What is an object pronoun?

An object pronoun is used as the object of a verb or a preposition, which means that it’s the person or thing affected by some action. It usually appears after the verb or preposition it relates to (e.g., “ask him,” “speak to them”).

The object forms of the personal pronouns are me, us, you, him, her, it, and them. The object form of the interrogative pronoun or relative pronoun used to refer to people is whom.

All other pronouns (e.g., “someone,” “those,” “few”) have only one form that is used for both subject and object.
