Question

What is the difference between an interrogative adjective and an interrogative pronoun?

Answer 1

An interrogative adjective asks a question and describes a noun
An interrogative pronoun asks a question, but stands alone (ie, does not describe a noun).

Explanation:

For example:

"Which colour looks better?"

Here, "which" is an interrogative adjective, as it is describing the noun "colour".

"What should I buy you for Christmas?"

Here, "what" is an interrogative pronoun as it is asking a question,
but is NOT modifying a noun; it stands alone.

Some more examples of interrogative adjectives:

• "Whose car is that?"
• "What material is it that you are using?"
• "Which kangaroo jumps higher?"

Some more examples of interrogative pronouns:

• "Who is that?"
• "What are you doing?"
