Common Mistakes and How to Avoid Them

One of the most common mistakes is using "who's" when "whose" is required, and vice versa. To avoid these errors, it's essential to understand the grammatical function of each term.

Here are some tips to help you avoid common mistakes:

If you can replace "whose" with "of whom," then "whose" is the correct choice. For example, "The book of whom is this?" sounds awkward, so "Whose book is this?" is correct.
If you can replace "who's" with "who is" or "who has," then "who's" is the correct choice. For example, "Who is coming to the party?" can be shortened to "Who's coming to the party?"
