What Are Possessive Pronouns and Adjectives?

Possessive pronouns and adjectives show ownership or belonging. They help us understand who something belongs to.

Possessive Adjectives

Possessive adjectives come before a noun. They tell us who owns something.

Examples:

• This is my book.
• That is your hat.
• She loves her cat.
• He forgot his keys.
• We are going to our school.
• They have their bags.

List of Possessive Adjectives:

• My
• Your
• His
• Her
• Its
• Our
• Their

Possessive Pronouns

Possessive pronouns replace a noun. They stand alone and do not need another noun after them.

Examples:

• This book is mine.
• That hat is yours.
• The cat is hers.
• The keys are his.
• The school is ours.
• The bags are theirs.

List of Possessive Pronouns:

• Mine
• Yours
• His
• Hers
• Its (rarely used)
• Ours
• Theirs

Difference Between Possessive Adjectives and Pronouns

It is easy to mix them up! Look at these sentences:

• This is my book. (my is a possessive adjective)
• This book is mine. (mine is a possessive pronoun)

Both sentences talk about the same thing, but the words are different. Possessive adjectives come before nouns, while possessive pronouns replace nouns.

More Examples:

Possessive Adjective	Possessive Pronoun
This is my pen.	This pen is mine.
That is your bag.	That bag is yours.
This is her dress.	This dress is hers.
He forgot his wallet.	This wallet is his.
We love our house.	This house is ours.
They brought their car.	That car is theirs.

How to Use Possessive Pronouns and Adjectives Correctly

Here are some easy rules to follow:

1. Possessive adjectives always come before a noun. (Example: my bag, your dog, their house)
2. Possessive pronouns never have a noun after them. They replace a noun. (Example: This is mine, That is yours, The book is ours)
3. Do not use an apostrophe (‘) in possessive pronouns or adjectives. People often confuse its and it’s.
   • Its shows ownership. (The dog wagged its tail.)
   • It’s is short for it is. (It’s raining today.)
