Whose is the correct word used to show possession, while whos is incorrect in standard English. This confusion happens because people mix up apostrophe rules, possessive pronouns, and short forms like “who’s.” In fast writing, many drop the apostrophe and write “whos,” which leads to mistakes.
In this guide, you will clearly learn the meaning of “whose,” how it differs from “who’s,” and why “whos” is wrong. You will also understand simple grammar rules, see real examples, and get easy tips to avoid this common English writing mistake.
Quick Answer
The correct spelling is whose.
Use whose to show possession.
Examples:
- Whose book is this?
- She is the girl whose car broke down.
Whos is incorrect and should not be used in correct English spelling.
The Origin of Whose or Whos
The word whose comes from Old English “hwæs,” which was the possessive form of “who.” It has always been used to show ownership or relation.
Over time, English kept this form as a possessive pronoun, similar to “his” or “her.”
The incorrect form “whos” appears because people confuse it with contractions like “who’s” (who is or who has). When the apostrophe is removed, it becomes “whos,” which is not a real word in standard grammar.
British English vs American English Spelling
There is no difference between British and American English for this word. Both use whose.
| Form | British English | American English | Correct |
|---|---|---|---|
| whose | ✔️ Yes | ✔️ Yes | ✔️ Correct |
| whos | ❌ No | ❌ No | ❌ Incorrect |
This rule is the same across all forms of English language usage.
Which Spelling Should You Use?
Always use whose in writing.
- For US audience → use “whose”
- For UK/Commonwealth audience → use “whose”
- For global writing → use “whose”
Avoid “whos” in all contexts. Using the correct possessive form improves clarity and makes your writing look professional and accurate.
Common Mistakes with Whose or Whos
❌ Incorrect: Whos coming to the party?
✔️ Correct: Who’s coming to the party?
❌ Incorrect: Whos bag is this?

Mistaking these forms is a common issue in English grammar rules.
