If you say my laptop, her brother, or their decision, the possessive word shows how the noun is connected to a person or thing.
English has seven main forms: my, your, his, her, its, our, and their.
They are commonly called possessive adjectives in school grammar. Modern grammar usually calls them possessive determiners because they help identify the noun rather than describe one of its qualities.
What Is a Possessive Adjective?
A possessive adjective is an adjective used before a noun to show possession, relationship, or another close connection.
For example:
I left my passport in the hotel safe.
Naomi introduced her supervisor before the presentation.
The company revised its privacy policy last month.
We changed our itinerary when the weather worsened.
The possessive word comes before the noun it belongs with.
Possessive Adjectives at a Glance
| Personal pronoun | Possessive adjective | Example |
|---|---|---|
| I | my | my appointment |
| you | your | your reservation |
| he | his | his research |
| she | her | her proposal |
| it | its | its purpose |
| we | our | our neighborhood |
| they | their | their equipment |
The form you choose depends on the person or thing connected with the noun.
The Possessive Form Follows the Possessor
The possessive form is chosen according to the possessor or reference point, not according to the noun that follows.
Compare:
Daniel submitted his report.
Daniel submitted his reports.
The noun changes from singular to plural, but his stays the same because Daniel is still the person connected with both.
The same pattern appears here:
Sofia misplaced her key.
Sofia misplaced her keys.
English possessive adjectives do not change to match the number of the noun.
His, Her, and Their
With his and her, look at the person being referred to.
Marcus called his sister after the meeting.
His refers to Marcus, not to the sister.
Elena sold her apartment before moving abroad.
Her refers to Elena, not to the apartment.
Their can refer to more than one person:
The architects presented their revised plans on Monday.
It is also widely used with a singular person when gender is unknown, irrelevant, or when the person uses they.
If someone loses their access card, they should contact reception.
The noun after the possessive does not determine which form you choose.
Possession Does Not Always Mean Ownership
The word possessive can suggest ownership, but these forms express a much wider range of relationships.
Family and Personal Relationships
Leah invited her cousin to the exhibition.
The cousin does not “belong” to Leah. The possessive shows a relationship.
Body Parts
Adrian injured his shoulder during training.
English commonly uses possessive forms with body parts when the person is clear.
Work and Roles
The director thanked her assistant for handling the schedule.
This also expresses a relationship rather than literal ownership.
Ideas, Features, and Characteristics
The report lost its original focus after several revisions.
The town is known for its historic market.
Possessive adjectives can therefore show belonging, relationships, association, parts, roles, and other close connections.
Possessive Adjective vs Possessive Pronoun
Possessive adjectives and possessive pronouns express similar relationships, but they behave differently.
A possessive adjective comes before a noun:
That is my folder.
A possessive pronoun stands in place of the noun phrase:
That folder is mine.
Here are the main forms:
| Possessive adjective | Possessive pronoun |
|---|---|
| my | mine |
| your | yours |
| his | his |
| her | hers |
| its | rarely used independently |
| our | ours |
| their | theirs |
Compare:
This is our table.
This table is ours.
And:
I found her umbrella near the entrance.
The umbrella near the entrance is hers.
Independent possessive pronouns do not normally come directly before nouns.
Incorrect: mine laptop
Correct: my laptop
Incorrect: theirs apartment
Correct: their apartment
Why His Looks the Same in Both Patterns
Most possessive adjective and pronoun forms are different:
my → mine
her → hers
our → ours
But his has the same form in both uses.
Before a noun:
Daniel collected his luggage.
Standing independently:
The black suitcase is his.
Its position and function tell you how his is being used.
What About Its as a Possessive Pronoun?
Its works normally before a noun:
The museum changed its opening hours.
English generally avoids using its by itself as an ordinary possessive pronoun in the way we use mine, yours, hers, ours, or theirs.
For example:
Unnatural: The final decision was its.
However, its can appear in expressions with own:
The project developed an identity of its own.
So independent its is best understood as highly restricted rather than completely absent.
Its vs It’s
Its and it’s have different jobs.
Its is possessive:
The device stores its data locally.
It’s is a contraction of it is or it has:
It’s already connected to the network.
It’s been difficult to reproduce the error.
A useful check is to expand the contraction.
If it is or it has works, use it’s.
If the word shows possession or connection before a noun, use its.
Possessive Adjectives Do Not Take Apostrophes
Possessive adjective forms themselves do not take apostrophes.
Compare:
your schedule
you’re early
and:
their office
they’re relocating
The apostrophe forms are contractions, not possessive adjectives.
Possessive Adjective vs Possessive Noun
English can express a similar relationship with a possessive adjective or a possessive noun.
Compare:
Amelia’s presentation starts at ten.
and:
Her presentation starts at ten.
Amelia’s is a possessive noun form. Her is a possessive adjective, or in modern terminology, a possessive determiner.
Possessive Adjectives and Articles
Possessive adjectives normally occupy the same central determiner position as a, an, and the.
That is why English says:
my jacket
not:
Incorrect: the my jacket
And:
their apartment
not:
Incorrect: a their apartment
English normally uses one central determiner in this position.
Other words can still appear in the noun phrase:
my two closest colleagues
their three remaining options
our new regional office
The possessive comes before numbers and ordinary descriptive adjectives.
Why Modern Grammar Calls Them Possessive Determiners
Words such as my, your, his, her, its, our, and their do not behave like ordinary descriptive adjectives.
Compare:
my old bicycle
Here, old describes a quality of the bicycle.
My does something different. It identifies the bicycle through its relationship to the speaker.
Possessives also occupy the determiner position in a noun phrase:
their detailed proposal
our three remaining candidates
That is why modern grammar generally calls these words possessive determiners.
The term possessive adjective remains widely used in school grammar and English-learning materials, so both terms are useful to recognize.
A less common form is one’s, used especially in formal or general statements:
One should protect one’s privacy online.
English possessive forms become easier to use when you focus on the person or thing the noun is connected to. Choose the form from that relationship, then keep it unchanged whether the noun that follows is singular or plural.
