1590s, from Middle French desbaucher (“entice from work or duty”), from Old French desbauchier (“to lead astray”), from des- + bauch (“beam”), from Frankish *balko, from Proto-Germanic *balkô, from Proto-Indo-European *bhelg- (“beam, plank”); latter origin of balk.
Evolution of sense unclear; may be literally “to shave/trim wood to make a beam” or may be “to leave/lure someone from a workshop”, Frankish *balko perhaps also meaning “workshop”.
Possible corruption by way of Anglicised French term 'bord' meaning edge, kerb: kerb crawling as a synonym for prostitution. Parallels in modern German: 'Bordsteinschwalbe" (Lit transl: Kerb-stone-swallow or kerb-bird, a prostitute). English words bawd, bawdiness may be similarly connected.
