Possessive adjectives show ownership by modifying nouns, like "my book" or "her car." They always come before the noun they describe.
Unlike possessive pronouns ("mine," "yours"), possessive adjectives never stand alone. They must pair with a noun to make sense. For example:
The adjective form ("my") directly precedes the noun ("coat"), while the pronoun form ("mine") replaces both the adjective and noun entirely.
English has seven possessive adjectives, each matching a personal pronoun:
| Person | Adjective Form | Example |
|---|---|---|
| First person singular | my | "I forgot my keys" |
| Second person singular/plural | your | "Is this your backpack?" |
| Third person singular | his/her/its | "She lost her glove" |
| First person plural | our | "We packed our lunches" |
| Second person plural | your | "Did you finish your homework?" |
| Third person plural | their | "They brought their dog" |
Note that "your" covers both singular ("your book") and plural ("your books") contexts, while "their" applies to any group regardless of gender ("their new car").
People often confuse possessive adjectives with contractions or other word forms. For example:
To avoid errors, remember that possessive adjectives never contain apostrophes. The only exception is "its" (no apostrophe), which is easily confused with the contraction "it's."
While possessive adjectives show ownership, other adjectives describe qualities like size ("big"), color ("red"), or emotion ("happy"). For example:
Let's analyze a sentence with multiple possessive adjectives:
"After finding our missing cat under their porch, we thanked their neighbor for helping my sister and me."
Here, "our" (first-person plural), "their" (third-person plural), and "my" (first-person singular) each modify nouns to show possession.
Possessive adjectives are fundamental to clear communication. By mastering them, you'll avoid common mistakes and express ownership accurately.
