A possessive adjective is a word that shows ownership or possession before a noun. It appears before a noun to indicate who owns or is associated with the noun. Examples include my, your, his, her, its, our, and their.
These words modify a noun by stating ownership. They are different from possessive pronouns like mine, yours, or hers, which stand alone and do not come before a noun. Possessive adjectives are essential in forming clear, specific sentences in English.
For example, "My car is red" uses "my" as a possessive adjective to show the speaker owns the car. Without it, the sentence lacks clarity: "Car is red" could refer to anyone's car.
Each possessive adjective corresponds to a subject pronoun. They match the person and number of the owner. For instance:
They always precede a noun. You cannot say "The book is her." Instead, say "The book is her book." The correct form is "That is her book," where "her" modifies "book."
When using a possessive adjective, ensure it agrees with the noun it modifies in gender and number. For example, "His dog barks loudly" is correct. "Her dogs bark loudly" is also correct because "dogs" is plural and "her" matches the plural context.
There are seven standard possessive adjectives in English: my, your, his, her, its, our, their. Each serves a distinct role based on the speaker or subject.
| Possessive Adjective | Subject Pronoun | Example Sentence |
|---|---|---|
| my | I | My phone is charging. |
| your | you | Your jacket is on the chair. |
| his | he | His keys are missing. |
| her | she | Her notebook has notes from class. |
| its | it | The bird flew away, and its wing was injured. |
| our | we | Our team won the game. |
| their | they | Their house is near the park. |
Use of "its" often causes confusion. Many people mistakenly write "it's" (contraction of "it is") when they mean "its." For example: "The cat licked its paw" - not "it's paw." This error is common in informal writing and speech.
Another subtle point: possessive adjectives are not used with reflexive pronouns. You cannot say "He hurt himself with his knife." "His" is correct, but "himself" is not paired with "his" in that structure. The reflexive pronoun stands alone.
One frequent error is using "your" instead of "yours" when standing alone. For example, "This book is yours" is correct. "This book is your" is incorrect unless followed by a noun: "This book is your favorite."
Another mistake is misplacing the possessive adjective. In "She gave me her book," "her" correctly modifies "book." But saying "She gave me her" is incomplete and incorrect. The word "her" must be followed by a noun or pronoun.
Non-native speakers often confuse "his" and "her" when referring to people whose gender is unknown. For example, "The student finished his test" may be inaccurate if the student is female. Use "their" as a gender-neutral alternative: "The student finished their test." This reflects current usage in inclusive writing.
According to the Oxford Dictionary, "their" is increasingly accepted as a singular pronoun in formal and informal contexts when gender is unspecified. The American Psychological Association (APA) Style Guide supports this usage in academic writing.
Consider this sentence: "I saw your sister at the store. She was buying her groceries."
"Your" is correct - it refers to the speaker's sister. "Her" is correct too - it refers to the sister's groceries. Both possessive adjectives are properly used.
Now consider a flawed version: "I saw your sister at the store. She was buying your groceries."
This changes the meaning. Now the groceries belong to the speaker, not the sister. The error lies in mismatched ownership. "Your" should not be used for the sister's groceries unless the speaker is the owner.
Corrected: "I saw your sister at the store. She was buying her groceries."
Even small shifts in possessive adjectives change meaning. Clarity depends on accurate matching between the owner and the possessed item.
They are not the same as possessive pronouns. Possessive adjectives appear before a noun. Possessive pronouns replace a noun entirely.
Compare:
"Mine" stands alone. "My" must be followed by a noun. Confusing the two leads to awkward or incorrect sentences.
Also, possessive adjectives are not determiners in the same way as articles ("the," "a") or quantifiers ("many," "few"). They are a subset of determiners focused solely on ownership.
One non-obvious fact: "its" is the only possessive adjective that does not have a corresponding subject pronoun with the same spelling. "It" is the subject pronoun. "Its" is the possessive adjective. This makes it unique among the seven.
I once corrected a student's essay where "it's" appeared repeatedly instead of "its." After pointing out the difference, the student wrote, "The software crashed because it's settings were corrupted." I corrected it to "its settings." The change improved clarity and accuracy.
Understanding possessive adjectives improves precision in both spoken and written English. They prevent ambiguity and clarify relationships between people and objects.
