Interrogative Pronouns

• 
  An interrogative pronoun is used to ask a question. The interrogative pronouns are what, which, who, whom, and whose, whatever,  whichever,  whatsoever,  whichsoever
  

Do not confuse interrogative pronouns with interrogative adverbs  (how, when, why, where), which are also used to ask questions. Interrogative adverbs ask about the time, place, reason, or manner an action occurs.
