Rule 1: The Use of 'Am'

Examples:

  • I am a student.
  • I am going to the market.
  • I am very happy today.

Rule 2: The Use of 'Is'

The word 'is' is used with third-person singular subjects. This includes the pronouns "he," "she," and "it," as well as any singular noun (like 'the dog', 'John', 'the car').

  • He is my best friend.
  • She is a doctor.
  • It is raining outside.
  • The dog is barking loudly.

Rule 3: The Use of 'Are'

The word 'are' is used with plural subjects and the second-person pronoun. This includes "we," "you," and "they," as well as any plural noun (like 'the boys', 'cats', 'people'). Note: 'You' takes 'are' whether it refers to one person or multiple people.

Examples:

  • We are late for school.
  • You are looking beautiful.
  • They are playing football in the park.
  • The birds are flying.

Using Is, Am, Are in Negative Sentences

Questions and Answers

Where do we use 'am'?+

'Am' is used exclusively with the pronoun 'I'.

When should I use 'is'?+

Use 'is' when talking about a single person, place, or thing in the third person (he, she, it, or singular nouns like 'the boy').

Why does 'you' use 'are' even if it's one person?+

In English grammar, 'you' is treated as a plural pronoun in terms of verb conjugation, regardless of whether you are addressing one person or ten. Therefore, it always takes 'are'.

How do you form a question using is, am, are?+

To form a question, move the 'to be' verb to the beginning of the sentence. (e.g., 'He is smart.' becomes 'Is he smart?')
