An obscenity is any utterance or act that strongly offends the prevalent morality of the time. It is derived from the Latin obscaena (offstage) a cognate of the Ancient Greek root skene, because some potentially offensive content, such as murder or sex, was depicted offstage in classical drama. The word can be used to indicate a strong moral repugnance, in expressions such as "obscene profits" or "the obscenity of war".
