Question

answerquestionswh-question
An interrogative sentence is a sentence that asks a question. Interrogative sentences are generally divided between yes–no questions, which ask whether or not something is the case (and invite an answer of the yes/no type), and wh-questions, which specify the information being asked about using a word like which, who, how, etc.
Questions are often conflated with interrogatives, which are the grammatical forms typically used to achieve them.
