Possessive pronoun
mine
yours
his
hers
-
ours
theirs

 

Be careful!
Possessive pronouns do not have an apostrophe: Is that car yours/hers/ours/theirs? (NOT Is that car your's/her's/our's/their's?)

We can use a possessive pronoun instead of a full noun phrase to avoid repeating words:

Is that John's car?
     No, it's mine. (NOT No, it's [my car].)

Whose coat is this?
     Is it yours? (NOT Is it [your coat]?)

Her coat is grey.
     Mine is brown. (NOT [My coat] is brown.)

Level: intermediate

We can use possessive pronouns and nouns after of. We can say:

Susan is one of my friends. > Susan is a friend of mine.
(NOT Susan is a friend of me.)

I am one of Susan's friends. > I am a friend of Susan's.
(NOT I am a friend of Susan.)
