Possessive Adjectives
Possessive adjectives are not pronouns, but they are important to learn before studying Possessive Pronouns below. Possessive Adjectives are used before nouns to identify the owner of something:
- my + noun
- your + noun
- his + noun
- her + noun
- its + noun
- our + noun
- their + noun
What is your name?
Jeff gave me his phone number.
I can't drive my car because its tire is flat.
Our shop isn't very big.
Of & 's
Possessive adjectives are similar to using 's with nouns to show possession:
- Jeff's phone number = his phone number
- My car's frame = its frame
- Jennifer's vehicle = her vehicle
- Steve and Pat's teacher = their teacher
We can also show possession with of:
- The door of the garage is open.
- The garage's door is open.
- The flag of Canada is red and white.
- Canada's flag is red and white.
- The price of the tire is $50.
- The tire's price is $50.
Using of to show possession is not common when talking about people:
The brother of Jennifer is nice.- Jennifer's brother is nice.
The house of Phil and Margaret is big.- Phil and Margaret's house is big.
The cat of Samantha is cute.- Samantha's cat is cute.
Possessive Pronouns
Possessive pronouns have the same meaning as a possessive adjective + noun:
- my + noun = mine
- your + noun = yours
- his + noun = his
- her + noun = hers
- our + noun = ours
- their + noun = theirs
- This is not your phone. It is mine. (my phone)
- I don't have a pencil. May I borrow yours? (your pencil)
- Jenny ate my dinner, and I ate hers. (her dinner)
Be careful! "His" is a possessive adjective, but it is also a possessive pronoun. This means "his" can be used with or without a noun:
Where's Paul? This is his jacket.
or
Where's Paul? This is his.
Notice the differences between subject pronouns, object pronouns, and possessive adjectives:
| Subject Pronouns | Object Pronouns | Possessive Adjectives | Possessive Pronouns |
| I | me | my | mine |
| you | you | your | yours |
| he | him | his | his |
| she | her | her | hers |
| it | it | its | - |
| we | us | our | ours |
| they | them | their | theirs |
Whose...?
Whose is used to ask about possession. It can be used with or without nouns:
Whose / Whose car is that?
(Is it your car? Is it Jeff's car? Is it Michelle's car?)
- It's Jeff's.
Whose / Whose money is this?
Is it my money (mine)? Is it your money (yours)?
