WH Questions are a fundamental part of English grammar. They allow us to request specific information rather than simple yes/no answers. These questions typically begin with WH-words such as what, where, when, who, why, which, whom, and also how.
They help us inquire about people, things, places, time, reasons, and methods, making communication more precise and dynamic.
