What does tranquillize mean?
Tranquillize means to make someone or something calm, peaceful, and free from anxiety or disturbance. It is used for both physical and emotional calm: a quiet environment may tranquillize a crowded room, while reassurance or a soothing voice may tranquillize an anxious person. The verb can also be used figuratively for situations that are made less turbulent or threatening. Although precise and authoritative in tone, it is relatively formal and less frequent in ordinary conversation than simpler alternatives such as "calm," "pacify," and "soothe." British and American usage differ mainly in spelling: British English traditionally favors "tranquillize" or "tranquillise," while American English generally uses "tranquilize." The word is useful when the speaker wants to emphasize the deliberate restoration of peace or the removal of agitation rather than merely describe a state of being calm.
