What Does “Whose” Mean?
Whose is a possessive word. It asks or tells who owns something.
It answers the question:
To whom does this belong?
Examples
- Whose jacket is this?
- I know whose phone rang.
- Whose dog is barking outside?

In every example, whose talks about ownership.
What Does “Who’s” Mean?

Why Do People Confuse Whose and Who’s?
These words sound exactly alike.
They are called homophones.
Since they have the same pronunciation, many writers choose the wrong spelling.
Another reason is that many possessive words use apostrophes.
For example:

- Sarah’s car
People think who’s should also show possession.
However, English is different here.
Whose never uses an apostrophe.
