Interrogative Pronouns
A pronoun is a word that can take the place of a noun. Based on different form and function in the sentence, pronouns fall into several major categories such as personal pronouns, compound personal pronouns (reflexive), possessive pronouns, relative and interrogative pronouns, demonstrative pronouns, and indefinite pronouns.
When the pronouns who, whom, which, whose, and what are used to begin a question, they are called interrogative pronouns.
