Apostrophe Rules. Tip#2: Apostrophes and Possessive Pronouns
Personal pronouns, unlike regular nouns, do not use apostrophes to form possessives. Most writers don’t have trouble with the possessive pronouns my, mine, his, her, and our. It’s your, yours, hers, its, ours, their, and theirs, that tend to cause the confusion. The relative possessive pronoun whose is also frequently the victim of apostrophe abuse. Note that none of these forms uses an apostrophe. In fact, for some of these pronouns, adding an apostrophe forms a contraction instead of a possessive.
