the emperor's new clothes
(also the emperor has no clothes)
Used in reference to a situation in which people believe or pretend to believe in the worth or importance of something that is worthless, or fear to point out an obvious truth that is counter to prevailing opinion: is his white canvas a case of the emperor’s new clothes or is it something beautiful, even moving? this is the first time that anyone has stripped his work of its rhetoric and shown that this particular emperor has no clothes
[After the title of the story Kejserens nye klæder (1837) by the Danish writer Hans Christian Andersen (first translated into English as The Emperor's New Clothes in 1846), in which an emperor is tricked into thinking he is wearing beautiful new clothes, which all his courtiers pretend to admire, until a boy points out that he is in fact naked]

Middle English (especially representing the title given to the head of the Roman Empire): from Old French emperere, from Latin imperator 'military commander', from imperare 'to command', from in- 'towards' + parare 'prepare, contrive'.

  • The root of emperor is the Latin word imperare ‘to command’, which is also the ultimate source of empire (Middle English), imperative (mid 16th century), imperial (Late Middle English), and imperious (late 16th century). Latin imperator meant ‘military commander’, which was given as a title to Julius Caesar and to Augustus, the first Roman emperor, and was adopted by subsequent rulers of the empire. In English, emperor first referred to these Roman rulers, and then to the head of the Holy Roman Empire. See also evil
