Last time we looked at possessive adjectives, which MUST have a noun following them:

(possessive adjective) + N:  my, your, his, her, its, our, their

my alarm
your keys
his book
her father
its tail
our children
your hats
their pictures

Now, let’s look at possessive pronouns, which do NOT have a noun following them:

 Pattern:  (possessive pronoun) + (nothing)

Examples:

Where did you get your book?  I bought mine from the local bookstore. (= I bought my book)
I found a pen – is it yours? (= is it your pen)
Mary is done with her project, but Jack didn’t finish his. (= Jack didn’t finish his project)
Mother told me that the sweater on the sofa is hers.  (= the sweater is her sweater)
Did you see the Wilsons got a new tent?  It looks just like ours. (= it looks just like our tent)
John and Susan said that the dog barking last night wasn’t theirs. (= the dog wasn’t their dog)

Note:  The possessive pronouns are used when showing possession with the preposition “of.”

Examples:

A friend of mine gave me that book.  (not friend of me)
That dog of hers is nothing but a troublemaker. (not dog of her)
The Wilsons went out for dinner with some friends of theirs.  (not friends of them)
A neighbor of ours recently got a new car.  (not neighbor of us)

To ask about possession, use “whose”:

Examples:

Whose cell phone is this?  It’s mine.

or (if it’s clear what item is meant)

Whose is this?  It’s mine.

Whose glasses are these?  / Whose are these?  They’re Jack’s.

Exercises.  Complete the following sentences, using one of the possessive pronouns:  mine, ours, yours, his, hers, theirs.

Example:

These are my shoes.  They’re _______. ==> These are my shoes.  They’re mine.

1.    This is my sandwich.  It’s _______.
2.    That is our dog.  It’s _______.

10.    This is your pen.  It’s _______.
