A term used in the classification of sentence functions, typically used to elicit information or a response. Syntactically, in English, a question is a sentence with inversion of the subject and first verb in the verb phrase, commencing with a question word, or ending with a question tag. Some would include the use of sentences with a rising intonation to be a class of question. Semantically, questions express a desire for more information, usually requesting a reply from the listener. The term is usually contrasted with three other major sentence functions: statement, command, and exclamation. In grammatical discussion, questions are usually referred to as interrogative in form. Sentences which contain a subordinate clause which is interrogative in form are sometimes called indirect questions.
