“What” questions are a type of grammatical construction in the English language that are used to ask for specific information or to seek clarification. They are formed by using the pronoun “what” and adding the subject of the sentence and the main verb. For example: “What is your name?”, “What did you say?”, “What kind of music do you like?”. These questions are asking for specific information or seeking clarification on a particular subject. The pronoun “what” can also be used to form questions asking for a choice among a group or a reason for something, like “What do you prefer?” or “What’s the reason?”
