Possessive Pronouns

What are Possessive Pronouns?

Possessive pronouns are words that show ownership or possession. They replace possessive nouns (e.g., John's car) or possessive adjectives + nouns (e.g., my car) to avoid repetition.

There are two types of possessive forms:

Possessive Adjectives (also called possessive determiners): These come before a noun (e.g., my book, your car).
Possessive Pronouns: These stand alone and replace the noun phrase (e.g., The book is mine.).

This topic focuses on Possessive Pronouns.

Subject Pronoun	Possessive Adjective	Possessive Pronoun	Example (Possessive Pronoun)
I	my	mine	That book is mine.
You	your	yours	Is this pen yours?
He	his	his	The blue car is his.
She	her	hers	That idea was hers.
It	its	(none)	(Not typically used as a possessive pronoun)
We	our	ours	The house is ours.
They	their	theirs	Those seats are theirs.

1. When to Use Possessive Pronouns

We use possessive pronouns to:

a. Avoid Repetition

They replace a noun that has already been mentioned, making sentences more concise.

This is my car. That is your car. (Repetitive)
This is my car. That is yours. (More concise)

Is this John's book? No, it's not his.

b. Show Ownership

They clearly indicate who something belongs to.

The decision was hers. (The decision belonged to her.)
These keys are mine. (These keys belong to me.)

2. Important Points to Remember

a. No Apostrophes

Possessive pronouns never use apostrophes.

✗ The cat is her's.
✓ The cat is hers.

✗ Is this your's?
✓ Is this yours?

b. 'Its' vs. 'It's'

This is a common point of confusion.
* Its is a possessive adjective (e.g., The dog wagged its tail.). There is no possessive pronoun form for 'it'.
* It's is a contraction of 'it is' or 'it has' (e.g., It's a beautiful day.).

c. Possessive Pronouns Stand Alone

Unlike possessive adjectives, possessive pronouns do not come before a noun. They function as the noun itself.

Possessive Adjective: This is my phone.
Possessive Pronoun: This phone is mine.

Common Errors and How to Fix Them

✗ Incorrect	✓ Correct	Why
That's her's.	That's hers.	Possessive pronouns do not use apostrophes.
Is this your's book?	Is this your book? (Possessive Adjective) Is this book yours? (Possessive Pronoun)	'Yours' is a pronoun and stands alone. 'Your' is an adjective and modifies 'book'.
The dog wagged it's tail.	The dog wagged its tail.	'Its' shows possession; 'it's' means 'it is' or 'it has'.
Our's is the biggest house.	Ours is the biggest house.	Possessive pronouns do not use apostrophes.
