Interrogative sentences are types of sentences designed to ask questions and typically require a response or answer. They often begin with question words like 'who', 'what', 'where', 'when', 'why', and 'how', or they may start with auxiliary verbs such as 'is', 'are', 'can', or 'do'. Their structure is crucial in compositional semantics, as they help shape the meaning conveyed in communication by prompting information retrieval.
