  • noun a criminal, (small-time) gangster. The longer form of the word was in use in the USA by the end of the 19th century; hood became widespread from the 1940s. Many suggestions have been offered as to the origin of the terms. The least unlikely are: a deformation of an Irish surname such as Hoolahan; an altered backslang version of Muldoon; a corruption of ‘huddle-’em’, supposedly the cry of a gang of muggers; and hodalem or hudilump, respectively Bavarian and Swiss dialect terms for a wretch or naughty boy.

Origin & History of “hood”

Ultimately hood and hat are the same word, and both mean etymologically ‘head-covering’. They go back to an Indo-European *kadh- ‘cover, protect’, which in the case of hood produced a west Germanic derivative *khōdaz. from it are descended German hut ‘hat’, Dutch hoed ‘hat’, and English hood. Hoodwink (16th c.) originally meant literally ‘cover someone’s eyes with a hood or blindfold so that they could not see’; the modern figurative sense ‘deceive’ is first recorded in the 17th century.
