The Different Meanings and Usages of Who's vs Whose
Both who's and whose come from the interrogative pronoun who. They are hard to keep straight because they sound exactly the same when you say them out loud. However, the two spellings have two very different meanings and usages in English grammar.
Meanings and Usage of Who's
Who's with the apostrophe s is the contraction that is short for “who is.” This is similar to what's, which is the contraction for “what is.”
This form of the word who is often used when asking questions, as in:
- Who's going to the store with me?
This version of who's could easily be replaced with “who is.” Thus, you need the version with the apostrophe s. Here are some more example sentences:
- The teacher needs to know who's missing the assignment.
- Who's planning to take a vacation over Christmas break?
- We were visiting the “who's who” of the community to ask them to sign our petition.
The Meanings and Usage of Whose
Whose is the possessive case of the word who. It is a possessive adjective in a sentence when asking or showing possession of something.
According to the Merriam-Webster Dictionary, the word whose means “that which belongs to whom.” This is a rather complex definition, but you can understand the word to mean the possessive form of the word who.
Historically, whose was used only to describe possession by a person or group of people. For example:
- Samantha, whose book was under the couch, was late because she was looking for it.
However, the English language is constantly evolving, and it is now appropriate to use it as the possessive word referring to items belonging to inanimate objects and even places. For example:
- New York, whose lights are always on, is known as the City that Never Sleeps.
- The book, whose cover was torn, was the girl's favorite.
- Whose Line Is It Anyway is a popular comedy show where improv comedians are fed lines and scenarios to act out.
How to Keep Who's vs Whose Straight
A simple trick to keep who's vs whose straight in your writing is to consider the apostrophe as a replacement for missing letters. When you make a contraction of who is, you eliminate the letter i. Thus, you need an apostrophe to show that there is a missing letter.
On the other hand, whose does not have a missing letter. It is the possessive form of the pronoun. The spelling changes help keep the two words distinct from each other.
