Girls or Girl’s: What’s the Difference and When Should You Use Each?

Have you ever stopped while writing and wondered whether to use girls or girl’s? It’s a common grammar question because both words look similar, but they have completely different meanings. The small apostrophe makes a big difference, changing a word from a simple plural noun into a possessive one.

If you’ve ever written phrases like girls school, girl’s school, or girls’ school and felt unsure, you’re not alone. This guide explains the difference between girls or girl’s with easy rules, practical examples, common mistakes, and helpful memory tips so you can use each form correctly every time.

Quick Answer

• Girls = the plural form of girl (more than one girl).
• Girl’s = the singular possessive form (something belongs to one girl).
• Girls’ = the plural possessive form (something belongs to multiple girls).

Examples:
