Person, in grammar, is the feature of a language that shows the difference between the speaker, the person spoken to, and a person or thing spoken about. If a word stands for the speaker, it is in the first person. If it stands for the person spoken to, it is in the second person. If it stands for any other person or thing (the person or thing spoken about), it is in the third person. English shows person by a change in the form of a personal pronoun or verb. Nouns are third person.
Different forms of personal pronouns show person. I and we are first person. You is second person. He, she, it, and they are third person.
Regular verbs change form to show person only in the third person, singular, present tense. An -s or -es is added to the first (or second) person, singular, present tense, to form the third person. I drive is first person, you drive is second person, but he drives is third person. The most irregular verb, be, changes form to show person in the singular, present tense as follows: I am, you are, he is. But plural forms of be in the present tense are the same: we are, you are, they are. First and third person forms of be in the singular, past tense are alike: I was is first person; he was is third person. All plural and second person forms use were: we, they, you were.
