Pronunciation

Forms

plomb m (plural plombs)[1] Old French plum (1121–1134), plom, plon; the ⟨b⟩ was restored in the 15th century, partly after plomber; it was not pronounced in the 16th century (Palsgrave).[2][3][4]

Etymology

It is inherited from Old French plum, inherited from Latin plumbum (“lead; lead shot; lead pipe”).[5][2][6][7] The origin of the Latin word is obscure; it is probably borrowed from a Mediterranean language, perhaps Iberian, lead coming from Spain.[2][8]

Cognate with Italian piombo, Old Occitan plom, Catalan plom, Spanish plomo, Portuguese chumbo and Romanian plumb.[8][4][9] English plumb, English plunge and English plumber come from French.[8]

Earliest recorded meaning

Philippe de Thaon's Bestiaire (1121–1134) has plum for the metal.[5][2]

Semantic evolution

Old French already used it for objects of lead: the plumb-bob (Villard de Honnecourt, 1260), whence à plomb “vertically” (1552) and later fil à plomb (1751), and the leaden seal of papal bulls (late 14th century), later any seal of lead (1638).[5][2] A plomb was also the lead of a stained-glass window (1454), the sinker of a fishing line (1580) and, from about 1600 (Desportes), shot for a firearm, whence avoir du plomb dans l'aile (1878).[5][2]

Figuratively plomb expresses heaviness: soleil de plomb (Lamartine, 1835), sommeil de plomb (Balzac, 1842), avoir du plomb dans la tête.[5][4] In electricity the plomb de sûreté (1890) or fuse gave faire sauter les plombs and péter les plombs “to lose control” (1980s).[5][2] In 19th-century slang ferme ton plomb ! meant “shut your mouth” (1867).[2][10]
