Interrogative adjectives are a special type of adjective used to ask questions or seek information about nouns. They include “which,” “what,” and “whose.”

These adjectives modify nouns by introducing uncertainty or inquiry into the sentence, often at the beginning of a question.

What Is An Interrogative Adjective

For example, in “Which book do you want?” the word “which” is an interrogative adjective modifying “book” and indicating a question about selecting a specific book.

Interrogative adjectives play a crucial role in forming questions and clarifying the nature of the nouns they modify, facilitating effective communication and information gathering.
