Possessive Adjectives: Forms, Rules and Examples in English

Overview

A possessive adjective is a word that modifies a noun to show that it belongs to or is associated with a particular person or thing. The eight possessive adjectives in English are my, your, his, her, its, our, your, and their. Each one corresponds to a subject pronoun and indicates who the owner or associator is.

Two rules matter most at this level: possessive adjectives agree with the owner, not with the noun they modify, and they are different in form and function from possessive pronouns.

The Eight Possessive Adjectives

Each possessive adjective corresponds to a subject pronoun.

The form your serves both singular and plural subjects, so context determines whether one person or several are being addressed.

Agreement With the Owner, Not the Noun

Possessive adjectives agree with the owner, not with the noun that follows them. The noun being owned has no effect on the form of the adjective. The only factor is the identity of the owner.

This rule holds even when the noun being modified is plural. The possessive adjective does not become plural to match the noun.

Possessive Adjectives in Sentences

Possessive adjectives always appear directly before the noun they modify. They do not stand alone. A possessive adjective always precedes a noun; a possessive pronoun replaces one.

A possessive adjective can precede nouns of any type: singular or plural, countable or uncountable, concrete or abstract.

Because they sit before the noun, possessive adjectives occupy the same position as articles and other determiners. They cannot be used together with an article in the same noun phrase.

Its Versus It's

The possessive adjective its is frequently confused with the contraction it's, which means it is or it has. These two forms are different in meaning and grammatical function.

Its without an apostrophe is the possessive adjective. It modifies a noun to show that the noun belongs to or is associated with the thing already mentioned.

It's with an apostrophe is a contraction of it is or it has.

To check which form is correct, try expanding the word to it is or it has. If the sentence still makes sense, the apostrophe form is correct. If it does not, its is needed.

Comparing Possessive Adjectives and Possessive Pronouns

Note that his is the only form identical as both a possessive adjective and a possessive pronoun. Context makes the function clear: his jacket uses it as an adjective, while the jacket is his uses it as a pronoun.

Common Mistakes to Avoid

Mistake 1: Choosing the Possessive Adjective Based on the Noun Rather Than the Owner

In English, the noun being owned has no bearing on the form of the possessive adjective. Only the identity of the owner matters.

Mistake 2: Confusing Its and It's

Using it's where its is required, or the reverse, is a common error in both learner and native speaker writing. The apostrophe marks a contraction, not possession.

Mistake 3: Using a Possessive Adjective Together With an Article

A possessive adjective functions as a determiner and takes the place of an article. Placing both in the same noun phrase is ungrammatical.

Mistake 4: Using Their Instead of There or They're

Their is a possessive adjective indicating ownership. There is an adverb of place or an existential subject. They're is a contraction of they are. These three words sound identical and are frequently confused in writing.

Mistake 5: Using Your Instead of You're

Your is a possessive adjective. You're is a contraction of you are.

Mistake 6: Omitting the Possessive Adjective Where English Requires It

Some languages use a definite article where English uses a possessive adjective, particularly with body parts, clothing, and personal belongings.
