What part of speech is he or she?

Answer 1

Those pronouns function as adjectives, they are called possessive adjectives.

A possessive adjective is placed before a noun to describe that noun as belonging to someone or something.

The possessive adjectives are: my, your, his, her, its, our, their.

Note: A possessive adjective should not be confused with a possessive pronoun, which is a word that takes the place of a noun that belongs to someone or something.

The possessive pronouns are: mine, yours, his, hers, its, ours, theirs.

He and they are subject pronouns:

He lost the lotto ticket. They were really angry.

You can be a subject or an object pronoun:

You should buy a new ticket. I'll get a new ticket for you.
