Who is a subject pronoun (used for the person performing an action), while whom is an object pronoun (used for the person receiving an action). The words whose and who’s may sound identical, but their meanings and usage are completely different.
Who's and whose are easy to confuse. Who's means who is or who has. Whose shows possession (e.g., Never trust a doctor whose plants have died).
The correct choice is whose. So what is the difference between whose and who's? The word whose is the possessive form of the pronoun who. It is used in questions to ask who owns something, has something, etc. Who becomes whose just like he and she become his and her. Below are some examples of whose in sentences:
Many English learners feel confused about Who’s, Whose, and how to use them correctly. These words look similar, but they have different meanings and uses. In this blog post, you will learn how “who’s” is a short form of “who is” or “who has,” and how “whose” shows possession.
Since who’s and whose are pronounced the same way, they are often confused in writing. Here’s a simple trick: if you can use “who is” or “who has” instead and still have the sentence make sense, use who’s; otherwise, use whose.
Who’s is a contraction (shortened form) of “who is” or “who has.” Whose book is this? Who’s the man wearing a suit? Philip, whose job was very demanding, needed a holiday. Who’s eaten at this restaurant before? Whose is the possessive form of “who.”
Whose is a possessive pronoun that you should use when you’re asking or telling whom something belongs to. Who’s is a contraction made up of the words “who” and “is” or “who” and “has”. The key to using “whose” vs “who’s” correctly is to understand the word at the root of each.
