Possessive adjectives vs possessive pronouns

Possessive Adjectives vs Possessive Pronouns

Both possessive adjectives and possessive pronouns show that something belongs to someone. The key difference is simple: possessive adjectives come BEFORE a noun, while possessive pronouns stand ALONE without a noun. For example, "my book" uses the adjective my, but "this book is mine" uses the pronoun mine. Understanding this difference will help you speak and write correctly.

Side-by-Side Comparison

Possessive adjectives (my, your, his, her, its, our, their) always come before a noun to describe who owns something. Possessive pronouns (mine, yours, his, hers, its, ours, theirs) replace the noun entirely and stand alone. Notice that some forms look the same (his, its) but function differently depending on how you use them.

Quick Memory Trick

Try this: possessive adjectives are like a label on something (my pen, your bag). Possessive pronouns are like the owner speaking about their own item (this is mine, that is yours). If you can put a noun after the possessive word, use the adjective form. If nothing follows it, use the pronoun form.

Possessive Adjectives vs Possessive Pronouns: Full Comparison

Person	Possessive Adjective	Example (Adjective)	Possessive Pronoun	Example (Pronoun)
1st Person Singular	my	This is my book.	mine	This book is mine.
2nd Person Singular / Plural	your	Is that your coat?	yours	Is that coat yours?
3rd Person Singular (Male)	his	I borrowed his pen.	his	That pen is his.
3rd Person Singular (Female)	her	She left her bag here.	hers	That bag is hers.
3rd Person Singular (Neutral)	its	The dog wagged its tail.	—	No standard possessive pronoun form. English does not use a possessive pronoun equivalent for inanimate objects.
1st Person Plural	our	We cleaned our room.	ours	That room is ours.
3rd Person Plural	their	They parked their car outside.	theirs	That car is theirs.

Key Difference: A possessive adjective always comes directly before a noun and modifies it (e.g. my book, their car). A possessive pronoun stands alone and replaces the noun + possessive adjective combination entirely (e.g. "This book is mine" replaces "This book is my book"; "The car is theirs" replaces "The car is their car"). Note that his and its are identical in both forms, whereas all other pronouns take a distinct ending.

When to use it

Describing What You Own

Use possessive adjectives when you describe something that belongs to you or someone else with a noun.

"This is my house and that is your garden."

Comparing Belongings

Use possessive pronouns when comparing two people's items or saying something belongs to someone.

"My pen is blue, but yours is black."

Answering 'Whose' Questions

Use possessive pronouns to answer questions about ownership without repeating the noun.

"Whose bag is this?" "It's mine."

Common Mistakes

Wrong

This is my.

✓

Correct

This is mine.

Use the pronoun 'mine' when the noun is not stated. 'My' always needs a noun.

Wrong

Your car and my are parked outside.

✓

Correct

Your car and mine are parked outside.

Use 'mine' to replace 'my car'. The pronoun stands alone without repeating the noun.

Wrong

This is her pen, this is him.

✓

Correct

This is her pen, this is his.

Use 'his' (possessive pronoun), not 'him' (object pronoun). They sound similar but have different meanings.

Possessive pronouns (mine, yours, his, hers, its, ours, theirs) stand alone without a noun after them.
Never use a possessive adjective when the noun is missing; use a pronoun instead.

Both show ownership, but their position in the sentence determines whether you use adjective or pronoun.
