What is an interrogative pronoun?

An interrogative pronoun is a pronoun used to ask a question. They are used to replace a noun or noun phrase that is the subject or object of the question.

Here are the common interrogative pronouns in English:

* Who: Used for people.

* *Who is coming to the party?*

* Whom: Used for people as the object of a verb or preposition (though it's often replaced by "who" in informal English).

* *Whom did you invite?*

* Whose: Used to show possession.

* *Whose book is this?*

* What: Used for things or ideas.

* *What is your favorite color?*

* Which: Used for choosing from a limited set of options.

* *Which shirt should I wear?*

Examples:

* Who wrote this song?

* Whom did you call?

* Whose car is parked in the driveway?

* What is the capital of France?

* Which one of these cakes did you bake?

Remember: Interrogative pronouns always start a question.
