How do I use which in a sentence?
You can use “which” in a sentence as a relative pronoun (e.g., “This book, which I bought used, is an original edition”) or as an interrogative pronoun (e.g., “Which house is yours?”).
Just make sure you don’t mix up wich and which; “which” is the correct spelling. QuillBot’s Grammar Checker can help you avoid this mistake in your sentences.
