English grammar can sometimes be confusing, especially when two words sound exactly alike but have completely different meanings. One of the most common examples is “whos” vs “whose.” Many writers accidentally leave out an apostrophe or use the wrong word entirely, leading to grammar mistakes in emails, essays, social media posts, and professional writing.
The good news is that the difference between these words is actually simple once you understand their roles in a sentence. “Whose” is a correct English word used to show possession, while “whos” without an apostrophe is generally incorrect in standard English.
Most of the time, people actually mean to write “who’s,” which is a contraction of “who is” or “who has.”

“Whos” is usually incorrect.
In many cases, people actually mean:

when they actually mean:

Easy Trick to Remember the Difference
Whose = Possession
Think:
- whose car
- whose idea
- whose jacket
It works like:
- his
- her
- their
Who’s = Who Is
Replace “who’s” with:
- who is
or - who has
If the sentence still makes sense, “who’s” is correct.
Example
- Who’s coming today?
→ Who is coming today?
This works perfectly.
