köken: Ultimately a compound of 肋 (abara, “rib bone”, short for 肋骨 (abarabone)) + 肉 (niku, “meat”). It is unclear when the initial a- in abara first disappeared, before or after the formation of this compound. The shortened form bara is now used as an abbreviation for this term baraniku, referring specifically to the meat, rather than abara, referring specifically to the bone.
köken: It is attested as Bordas (personal name, 1355), bõda (“loom comb”) (1405). The meaning "rib" is attested since 1578. Ultimately from a Slavic language; compare Proto-Slavic *bьrdo.
köken: From Proto-Albanian *bren-, from Proto-Indo-European *bʰren- (“to stick out; edge”). Compare Old English brant, Old Norse brattr (“high, sharp”), brand (“sword”), Irish braine (“front part of the ship; guide, leader; edge, border”), Swedish brå (“sharp”). Alternatively a formation from bri.
