Possessive Pronouns - ENGLISH CLUB

Possessive Pronouns

We use possessive pronouns to refer to a specific person/people or thing/things (the "antecedent") belonging to a person/people (and sometimes belonging to an animal/animals or thing/things).
We use possessive pronouns depending on:

• number: singular (eg: mine) or plural (eg: ours)
• person: 1st person (eg: mine), 2nd person (eg: yours) or 3rd person (eg: his)
• gender: male (his), female (hers)

Below are the possessive pronouns, followed by some example sentences. Notice that each possessive pronoun can:

• be subject or object
• refer to a singular or plural antecedent
