Have you ever typed something like “who’s jacket is this” and felt unsure if it was right? Don’t worry you are not alone. Many people confuse whose or who’s because they sound exactly the same.

Using the wrong one can make your writing look careless, it’s in emails, texts, social media posts, or school essays.

The good news is that the difference is simple. Whose shows ownership, meaning it asks “to whom does this belong?” On the other hand, who’s is a contraction for who is or who has.

This guide will show you the difference, help you avoid mistakes, and use both words correctly every day.

By the end, you’ll never mix them up, and your writing will feel professional and polished.
