Definition & Meaning of "interrogative adjective"

What is an "interrogative adjective"?

An interrogative adjective is an adjective used to ask questions about a noun, typically to inquire about its characteristics or identity. The main interrogative adjectives in English are "which," "what," and "whose." For example, in the question "Which book do you prefer?" the word "which" asks for specific information about the noun "book." Similarly, in "What color do you like?" the adjective "what" inquires about the characteristics of a noun, while "Whose jacket is this?" uses "whose" to ask about ownership. Interrogative adjectives help to form questions that seek clarification or specific details about nouns, making them essential for effective communication.
