Un-lŭck'y, a.
a. 1. Not lucky; unfortunate; not successful; unhappy; as, an unlucky man; an unlucky adventure; an unlucky throw of dice; an unlucky game.
☞ This word is usually applied to incidents in which success depends on single events, to games of hazard, &c., rather than to things which depend on a long series of events, or on the ordinary course of providence. Hence we say a man is unlucky in play or in a lottery, but not that a farmer is unlucky in his husbandry, or a commander unlucky in the result of a campaign.
Sense 2. Ill-omened; inauspicious.
Hunt me not with that unlucky face. Dryden.
Sense 3. Slightly mischievous; mischievously waggish; as, an unlucky boy; an unlucky wag. [Colloq.]
