When learning English, “girls” and “girl’s” can look almost identical, but they have different meanings and grammatical functions. The main difference is simple: “girls” is usually the plural form of “girl,” while “girl’s” is the possessive form, meaning something belongs to or is connected with one girl.
For example, “The girls are playing outside” means more than one girl is playing. On the other hand, “The girl’s bag is blue” means the bag belongs to one girl. Understanding this small punctuation difference can help students, ESL learners, and anyone writing English avoid common grammar mistakes. In this guide, you will learn exactly when to use girls and girl’s, with clear examples and an easy memory trick.
Quick Answer
“Girls” means more than one girl. “Girl’s” means something belongs to one girl or is associated with one girl. Use girls for a plural noun and girl’s for singular possession. For example: “The girls are happy” and “The girl’s dress is beautiful.”
Why Do People Confuse “Girls” and “Girl’s”?
The confusion happens because both words are pronounced similarly in many sentences, but the apostrophe changes the grammar.
- Girl = one female child or young woman
- Girls = more than one girl
- Girl’s = belonging to one girl
Compare:
- The girls are studying. → Several girls are studying.
- The girl’s book is on the desk. → The book belongs to one girl.
The apostrophe in girl’s is important because it shows possession.

Common Mistakes
Mistake 1: Using “girl’s” for a plural
❌ The girl’s are playing outside.
✅ The girls are playing outside.
Why? You are talking about multiple girls, not possession.
Mistake 2: Removing the apostrophe from possession
❌ The girls bag is blue.
✅ The girl’s bag is blue.
Why? The bag belongs to one girl.
Mistake 3: Using “girls” when showing possession
❌ The girls phone is ringing.
If one girl owns the phone:
✅ The girl’s phone is ringing.
If several girls share or collectively own the phone, you may need a different structure depending on the meaning.
Memory Trick: “S” or “’S”?
A simple trick can help:
Girls = many girls
Girl’s = one girl owns or has something
Think:
No apostrophe = plural
Apostrophe + s = one girl’s possession
For example:
- Girls → many
- Girl’s → one + belongs to her
