busk (n.)youdaoicibaDictYouDict[busk 词源字典]
"strip of wood, whalebone, etc., used in corset-making," 1590s, probably from French busc (16c.), from Italian bosco "splinter," of Germanic origin (see bush (n.)).[busk etymology, busk origin, 英语词源]
busk (v.)youdaoicibaDictYouDict
"to prepare, to dress oneself," also "to go, set out," c. 1300, 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.
busker (n.)youdaoicibaDictYouDict
"itinerant entertainer," 1857, from busk (v.) "to offer goods for sale only in bars and taprooms," 1851 (in Mayhew), perhaps from busk "to cruise as a pirate," which was used in a figurative sense by 1841, in reference to people living shiftless and peripatetic lives. Busker has been mistakenly derived from buskin in the stage sense.
buskin (n.)youdaoicibaDictYouDict
"half boot," c. 1500, origin unknown. 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 a likely candidate in Spanish borcegui, earlier boszegui

Figurative senses in English relating to tragedy 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, the low shoe worn by comedians. Related: Buskined.
busking (n.)youdaoicibaDictYouDict

bust (n.1)youdaoicibaDictYouDict
1690s, "sculpture of upper torso and head," from French buste (16c.), from Italian busto "upper body," from Latin bustum "funeral monument, tomb," originally "funeral pyre, place where corpses are burned," perhaps shortened from ambustum, neuter of ambustus "burned around," past participle of amburere "burn around, scorch," from ambi- "around" + urere "to burn." Or perhaps from Old Latin boro, the early form of classical Latin uro "to burn."
