Interrogative Pronouns
Interrogative Pronouns are one of the seven types of pronouns. Pronouns which help to introduce/ask questions are called Interrogative pronouns. Who, which, what, whose, whom (whom is the subject form of who) and how are Interrogative pronouns. All interrogative pronouns begin with ‘Wh’. But, one should know that although words like where, why and when start with wh- they are not Interrogative pronouns.
