Definition from Wiktionary, the free dictionary
- (grammar) A pronoun which expresses possession.
- Words like my or their, which modify nouns and cannot stand on their own, are also commonly referred to as "possessive pronouns" (because of their relationship to the personal pronouns). These are also called possessive determiners or possessive adjectives, however, as they are not pronouns in the strict sense.
