Hers is a possessive pronoun that shows something belongs to a girl or woman. When you say “That backpack is hers,” you mean it belongs to her. It works the same way as “his” for a boy or man, or “theirs” for groups.

Notice that hers doesn't need an apostrophe, even though it shows ownership. You write “The pencil is hers,” not “her's.” This trips up a lot of people because we usually add apostrophes to show possession, like “Sarah's pencil.” But possessive pronouns like hers, his, theirs, and ours are special: they already show ownership without needing that extra punctuation.

You might say “This notebook is mine and that one is hers” or “My science project got a B, but hers won first place.” The word lets you talk about someone's belongings or accomplishments without repeating their name over and over.
