Pronunciation

Forms

boyau m (plural boyaux)[1] Old French feminine buele (1080), masculine boel and boiel (about 1160); boyau about 1340.[2][3][4]

Etymology

It is inherited from Old French boiel, inherited from Latin botellus (“small sausage”), which seems to have taken the sense “intestine” only in Medieval Latin (802).[2][5][6][1] The oldest form, the feminine buele, comes from the neuter plural *botella.[2] The Latin word is the diminutive of botulus (“blood sausage”), probably not Roman in origin and perhaps borrowed from Oscan.[2] The French word ousted buille, the outcome of the base word.[2]

Cognate with Old Occitan budel, Catalan budell and Italian budello, whose ⟨u⟩ is of obscure origin.[4][6]

Earliest recorded meaning

It is first found as the feminine buele in the Chanson de Roland (1080), of a man's bowels: Defors son corps veit gesir la buele “he sees his bowels lying outside his body”.[2][3][4]

Semantic evolution

All the old forms named the intestines of animals in general.[2] As in Medieval Latin, the word passed into technical use for a cord made from gut, used in surgery and then in music, as in the familiar racler le boyau “to play a stringed instrument badly” (1623); gut for tennis rackets came in the 20th century.[2]

By analogy boyau named a winding military trench (1676), then any long narrow passage (1690), a conduit or hose, and since 1904 the tubular tyre of a racing bicycle, made of a single casing.[2][3][7] The familiar se boyauter “to split one's sides laughing” dates from 1901, and tord-boyaux, a very strong brandy, from 1855.[2]
