Possessive adjectives (my, your, his) go before a noun, while possessive pronouns (mine, yours, his) stand alone. This lesson explains the difference so you can show ownership without repeating the noun.
English has two ways to show possession with pronouns, and the difference is purely structural. A possessive adjective must be followed by a noun — my car, your keys, their house. A possessive pronoun stands completely alone and replaces the noun — mine, yours, theirs. Both express the same ownership; only the grammar differs.
The practical value of possessive pronouns is that they let you avoid repetition. Instead of This is my car and that is your car, you say This is my car and that is yours. In conversation this is not optional polish — repeating the noun sounds distinctly unnatural to a native ear.
The forms are close enough to cause confusion but regular enough to learn quickly. Most possessive pronouns simply add -s to the adjective: your becomes yours, her becomes hers, our becomes ours, their becomes theirs. The exceptions are my, which becomes the irregular mine, and his, which does not change at all. Its has no possessive pronoun form in normal use.
How to form Possessive Adjectives and Pronouns
| Subject | Possessive adjective | Possessive pronoun | Example |
|---|---|---|---|
| I | my | mine | My bag is here. That one is mine. |
| you | your | yours | Your seat is by the window. Is this yours? |
| he | his | his | His coat is black. The blue one isn't his. |
| she | her | hers | Her office is upstairs. This desk is hers. |
| it | its | — | The dog ate its food. |
| we | our | ours | Our car is outside. The red one is ours. |
| they | their | theirs | Their tickets arrived. Ours came before theirs. |
Possessive Adjectives and Pronouns: the key rules
-
Possessive adjectives (my, your, his, her, our, their) need a noun; possessive pronouns (mine, yours, his, hers, ours, theirs) replace it.
This is my seat. This seat is mine.
-
Use the pronoun to avoid repeating the noun.
My phone is older than yours.
-
Whose asks about ownership, and both forms can answer it.
Whose bag is this? — It's her bag. / It's hers.
-
'A friend of mine' uses the pronoun in a common fixed pattern.
I met a friend of mine at the station.
When to use Possessive Adjectives and Pronouns
-
Avoiding repetition of a noun
The main reason possessive pronouns exist — saying whose without naming the thing again.
My phone is broken, so I'm using hers.
-
Comparing possessions
Contrasting two owners in a single sentence, which is where both forms often appear together.
Your flat is bigger than ours.
-
Answering whose questions
A possessive pronoun makes a complete answer on its own.
Whose jacket is this? — It's mine.
-
The of mine structure
A fixed pattern combining an article or determiner with a possessive pronoun.
He's a friend of mine. That neighbour of theirs is very loud.
my vs. mine
One simple test settles every case: look at what comes next in the sentence.
Possessive adjective — noun follows
my, your, his, her, its, our, their. Cannot stand alone and never takes an article.
My house is small. Their children are grown up.
Possessive pronoun — nothing follows
mine, yours, his, hers, ours, theirs. Replaces the whole noun phrase.
The small house is mine. Those children are theirs.

Possessive Adjectives and Pronouns: frequently asked questions
Why does his stay the same in both forms?
Historical accident rather than logic. Most possessive pronouns were formed by adding -s to the adjective, but his already ended in -s from Old English, so no further ending was added. This makes his the only form that works identically as both adjective and pronoun: His car is new and That car is his are both correct. You simply have to read the sentence to know which role it is playing.
Is there a possessive pronoun for it?
Not in normal use. The form its would be the logical pronoun, but English speakers avoid it — nobody says That collar is its. When ownership by a thing needs stating, speakers rephrase: That collar belongs to the dog, or It's the dog's. This gap is not a problem in practice, because inanimate possession rarely needs a standalone pronoun.
Do possessive pronouns take an apostrophe?
Never. Yours, hers, ours, theirs and its are all written without an apostrophe, exactly like his. Writing your's or her's is always an error. The only apostrophe form to be careful of is it's, which is not a possessive at all but a contraction of it is or it has. The rule to remember is that possessive pronouns never take apostrophes.
What does a friend of mine mean, and why not a my friend?
English does not allow an article and a possessive adjective before the same noun, so a my friend is impossible. To combine the two meanings — one of several, and belonging to me — English uses the of structure with a possessive pronoun: a friend of mine. The same applies to that book of yours and some neighbours of theirs, where the structure adds a subtle sense of one among several.
