Question 1

What is a preposition?

Accepted Answer

A preposition is a word that links a noun phrase to the rest of the sentence and names the relation: place (under the bed), time (since Monday), direction (into the box), tool (with a spoon) or topic. Place is its core meaning, not its only one. Test it: remove the noun phrase after it; if the sentence breaks, it is a preposition.

Question 2

When do I use in, on and at for time?

Accepted Answer

Use in for longer stretches (in June, in 2015, in the morning), on for single days and dates (on Monday, on 4 July, on Monday morning), and at for clock times and points (at six, at noon, at night). Next, last, this and every take none: next week. At the weekend is British; on the weekend is American. Both are standard.

Question 3

When do I use in, on and at for place?

Accepted Answer

Use in for a container or area (in the kitchen, in Delhi), on for a surface (on the table) and at for a point where you meet, stop or do an activity (at the gate, at school). It is on the bus and on the train but in the car. In hospital (British) and in the hospital (American) are both standard.

Question 4

What is the difference between since and for?

Accepted Answer

Since takes a starting point; for takes a length of time. I have lived here since 2020; I have lived here for five years. 'Since two years' is a common Indian English pattern, but the standard written form is for two years. Both usually go with the present perfect: I have been here since Monday, not I am here since Monday.

Question 5

Can you end a sentence with a preposition?

Accepted Answer

Yes. Ending a sentence with a preposition is normal, standard English: What are you looking at? The ban came from seventeenth- and eighteenth-century critics, and the major grammars of English treat stranding as fully standard. The formal alternative, With whom did you go?, is also correct. Only the doubled version, the house in which I live in, is wrong.

Question 6

What is the difference between between and among?

Accepted Answer

Use between for separate items you can name, linked one by one, whatever the number: between her two cousins, a treaty between three countries. Use among for a group seen as one mass: among the crowd, among friends. The rule that between is only for two is a myth; between three is standard. The fixed phrase is between you and me.

Question 7

What is the difference between in and into?

Accepted Answer

In usually tells where something is; into tells movement from outside to inside: the cat is in the box; the cat jumped into the box. After verbs like put, jump, fall and throw, in is also normal: jump in the pool, put it in the bag. Into makes the journey clearer. For something just sitting there, use in, never into.

Question 8

What is the difference between by and until?

Accepted Answer

By sets a deadline: no later than that point. Until means something continues right up to that point and then stops. Hand in the form by Friday. The library is open until six. Hand in the form until Friday sounds as if you keep handing it in all week. Not until means not before: I won't know until Friday.

Question 9

Is "discuss about" correct?

Accepted Answer

The standard form is discuss without about: we discussed the plan. Discuss about is a common pattern, especially in Indian English, borrowed from talk about and a discussion about, but exams expect discuss the plan. The noun keeps its partner: a discussion about the plan. Enter, reach, marry and lack work the same way: enter the room, reach Chennai.

Question 10

What are dependent prepositions, like good at and interested in?

Accepted Answer

They are fixed pairs to learn as chunks, not rules you can work out: good at, afraid of, proud of, interested in, keen on, responsible for, worried about, kind to, married to. Verbs and nouns have them too: depend on, listen to, a reason for. Learn the word and its partner together, and check a learner's dictionary.

Question 11

Are before and after prepositions or conjunctions?

Accepted Answer

Both, in traditional grammar: what follows decides. Before, after, since and until are prepositions before a noun phrase or -ing form (after lunch, after eating) and conjunctions before a clause with its own subject and verb (after we ate). The same test explains despite and although: despite the rain, although it rained. Despite it rained is wrong.

Question 12

What is the difference between a phrasal verb and a preposition?

Accepted Answer

In a phrasal verb the small word is a particle that belongs to the verb and can move: look up the word, look the word up. A preposition is glued to its noun phrase: run up the hill, never run the hill up. With a pronoun, a particle goes after it (turn it off); a preposition stays in front (look after him).

Question 13

Do prepositions only show place?

Accepted Answer

No. Place is where most prepositions began, but they name many relations: time (on Monday), direction (into the room), company (with a friend), tool (with a spoon), cause (because of the rain), topic (a book about birds) and possession (the roof of the house). A preposition is defined by its job, linking a noun phrase to the sentence, not by meaning position.

Question 14

Is it by bus or by the bus?

Accepted Answer

By bus. When by tells how you travel, English uses the bare noun with no the or a: by bus, by train, by car, by boat. If you want the, switch preposition: on the bus, in the car. Walking is on foot in careful English, though by foot is sometimes heard.

Question 15

What is a prepositional phrase?

Accepted Answer

A prepositional phrase is a preposition plus its partner, the noun phrase after it: under the bed, after lunch, with my sister. The phrase runs from the preposition to the end of the partner, so under the big old bed is one phrase of five words. It can answer a question on its own and can often move: After lunch, we play.
