Whose vs. Who's: Common Grammar Mistake

Updated on February 28, 2018

Whose vs. Who's

Mixing up "whose" and "who's" is a common grammar mistake. People tend to believe any word with a contraction, such as "who's," is a possessive form. In fact, "whose" is the possessive form, while "who's" is a contraction for "who is" or "who has."

  • Whose – Possessive pronoun. Use when asking or telling whom something belongs to. (ex. Whose phone is this?)
  • Who's – Contraction for "who is" or "who has." (ex. Who's that?)

Use the resources and examples here to help you sort out the differences between the two words and when to use them. Then, take the grammar quiz at the end of this article to see if you have mastered the use of "who's" and "whose" in sentences.

      Great hub. Voted up and useful. I am excited that I got 100% on your quiz. If it had been other easily confused words, I might not have fared so well! :)

      Many of my Thai students actually commit exactly this mistake rather often. They forget that whose is actually the possessive form of who and that who’s actually means "who is" or "who has". Actually I'll use your post as a refresher in class. Thanks for reminding and sharing this!
