An interrogative word or question word is a function word used to ask a question, such as what, when, where, who, whom, why, and how. They are sometimes called wh-words, because in English most of them start with wh- (compare Five Ws). They may be used in both direct questions (Where is he going?) and in indirect questions (I wonder where he is going).
