What is an Interrogative Pronoun?

Interrogative Pronoun Definition: An Interrogative Pronoun is a word used to ask questions about people, places, things, or ideas. Interrogative pronouns help us gather information and seek clarification.

Why are Interrogative Pronouns Important? They are essential for asking questions, gathering information, and engaging in meaningful conversations. Without interrogative pronouns, we wouldn't be able to ask "who," "what," "which," or "whose."

Function in Grammar

Interrogative pronouns are used to ask questions and gather specific information. They always appear at the beginning of questions and help us identify what kind of information we're seeking. For example:

  • Who - asks about people
  • What - asks about things, ideas, or actions
  • Which - asks about choices or options
  • Whose - asks about possession or ownership
  • Whom - asks about people (object form, less common)

Interrogative Pronoun vs Interrogative Adjective: Interrogative pronouns replace nouns in questions, while interrogative adjectives modify nouns (Which book do you want?).
