Frequently Asked Questions

Can who's be used for possession?

No, who's is strictly a contraction for who is or who has. It never indicates ownership or belonging. For possession, you must always use the possessive form whose in every sentence.

Is whose ever a contraction?

No, whose is a possessive pronoun or determiner. It does not combine two words. It functions like his or her, showing that something belongs to the person or thing being discussed.

How do I remember which one to use?

Remember that the apostrophe in who's replaces missing letters. If you can swap it with who is, it is correct. Otherwise, you need the possessive form whose to show ownership.

Do these rules change in British English?

No, the rules for who's and whose are the same in British and American English. The distinction between the contraction and the possessive form remains consistent across all major English dialects.
