A question may be either a linguistic expression used to make a request for information, or else the request itself made by such an expression. This information may be provided with an answer.

Questions are normally put forward or asked using interrogative sentences. However they can also be formed by imperative sentences, which normally express commands: "Tell me what two plus two is"; conversely, some expressions, such as "Would you pass the salt?", have the grammatical form of questions but actually function as requests for action, not for answers, making them allofunctional. (A phrase such as this could, theoretically, also be viewed not merely as a request but as an observation of the other person's desire to comply with the request given.)

Famous quotes containing the word question:

    The old question of whether there is design is idle. The real question is what is the world, whether or not it have a designer—and that can be revealed only by the study of all nature’s particulars.
    William James (1842–1910)

    Regarding History as the slaughter-bench at which the happiness of peoples, the wisdom of States, and the virtue of individuals have been victimized—the question involuntarily arises—to what principle, to what final aim these enormous sacrifices have been offered.
    Georg Wilhelm Friedrich Hegel (1770–1831)
