Interrogative Adjectives

An Interrogative adjective modifies a noun or a noun phrase and is similar to the interrogative pronoun. It does not stand on its own and includes words such as, which, what, who, whose, whom, where and so on.

For example:

'What dress are you wearing?' Here, 'what' modifies the noun 'dress' and is the object of the compound verb 'are wearing'.

Other examples:

Which leaves turn color first?

Whose son is he?
