Clarity

Using the correct form of "who" or "whose" can help to make your writing clearer and more precise. By using "who" when referring to a person and "whose" when showing ownership, you can avoid confusion and ensure that your meaning is understood by your readers.

Common Mistakes

One common mistake is using "who's" instead of "whose." "Who's" is a contraction of "who is" or "who has," while "whose" is a possessive pronoun. For example, "Who's book is this?" is incorrect, and should be "Whose book is this?" Another common mistake is using "who" instead of "whom" in formal writing. "Who" is used as the subject of a sentence, while "whom" is used as the object.

Conclusion

In conclusion, "who" and "whose" are both important pronouns in the English language that serve different purposes. "Who" is used to refer to a person or people, while "whose" is used to show ownership or possession. By understanding the differences between these two pronouns and using them correctly in your writing, you can improve the clarity and precision of your communication.
