Which type of sentence is structured to elicit information or a reply?

The sentence type that is structured to elicit information or a reply is the interrogative sentence. Interrogative sentences are designed to ask questions, prompting the listener or reader to provide an answer. They often begin with question words such as who, what, where, when, why, or how, or they may invert the subject and verb to form a question. This structure inherently invites a response, distinguishing it from other sentence types.

In contrast, declarative sentences make statements, imperative sentences issue commands or requests, and exclamatory sentences express strong emotions or exclamations. None of these sentence types are intended to seek information or responses in the same way that interrogative sentences do.
