Teaching possessive adjectives was one of my first breakthroughs as an ESL teacher. I remember a student asking, “Teacher, is ‘my’ a possessive adjective or a possessive pronoun?” — and I realized the confusion happens because both words look similar and feel interchangeable. They’re not. Once you understand the core rule (adjectives come before nouns; pronouns stand alone), the whole category clicks into place.
The seven possessive adjectives make up almost all ownership and possession in English, and understanding them grouped by person and number is the key. You’ll shows how they differ from possessive pronouns, plus plenty of examples, dialogues, and a quiz to lock in the pattern.
Key Takeaways
- Always come before the noun — “my book,” “your house,” “their car” (never after).
- Seven core words cover all persons: my, your, his, her, its, our, their.
- Possessive adjectives ≠ possessive pronouns — “my” (adjective) vs. “mine” (pronoun standing alone).
- Agree with the possessor, not the thing owned — “his car” (male) and “her car” (female), same noun.
- No apostrophe — “its” (possession) not “it’s” (it is); “their” not “they’re” or “there”.
What Are Possessive Adjectives?
Possessive adjectives are words that modify (describe) nouns and show ownership or belonging. They always come before the noun they modify and answer the question “whose?” In my classroom I call them the “ownership markers” because they immediately tell you who something belongs to.
Example sentences:
This is my textbook. (The book belongs to the speaker.)
Is this your pencil? (The pencil belongs to the person being spoken to.)
Their dog is barking outside. (The dog belongs to them.)
The Seven Possessive Adjectives
| Possessive Adjective | Person / Number | Example Sentence |
|---|---|---|
| My | 1st person singular (I) | My sister is a doctor. |
| Your | 2nd person singular / plural (you) | Is this your phone? |
| His | 3rd person singular masculine (he) | His car is parked outside. |
| Her | 3rd person singular feminine (she) | Her apartment is on Fifth Avenue. |
| Its | 3rd person singular neuter (it) | The cat licked its paw. |
| Our | 1st person plural (we) | Our house is on the corner. |
| Their | 3rd person plural (they) | Their children are playing in the park. |
Possessive Adjectives vs. Possessive Pronouns
This is where learners often get tangled up. Possessive adjectives and possessive pronouns both show ownership, but they behave very differently in sentences.
Possessive adjectives always come before a noun:
Example 1: “My phone is ringing.” (“My” modifies “phone”)
Example 2: “Her keys are on the table.” (“Her” modifies “keys”)
Possessive pronouns stand alone — no noun after them:
Example 1: “That phone is mine.” (Not “my” — “mine” stands by itself)
Example 2: “Are these keys hers?” (Not “her” — “hers” stands by itself)
| Possessive Adjective | Example (with noun) | Possessive Pronoun | Example (without noun) |
|---|---|---|---|
| My | My book is on the desk. | Mine | The book on the desk is mine. |
| Your | Your jacket is in the closet. | Yours | The jacket in the closet is yours. |
| His | His car needs a wash. | His | This car is his. (his = both adjective & pronoun) |
| Her | Her apartment is beautiful. | Hers | The apartment is hers. |
| Its | The dog wagged its tail. | Its | The tail is its. (rare in practice) |
| Our | Our team won the match. | Ours | The victory is ours. |
| Their | Their house is big. | Theirs | That big house is theirs. |
Quick test: If the noun is missing and the sentence still makes sense, you need a pronoun not an adjective. “This is my” sounds incomplete; “This is mine” works perfectly.
Using Possessive Adjectives Correctly
Rule 1: Always Before the Noun
The cardinal rule of possessive adjectives is placement. They must come directly before the noun (or noun phrase) they modify. This is non-negotiable.
✓ Correct: My best friend lives in Boston.
✗ Incorrect: My friend best lives in Boston. (adjective placement is wrong)
✓ Correct: Their old dog is sleeping.
✗ Incorrect: Their dog old is sleeping.
Rule 2: Agree With the Possessor, Not the Thing
A common confusion: students think the possessive adjective should match the noun that follows. It doesn’t. The possessive adjective matches the owner (the possessor), not the thing owned.
Example: Maria has a cat. We say “her cat” (because Maria = female/she), not “his cat” — even if the topic is switching to another person later.
✓ Correct: Tom and Sarah each have a car. His car is blue. Her car is red.
✗ Incorrect: Tom and Sarah each have a car. Their cars are blue and red. (Vague — which car belongs to whom?)
Rule 3: No Apostrophe With “Its”
This is the spelling trap every learner faces. “Its” (possessive adjective) is spelled without an apostrophe. “It’s” (with apostrophe) is short for “it is.” They sound identical but mean totally different things.
✓ Correct: The dog wagged its tail. (The tail belongs to the dog.)
✗ Incorrect: The dog wagged it’s tail. (This means “it is tail” — nonsensical.)
✓ Correct: It’s raining outside. (It is raining.)
✗ Incorrect: Its raining outside. (The rain possesses something? No.)
Memory trick: Think of “its” like “his” or “her.” You don’t write “hi’s book” or “he’s book” with an apostrophe (that would mean “he is book”). Same rule for “its.”
Sample Dialogues
Ana: Is this your notebook?
Leo: No, that’s not mine. I think it’s Maria’s. Her notebooks all have her name on them.
Ana: What about that one on the shelf?
Leo: That’s mine. I can tell by the sticker. My brother and I always use different stickers.
Ana: And the blue ones — are those theirs?
Leo: Yes, those are their notebooks.
Common Mistakes Learners Make
✗ Incorrect: My phone number is 555-1234, and your phone number is 555-5678. His number is not mine.
✓ Correct: My phone number is 555-1234, and your phone number is 555-5678. His is different.
Why: Once you’ve said “phone number,” you don’t need to repeat it. Use the possessive pronoun “his” to stand alone.
✗ Incorrect: The cat licked it’s paw.
✓ Correct: The cat licked its paw.
Why: “Its” (possession) has no apostrophe. “It’s” = “it is.”
✗ Incorrect: Their dog’s are playing in the yard.
✓ Correct: Their dogs are playing in the yard.
Why: “Their” is a possessive adjective (no apostrophe). “Their dogs” = the dogs that belong to them.
✗ Incorrect: I love you’re cooking.
✓ Correct: I love your cooking.
Why: “Your” = possessive adjective. “You’re” = “you are.”

Frequently Asked Questions
Are possessive adjectives the same as possessive pronouns?
No. Possessive adjectives modify nouns and always come before them (“my cat”). Possessive pronouns stand alone without a noun (“That cat is mine”). The difference is in their position and function, not meaning.
Is “its” or “it’s” correct when showing possession?
“Its” is correct for possession. “It’s” is short for “it is.” Think: The dog licked its paw (the paw belongs to the dog), but It’s raining (it is raining).
Can you use “your” for both singular and plural?
Yes. In modern English, “your” is used for both singular you (one person) and plural you (multiple people). “Is this your notebook?” (one person) or “Are these your notebooks?” (many people). English used to have “thou” for singular, but that’s archaic.
Does the possessive adjective change if the noun is plural?
No. The possessive adjective itself doesn’t change — only the noun changes. “My book” vs. “My books.” “Their car” vs. “Their cars.” The possessive adjective stays the same.
Why do we say “their” instead of “his or her”?
Modern English uses “their” as a singular, gender-neutral possessive adjective. Instead of “each student must bring his or her notebook,” we now write “each student must bring their notebook.” This is now standard in most style guides.
What’s the difference between “your,” “you’re,” and “youre”?
“Your” = possessive adjective (your book). “You’re” = contraction of “you are” (you’re smart). “Youre” is not a word. The distinction between your and you’re is one of the most common errors in English writing.
