Answer:
The possessive pronoun being used as an adjective is "their".
Explanation:
In English, the following possessive pronouns are also called possessive adjectives: my, your, his, her, its, our, your, their. They function as an adjective due to the fact that they modify a noun to indicate possession. Also, they cannot stand alone in the sentence; they need to come with the noun they are modifying. In the sentence we are analyzing here, the noun "car" is being modified by "their".
There are possessive pronouns, however, that can stand alone in a sentence. They are the absolute possessive pronouns: mine, yours, his, hers, its, ours, yours, theirs. Let's study the examples:
- Did you see their new car in the parking lot? (possessive adjective)
- Oh, that's not theirs. That one is mine. (absolute possessive pronouns)
