1. Definition and Role of “Is, Am, Are” in English Grammar
The verbs is, am, and are are the present tense forms of the verb to be. They function primarily as linking verbs, connecting the subject of a sentence with a subject complement that describes or identifies it. This linking role makes them essential for constructing sentences about identity, characteristics, locations, and states of being.
Classified as auxiliary or copula verbs, is, am, and are are used to form predicate structures, express existence, or describe ongoing conditions. Their correct use depends on the grammatical person and number of the subject:
- Is: used with third-person singular subjects (he, she, it, singular nouns)
- Am: used exclusively with the first-person singular (I)
- Are: used with second-person singular and plural subjects, as well as third-person plural subjects (you, they, plural nouns)
Understanding the contexts in which these forms are used is critical for constructing grammatically correct sentences. They appear in numerous sentence types, including declarative, interrogative, negative, and conditional sentences.
2. Structural Breakdown of “Is, Am, Are” Sentences
Basic Sentence Structure
The fundamental structure for “is, am, are” sentences involves a subject followed by the correct form of the verb to be. The basic formula is:
| Subject | Verb (is, am, are) | Complement/Predicate |
|---|---|---|
| He | is | a teacher |
| I | am | a student |

Sentence Types
These basic structures can be expanded to form different sentence types:
- Declarative: She is a doctor.
- Interrogative: Are you ready?

| I | am not | I am not tired. |
| He | is not / isn’t | He is not hungry. |
| They | are not / aren’t | They are not coming. |
Interrogative Forms
Questions are formed by inverting the verb and subject or using question words:
| Question Type | Structure | Examples |
