What is it?

The verb 'to be' (am, is, are, was, were, been, being) acts as an auxiliary verb when it helps another main verb form different tenses, especially continuous tenses. It doesn't show the main action itself but helps the main verb express when something is happening. Think of it as a helper verb.

Simple Example

Quick Example

Imagine your friend is playing cricket. We can say, 'He is playing cricket now.' Here, 'is' is the auxiliary verb helping 'playing' to show that the action is happening right now.

Worked Example

Step-by-Step

Let's see how 'to be' helps:---Step 1: Identify the main action. In the sentence 'I am eating my lunch,' the main action is 'eating.'---Step 2: Identify the helper verb. 'Am' is helping 'eating' to show that the action is happening at this moment.---Step 3: Recognize 'am' as a form of 'to be.'---Step 4: Therefore, 'am' is acting as an auxiliary verb, making the sentence 'I am eating my lunch' a present continuous tense.---Answer: 'Am' is the auxiliary verb.

Common Mistakes

MISTAKE: Using 'to be' as a main verb when it should be an auxiliary verb with another action verb. For example, 'She is happy dancing.' | CORRECTION: 'She is dancing happily.' Here, 'is' helps 'dancing.' 'Happy' describes how she dances.

MISTAKE: Incorrectly matching the form of 'to be' with the subject. For example, 'They is going to the market.' | CORRECTION: 'They are going to the market.' 'Are' matches with 'they.'

MISTAKE: Forgetting to use 'to be' when forming continuous tenses. For example, 'I watching TV.' | CORRECTION: 'I am watching TV.' 'Am' is needed to form the present continuous tense.
