among to-phrases; hours compared with a library; 'a signed form' after 'must be'; 'have never ... give up' and 'committed ... for the change', where a shared word fails one item; and a loose correlative that this formal reader would expect to be tight. The scope of 'bought this year' is fixed according to what the writer means - or flagged. The keeps are as important: 'quiet, well stocked and open late' is parallel; 'a scholar and proud of it' pairs unlike forms with one job; 'We have asked, we have waited, we have asked again' is a deliberate anaphora whose returning verb is the argument; 'a library, not a luxury' is an antithesis. Every decision comes with a one-sentence defence naming its tool. That is the Master identity of the chapter: you can analyse parallelism, and you can defend where the rules bend.

Common questions about parallel structure

What is parallel structure?
Parallel structure means giving joined items the same grammatical shape. In I like swimming, cycling and running, all three items are -ing words, so the list reads smoothly. I like swimming, cycling and to run bumps, because the last item changes shape. It applies to lists, pairs joined by and, or and but, comparisons, and bullet points.
What is faulty parallelism?
Faulty parallelism, also called a parallelism error, is when items joined together do not match in shape. She is kind, clever and works hard joins two adjectives and a verb phrase. Fix it by matching: She is kind, clever and hard-working. The fault is in form, not meaning, so the sentence is usually understood, but it reads awkwardly and can confuse.
How do I fix a list that isn't parallel?
Use the Match Test. First, find the joint: and, or, but, either/or, than, or a list. Second, name the shape of each item: noun, -ing phrase, to-phrase, adjective, prepositional phrase or clause. Third, rewrite the odd one to match the rest: reading, writing and to paint becomes reading, writing and painting. Then read each item alone to check it fits.
Do I repeat 'to' in a list?
Either way is correct. State it once for all items: I want to swim, run and cycle. Or repeat it for every item: I want to swim, to run and to cycle. Repeating adds emphasis or clarity in long lists. What careful writers avoid is the half-repeat: to swim, run and to cycle. The same goes for a, the, in and that.
How do I use 'not only... but also' correctly?
Put the same kind of item after each part. She not only sings but also dances: two verbs. The course is not only cheap but also useful: two adjectives. Not only in India but also abroad: two phrases. She not only sings but also the tabla does not match. But also can be shortened to but in many sentences.
Either... or: where does 'either' go?
In formal writing, place either directly before the first of the two matching items: You can either call or write (two verbs). You can call either Asha or Ravi (two names). In speech, looser placement is common and clear: You can either call Asha or Ravi. Tighten it in formal writing. Both... and and neither... nor work the same way.
What is parallelism in comparisons?
Things compared with than or as should match in kind and shape. Swimming is better than running compares two -ing forms. The weather in Delhi is hotter than Shimla compares weather with a city; write than that in Shimla or than Shimla's. To walk is as healthy as running mixes shapes; use Walking is as healthy as running.
Why do bullet points need parallel structure?
Readers scan bullets as one set, so each should start the same way. Plan the trip, Book the tickets, Pack the bags all begin with a command verb. Planning the trip, Book tickets, Your bags breaks the pattern and slows the reader. Check that each bullet also fits the lead-in line: You will learn to... must work with every bullet.
What is parallelism in literature and speeches?
Writers and speakers repeat a structure on purpose to create rhythm, make ideas memorable and press a point. Lincoln's Gettysburg Address ends with government of the people, by the people, for the people. Dickens opens A Tale of Two Cities with It was the best of times, it was the worst of times. Listeners hear the pattern and expect the next beat.
What is a tricolon?
A tricolon is a series of three parallel items, often rising in length or force. Lincoln's of the people, by the people, for the people is a famous example: three prepositional phrases with the same noun. Three feels complete: enough for a pattern, not enough to drag. Julius Caesar's Veni, vidi, vici (I came, I saw, I conquered) is another.
What is anaphora?
Anaphora is repeating the same word or words at the start of successive clauses or sentences. Ecclesiastes 3 in the King James Bible repeats A time to: A time to be born, and a time to die. Speeches use it to build force, as in several famous wartime speeches repeating we shall fight. Repeating the ending instead is called epistrophe.
Is 'He is a doctor and proud of it' wrong?
No. It is standard English. A doctor is a noun phrase and proud of it is an adjective phrase, but both do the same job: they describe him after is. Huddleston and Pullum's Cambridge Grammar of the English Language treats such pairs as normal coordination. The rule to match shapes targets items that differ in both form and job.
What does a list of things look like?
A list of things uses naming words, all the same kind: a bat, a ball and a cap. Each item is a thing you can point to. A bat, a ball and play does not match, because play is a doing word. Fix it by naming a thing: a bat, a ball and a helmet, or by moving play elsewhere.
How do I make a list of actions match?
Use doing words in the same form. We ran, jumped and laughed: three past-tense verbs. We run, jump and laugh: three present-tense verbs. We ran, jumping and laughed mixes forms, so it bumps. Read the list aloud: if one action sounds different from the others, change it to match.
How do I list describing words?
Put describing words (adjectives) together with other describing words: My sister is tall, kind and funny. Each word answers What is she like? My sister is tall, kind and plays football mixes two describing words with an action. Fix it with an adjective (tall, kind and sporty) or give the action its own part: tall and kind, and she plays football.
