Question

what is the interrogative adjective?

Answer 1

HEY MATE !
Interrogative adjectives are words similar to interrogative pronouns, but they can’t stand on their own.  In other words, they serve to modify another term, specifically a noun.  The words “which” and “what” are the two interrogative adjectives and are used in interrogative sentences to modify nouns found in the question.

Before we get into interrogative adjectives, let’s take a step back. When you think of an “adjective” what is the first thought that comes to mind?  Yellow flowers?  A beautiful sunset? A fast car?  In the preceding examples, the role the adjectives “yellow,” “beautiful,” and “fast” is attributive, meaning they modify or describe a noun (or a pronoun). They paint a nice picture in our mind.

She filled the vase with yellow flowers.

A beautiful sunset marked the end of a perfect day.

John didn’t care what he received for graduation as long as it was a fast car.

Sometimes adjectives are found in the predicate of a sentence.  In this case the adjective describes a preceding noun and is linked to it with a verb.
