Question Words


The words who, whom, whose, which, what, when, where, why and how are used in questions. They show what kind of information is wanted.

Who and whom are pronouns. They act as subject or object in their clauses. When, where, why and how act as adverbs. What, which and whose can be pronouns or determiners.

Question words normally come at the beginning of their clauses. When a question word is the subject, it comes before the verb and do cannot normally be used.
