You use to be to talk about who someone is, how old they are, how they feel, where they are, or to describe things. For example, I am happy, She is a student, or They are in London. Each form matches a specific subject pronoun. Am is for I. Is is for he, she, it, and singular nouns. Are is for you, we, they, and plural nouns.
