busker (n.)

c. 1300, "to prepare, to dress oneself," also "to go, set out," probably from Old Norse buask "to prepare oneself," reflexive of bua "to prepare" (see bound (adj.2)) + contraction of Old Norse reflexive pronoun sik. Most common in northern Middle English and surviving chiefly in Scottish and northern English dialect. Related boun had the same senses in northern and Scottish Middle English. Related: Busked; busking.

The nautical term is attested from 1660s (in a general sense of "to tack, to beat to windward"), apparently from obsolete French busquer "to shift, filch, prowl," which is related to Italian buscare "to filch, prowl," Spanish buscar (from Old Spanish boscar), perhaps originally from bosco "wood" (see bush (n.)), with a hunting notion of "beating a wood" to flush game. For the "perform in public" sense, see busker.

"half-boot, high laced shoe," c. 1500, of unknown origin. The word exists in different forms in most of the continental languages, and the exact relationship of them all apparently has yet to be determined. The English word is perhaps immediately from Old French broissequin "buskin; a kind of cloth" (14c., Modern French brodequin by influence of broder "to embroider"), or from Middle Dutch brosekin "small leather boot," which is of uncertain origin. OED suggests Spanish borcegui, earlier boszegui.

The figurative senses in English relating to stage tragedy or tragic drama are from the word being used (since mid-16c.) to translate Greek kothurnus, the high, thick-soled boot worn in Athenian tragedy; contrasted with sock (n.1), the low shoe worn by comedians. Related: Buskined.

1851, a slang word, defined variously in Mayhew as selling articles or obscene ballads in public houses, playing music on the streets, or performing as a sort of informal stand-up comedy act in pubs, perhaps from an earlier word meaning "to cruise as a pirate" (see busker).
