Interrogatives are words used to ask questions. They help gather information and can be categorized into different types, such as who, what, where, when, why, and how. Each of these words serves a specific purpose, allowing speakers to inquire about people, objects, places, time, reasons, and methods. In English, interrogatives often begin a sentence and are typically followed by a verb. For example, "What is your name?" or "Where are you going?" Using interrogatives effectively can enhance communication and clarify understanding in conversations.
