Many people pause when writing whose or who’s. The words sound the same, but they do not mean the same thing.
Spellcheck tools sometimes miss the error because both spellings are real English words. That makes the confusion even bigger.
Students, bloggers, and professionals search this question because they want clear and correct writing. One small apostrophe changes the meaning, and using the wrong form can make sentences confusing.
The problem is simple: people mix possession and contraction forms. Since both words sound identical, writers often guess which one to use.
This guide explains the difference in very simple words. You will learn what each word means, why confusion happens, and how to avoid mistakes in emails, essays, and online posts.
By the end, you will confidently know when to use whose and when to use who’s.
Quick Answer
Whose shows possession.
Who’s is short for who is or who has.
Examples:
- Whose phone is this? (possession)
- Who’s coming to the party? (who is)
- Do you know who’s finished the work? (who has)
Quick trick:
If you can replace it with who is, use who’s.
Otherwise, use whose.
The Origin of Whose or Who’s
The word whose comes from Old English and has long been used to show ownership or connection.
The word who’s appeared later as a contraction combining who + is or who + has.
English contractions use apostrophes to replace missing letters. So:
- who is → who’s
- who has → who’s
Confusion happens because both words sound the same when spoken.
