Possessive adjectives are words that identify the person, animal, group, or thing associated with a noun. English has seven core forms, my, your, his, her, its, our, and their; each appears before a noun or noun phrase, as in my phone or their new house.
Key Facts at a Glance
- A possessive adjective modifies a noun and normally appears directly before that noun.
- The seven core forms are my, your, his, her, its, our, and their.
- The form agrees with the possessor, not with the possessed object.
- Possessive adjectives do not take an article before them: write my car, not the my car.
- Possessive pronouns such as mine and theirs replace a noun phrase and cannot normally modify a following noun.
- An apostrophe does not mark possession in its, yours, or theirs.
What Are Possessive Adjectives?
Possessive adjectives identify a relationship between a possessor and a noun. The relationship may involve ownership, family connection, authorship, membership, origin, or physical association, so my sister, our team, and the company’s policy are all possessive relationships even though they do not describe the same kind of ownership.
Traditional school grammar calls my, your, and similar words possessive adjectives because they describe nouns. Modern reference grammars more often classify them as possessive determiners, because they occupy the determiner position that can otherwise contain a, the, this, or each. The label differs, but the practical rule remains stable: my needs a noun, as in my answer.
A useful distinction is between the possessor and the possessed noun. In The children lost their backpacks, the children are the possessors, while backpacks is the possessed noun. The form their reflects the children, not the number of backpacks.
Are Possessive Adjectives Really Adjectives?
In traditional grammar, possessive adjectives are adjectives because they describe a noun. In modern syntax, my, your, his, her, its, our, and their are determiners because they occupy the first position in a noun phrase and usually cannot be intensified or compared like ordinary adjectives.
The distinction matters when diagnosing errors. An ordinary adjective can follow an article, as in the red car. A possessive determiner cannot normally combine with an article: my red car is correct, but the my red car is not.
Which Possessive Adjective Should You Use?
Choose a possessive adjective according to the grammatical person and number of the possessor. Third-person singular forms also reflect the possessor’s established gender or, for nonhuman entities, the conventional use of its.
| Possessor | Person and number | Possessive adjective | Example |
|---|---|---|---|
| I | First-person singular | my | I submitted my report. |
| You | Second-person singular | your | You forgot your keys. |
| He | Third-person singular masculine | his | Marcus washed his car. |
| She | Third-person singular feminine | her | Elena called her brother. |
| It | Third-person singular nonhuman | its | The bird opened its wings. |
| We | First-person plural | our | We finished our project. |
| You | Second-person plural | your | Students opened your books. |
| They | Third-person plural or singular | their | The players changed their uniforms. |
The selection process has four steps:
- Identify who or what has the relationship.
- Replace that possessor mentally with a subject pronoun.
- Match the pronoun to the possessive form.
- Place the form before the relevant noun.
For The manager revised ___ schedule, identify the manager as he, she, or they, depending on the known reference. The sentence becomes his schedule, her schedule, or their schedule. The schedule itself does not control the choice.
Does the Possessed Noun Change the Form?
No. The possessed noun does not determine the possessive adjective. English uses the same form before singular and plural nouns: my book, my books, their office, and their offices.
| Possessive form | Singular noun | Plural noun | Correct principle |
|---|---|---|---|
| my | my desk | my desks | The possessor is I |
| his | his ticket | his tickets | The possessor is he |
| our | our plan | our plans | The possessor is we |
| their | their child | their children | The possessor is they |
This is a frequent beginner error. Writers sometimes choose their because the object is plural, but their depends on the possessor, not the object.
Where Do Possessive Adjectives Go in a Sentence?
A possessive adjective usually comes before the complete noun phrase it determines. Adverbs and ordinary adjectives may occur between the possessive form and the noun, as in her exceptionally careful explanation or our two new computers.
Common patterns include:
- Possessive adjective + noun: your decision
- Possessive adjective + adjective + noun: your final decision
- Possessive adjective + number + adjective + noun: their two large dogs
- Verb + possessive adjective + noun: She opened her notebook.
- Preposition + possessive adjective + noun: The message arrived on my phone.
Possessive adjectives normally cannot appear after a linking verb without a noun. That laptop is my is incorrect because my requires a following noun. Use That laptop is mine or That is my laptop.
A possessive adjective can also occur inside a longer phrase: the student in our advanced writing class. The entire phrase is a noun phrase, but our still determines only advanced writing class.
Can an Article Come Before a Possessive Adjective?
No. A possessive adjective and an article generally compete for the same determiner position. Use the report, a report, or my report, but not the my report or a my report.
Other determiners can sometimes combine with possessive forms in special constructions, especially all, both, and half: all my notes, both your answers, and half our budget. These words do not function like the articles a and the in those phrases.
Possessive Adjectives Examples by Meaning
Possessive adjectives express more than legal ownership. Context determines the relationship.
| Relationship | Example | Meaning of the relationship |
|---|---|---|
| Ownership | She sold her bicycle. | The bicycle belongs to her |
| Family | I visited my uncle. | The uncle is related to me |
| Membership | Our club meets weekly. | We belong to the club |
| Origin | Their accent sounded familiar. | The accent is associated with them |
| Authorship | He published his article. | He wrote or produced the article |
| Physical association | The dog hurt its paw. | The paw belongs biologically to the dog |
Possessive adjectives can identify body parts, clothing, documents, devices, and abstract ideas. English often uses a possessive form where some languages use a definite article, especially with body parts: She washed her hands and He injured his knee.
The relationship can be temporary or descriptive rather than permanent. In our current problem, our means the problem affects or concerns us; it does not mean we own the problem.
Possessive Adjectives vs. Possessive Pronouns
Possessive adjectives modify a following noun, while possessive pronouns replace an entire noun phrase. The pairs are related, but their sentence positions differ.
| Function | Possessive adjective | Possessive pronoun | Example |
|---|---|---|---|
| First-person singular | my | mine | My coat is wet; the blue coat is mine. |
| Second-person singular or plural | your | yours | Your seat is here; the seat is yours. |
| Third-person masculine | his | his | His answer is correct; the answer is his. |
| Third-person feminine | her | hers | Her file is open; the file is hers. |
| Third-person nonhuman | its | Rare standalone use | The machine has its manual. |
| First-person plural | our | ours | Our room is larger; the room is ours. |
| Third-person plural | their | theirs | Their plan won; the plan is theirs. |
Compare these sentence frames:
- This is my seat.
- This seat is mine.
- That is their decision.
- That decision is theirs.
The phrase my mine coat is incorrect because it places two forms in the same determiner role. Choose my coat or the coat is mine.
Why Is His Both Forms?
His functions as both a possessive adjective and a possessive pronoun. In his jacket, his determines the noun. In The jacket is his, his stands alone and replaces his jacket.
The surrounding syntax reveals the function. A following noun indicates determiner use; a standalone position after a linking verb indicates pronoun use.
How Does Whose Work?
Whose asks which person or group has a relationship to a noun. It functions as an interrogative possessive determiner in Whose phone is ringing? and as a possessive pronoun in Whose is this?
Examples include:
- Whose notebook did you find?
- Whose responsibility is this?
- Whose keys are on the table?
- Whose are these documents?
Do not confuse whose with who’s. Whose expresses possession or association, while who’s contracts who is or who has: Whose coat is this? versus Who’s wearing that coat?
The same distinction applies in formal writing, emails, and examinations. An apostrophe does not automatically indicate possession, and whose is the possessive form of who.
What Is the Difference Between Its and It’s?
Its is a possessive adjective meaning associated with or belonging to an inanimate entity, animal, organization, or situation. It’s is a contraction of it is or it has, so the two forms cannot substitute for each other.
| Form | Expansion or meaning | Correct example | Replacement test |
|---|---|---|---|
| its | Possessive determiner | The phone lost its signal. | No expansion |
| it’s | It is | It’s unusually quiet. | It is unusually quiet |
| it’s | It has | It’s stopped working. | It has stopped working |
| its | Possession in a noun phrase | The firm changed its policy. | Followed by a noun |
Use the replacement test: if it is or it has fits, write it’s. If the word comes before a noun and identifies an associated thing, write its.
The apostrophe rule is counterintuitive because apostrophes mark possession in many ordinary nouns, such as the company’s policy. Pronouns follow a different convention: its has no apostrophe, just as yours, hers, ours, and theirs do not.
How Do Your, You’re, Their, There, and They’re Differ?
Your and their are possessive adjectives; you’re and they’re are contractions; there usually identifies a place, existence, or grammatical position.
| Form | Category | Meaning | Example |
|---|---|---|---|
| your | Possessive adjective | Associated with you | Check your email. |
| you’re | Contraction | You are | You’re ready. |
| their | Possessive adjective | Associated with them | Their office is closed. |
| there | Adverb or existential marker | In that place or existence | Put it there. |
| they’re | Contraction | They are | They’re waiting. |
A second substitution test resolves most errors. Replace you’re with you are and they’re with they are. If the expanded sentence fails, use your or their.
Singular they takes their: Every applicant must upload their résumé. This usage is established in contemporary English for a person whose gender is unknown, irrelevant, or nonbinary. It also avoids the awkwardness of his or her in many workplace instructions.
Can a Possessive Adjective Refer to a Company or Animal?
Yes. Use its for a nonhuman singular antecedent when the entity is treated grammatically as it: The company updated its website and The cat licked its paw. Use their for plural entities: The companies updated their websites.
Organizations can also take their in varieties of English that treat collective nouns as plural, particularly British English: The committee have published their findings. American English commonly treats a company or committee as singular: The committee has published its findings.
| Antecedent | Common American English pattern | Common alternative |
|---|---|---|
| the company | its policy | their policy in some styles |
| the committee | its decision | their decision with plural treatment |
| the dog | its collar | their collar when gender is personalized |
| the dogs | their collars | Not normally its collars |
Choose a style and apply it consistently. The main error is not the variety itself, but switching between singular and plural treatment in one document.
What Alternatives Can Replace a Possessive Adjective?
English can express possession with a possessive noun, an of phrase, or a noun modifier. The best choice depends on animacy, formality, length, and meaning.
| Structure | Example | Typical use | Main limitation |
|---|---|---|---|
| Possessive adjective | our schedule | Known speaker group | Requires a pronoun-based possessor |
| Apostrophe possessive | the manager’s schedule | People, animals, organizations | Long possessors may sound heavy |
| Of phrase | the roof of the building | Objects and long phrases | Can sound formal or less direct |
| Noun modifier | company policy | Categories and institutional labels | May express type, not ownership |
| Possessive pronoun | the schedule is ours | Avoiding repeated nouns | Cannot normally precede a noun |
Apostrophe possessives are natural with people: Maria’s laptop. The of construction is often clearer with long or inanimate phrases: the end of the three-hour meeting. A noun modifier can change the meaning: school bus usually means a bus for school use, not a bus owned by a school.
What Are the Most Common Possessive Adjective Errors?
The most common errors involve confusing a possessive determiner with a contraction, selecting a form from the possessed noun, or combining incompatible determiners.
- Wrong: The company changed it’s name.
Correct: The company changed its name. - Wrong: Your going to lose you’re place.
Correct: You’re going to lose your place. - Wrong: The students submitted there essays.
Correct: The students submitted their essays. - Wrong: The child put her toys in his box.
Correct: Choose a consistent antecedent: The child put her toys in her box or their box. - Wrong: This is my mine.
Correct: This is mine or This is my book. - Wrong: The two team changed its uniforms.
Correct: The two teams changed their uniforms.
Why Does Agreement Become Difficult?
Agreement becomes difficult when a noun phrase contains several possible antecedents. In The daughter of the neighbors lost her keys, her refers to daughter, not neighbors, because the daughter is the grammatical possessor being described.
Professional editing should identify the intended possessor before choosing the form. If the reference is unclear, repeat the noun: The daughter lost the daughter’s keys is grammatical but awkward, so rewrite as The daughter lost her keys after making the antecedent clear in context.
How Can You Learn the Forms Quickly?
Most learners can memorize the seven core forms in 1-2 hours, but automatic accuracy typically requires 2-4 weeks of repeated reading, correction, and sentence production. A structured 14-day plan costs $0 if it uses a notebook, existing texts, and free grammar references.
| Period | Practice task | Typical time | Success measure |
|---|---|---|---|
| Days 1-2 | Memorize pronoun-to-form pairs | 15 minutes daily | 7 of 7 forms recalled |
| Days 3-5 | Label objects with noun phrases | 10 minutes daily | 20 accurate phrases |
| Days 6-8 | Correct homophone sentences | 15 minutes daily | 90% accuracy |
| Days 9-11 | Write personal and workplace examples | 15 minutes daily | 12 original sentences |
| Days 12-14 | Edit a paragraph and read aloud | 20 minutes daily | No determiner errors |
Begin with the alignment I-my, you-your, he-his, she-her, it-its, we-our, they-their. Then practice contrast pairs such as my/mine, your/yours, and their/theirs. Finish each session by writing one sentence with a contraction so the apostrophe distinction becomes active rather than purely memorized.
Free references include the British Council’s English-learning materials, Purdue Online Writing Lab, and reputable learner dictionaries such as Cambridge Dictionary. Paid workbooks commonly cost $15-$30, while language-learning subscriptions often cost approximately $7-$13 per month, depending on the provider and plan.
How Should Different Writers Use Them?
Beginners should prioritize form selection and placement. Label visible objects with phrases such as my desk, our kitchen, and their books, then convert each phrase into a full sentence.
Intermediate writers should dedicate one editing pass to homophones. Search specifically for its, it’s, your, you’re, their, there, and they’re, because spellcheckers often cannot determine the intended meaning from grammar alone.
Professional writers should prefer clear, inclusive constructions. Employees must submit their reports by Friday is usually more readable than Every employee must submit his or her report by Friday. The plural rewrite also avoids forcing a binary choice when the employee’s gender is unknown.
A useful practitioner rule is to edit pronouns after editing nouns. First establish each antecedent, then select his, her, its, or their. Pronoun correction without antecedent analysis creates sentences that are grammatically polished but semantically ambiguous.
FAQ
Is my an adjective or a pronoun?
My is traditionally called a possessive adjective, but modern grammar commonly calls it a possessive determiner. It modifies a following noun in phrases such as my answer. The related possessive pronoun is mine, as in The answer is mine, where the word replaces the noun phrase.
Do possessive adjectives have plural forms?
Possessive adjectives do not change form according to the number of the possessed noun. Write my friend and my friends, not mys friends. The form changes only when the possessor changes, as in my friends versus their friends.
Can I say theirs book or mine car?
No. Theirs and mine are possessive pronouns, so they stand alone: The book is theirs and The car is mine. Before a noun, use the possessive adjectives their and my: their book and my car.
Is whose formal English?
Whose is standard in both spoken and written English. It can ask about ownership, authorship, responsibility, or association, as in Whose report is this? The form is appropriate in casual conversation, academic writing, and professional communication.
Should a company take its or their?
Use its when the company is treated as a singular entity, which is common in American English: The company released its results. Use their when the organization is treated as a plural group, a pattern more common in British English or when referring to the people within the organization.
How can I test whether a word is possessive?
Check what follows the word and apply the contraction test. If a noun follows, my, your, his, her, its, our, or their may be the correct determiner. If it is, it has, you are, or they are can replace the word, use the corresponding contraction instead.
The Bottom Line
Possessive adjectives show who or what is connected with a noun, and the seven core forms are my, your, his, her, its, our, and their. Select the form from the possessor, place it before the noun, and use mine, yours, hers, ours, or theirs when a possessive pronoun must stand alone. Careful writers also distinguish its from it’s, your from you’re, and their from there and they’re. Possessive adjectives become reliable through short, repeated editing and sentence-building practice.
