Here are some key features of interrogative sentences:
* Word order: They usually begin with a question word (who, what, where, when, why, how) or an auxiliary verb (do, does, did, can, could, will, would, may, might, shall, should, have, has, had).
* Purpose: To elicit information or clarification.
* Structure: Often structured in a way that seeks a specific answer.
Examples:
* What is your name?
* Where do you live?

Interrogative sentences are an essential part of communication, allowing us to gather information, seek confirmation, and express curiosity.
