What is the difference between a main verb and a helping verb?

In one line

The rule

Main verbs tell what the subject does or is. Helping verbs (auxiliary verbs) are used with main verbs to form tenses, moods, or voices.

Let's understand it simply

Imagine you are playing cricket. The main verb is like the batter — the one doing the main action (hitting the ball). The helping verb is like the runner who helps the batter score runs. The batter (main verb) cannot always play alone; sometimes, the runner (helping verb) is needed to complete the game (sentence).

For example, in “She is running,” “running” is the main verb (the action), and “is” is the helping verb (it helps show when the action is happening).

How it works

1. Every sentence needs a verb to show action or state.
2. The main verb tells what is happening (eat, play, run, sleep).
3. Sometimes, the main verb needs help to show time (tense), possibility, or if the action is finished.
4. Helping verbs like is, am, are, was, were, has, have, had, will, can, may, must, do, does, did — are added before the main verb.
5. Together, they make the meaning clear ("She has eaten" — 'has' helps 'eaten').

The story behind it

The idea of helping verbs comes from the need to show time, mood, or voice in English. As English grew, people started using extra words to make sentences clearer. These extra words became known as helping verbs or auxiliary verbs. They help the main verb do its job better.

Where you see it in real life

• In the kitchen: “Mummy is cooking.” — 'is' (helping), 'cooking' (main).
• Cricket match: “Virat has scored a century.” — 'has' (helping), 'scored' (main).
• School: “We are studying English.” — 'are' (helping), 'studying' (main).
• TV news: “The Prime Minister will visit tomorrow.” — 'will' (helping), 'visit' (main).
• Morning routine: “I have brushed my teeth.” — 'have' (helping), 'brushed' (main).

Why it matters

• Helps you make correct sentences in English.
• Lets you talk about the past, present, and future easily.
• Needed for questions and negatives ("Do you like tea?" — 'do' is helping).
• Important for exams and writing stories, letters, or essays.

Common mistakes

• Mixing up the two: Thinking 'is' or 'have' is the main verb (but they only help).
• Forgetting the helping verb when needed: Saying “She going to school” instead of “She is going to school.”
• Using two main verbs together: “He eat plays cricket” (wrong). Only one main verb, others must be helping.

Remember it

Main verb = main action. Helping verb = helper. If there are two verbs together, the first is usually helping, the second is main.
