Possessive Adjectives

My, your, his, her, its, our, their — adjectives that show ownership before a noun.

What are Possessive Adjectives?

Possessive adjectives are words that show ownership or possession. They tell us who something belongs to. They always come before a noun and function like adjectives, modifying the noun.

They are sometimes called possessive determiners because they introduce a noun phrase and specify which one.

This is my book. (The book belongs to me.)
Where is your car? (The car belongs to you.)
That is their house. (The house belongs to them.)

The Possessive Adjectives

Here is a list of possessive adjectives and the pronouns they correspond to:

Subject Pronoun Possessive Adjective Example
I my This is my phone.
You your Is that your bag?
He his He lost his keys.
She her She loves her cat.
It its The dog wagged its tail.
We our This is our classroom.
They their They sold their old car.

Key Characteristics of Possessive Adjectives

1. Always Precede a Noun

Possessive adjectives must be followed by a noun. They cannot stand alone.

This is my book. (Correct)
This is my. (Incorrect)

2. Do Not Change Form

Possessive adjectives do not change their form based on the number (singular/plural) or gender of the noun they modify.

This is my car.
These are my cars.
This is his sister.
This is his brother.

3. Distinguishing 'Its' from 'It's'

This is a very common point of confusion.

  • Its: This is the possessive adjective for 'it'. It means 'belonging to it'.
    > The dog wagged its tail.
    > The company is known for its innovative products.
  • It's: This is a contraction of 'it is' or 'it has'.
    > It's a beautiful day. (It is a beautiful day.)
    >
    It's been a long time. (It has been a long time.)

4. Distinguishing 'Your' from 'You're'

Another common confusion.

  • Your: This is the possessive adjective for 'you'. It means 'belonging to you'.
    > Is this your pen?
    > What is your name?
  • You're: This is a contraction of 'you are'.
    > You're very kind. (You are very kind.)
    >
    You're going to be late. (You are going to be late.)

5. Distinguishing 'Their', 'There', and 'They're'

These three words sound alike but have different meanings and uses.

  • Their: This is the possessive adjective for 'they'. It means 'belonging to them'.
    > The students submitted their assignments.
    > They live in their own house.
  • There: This indicates a place or is used in 'there is/are'.
    > The book is over there.
    > There are many people here.
  • They're: This is a contraction of 'they are'.
    > They're coming to the party. (They are coming to the party.)

Possessive Adjectives vs. Possessive Pronouns

It's important not to confuse possessive adjectives with possessive pronouns.

Possessive Adjective Possessive Pronoun
my mine
your yours
his his
her hers
its (none)
our ours
their theirs
  • Possessive adjectives always come before a noun: This is my book.
  • Possessive pronouns replace a noun and stand alone: This book is mine.

Common Errors and How to Fix Them

✗ Incorrect ✓ Correct Why
This is mine book. This is my book. 'Mine' is a possessive pronoun, not an adjective.
The cat ate it's food. The cat ate its food. 'Its' is the possessive adjective; 'it's' means 'it is'.
Your going to be late. You're going to be late. 'You're' means 'you are'; 'your' is possessive.
They left there bags. They left their bags. 'Their' is the possessive adjective; 'there' indicates place.

Real-World Examples

"This is my sister, and that's her husband."

"Where did you put your keys? I can't find my phone."
