| Who’s | Contraction of who is or who has | Who’s coming to the party? 🎉 |
Memory Trick:
- If you can replace it with who is or who has, it’s who’s.
- If it shows ownership, it’s whose.
Why People Confuse Whose and Who’s 🤔

- Both sound the same in speech.
- Whose is less common in casual speech, so it’s often replaced incorrectly by who’s.
- Contractions like who’s make writers forget it’s not about possession.
Quick Tip: Read the sentence aloud. Does it make sense if you expand who’s to “who is”? If yes → who’s. If not → whose.
