köken: Inherited from Late Latin gulbia, gubia, from Gaulish *gulbiā, from Proto-Celtic *gulbā, *gulbīnos (“beak, bill”). See the late term for more information. Compare Middle Irish gulba (“beak”), English gouge.
köken: Uncertain. * Possibly borrowed from Ancient Greek κέστρον (késtron) or κέστρος (késtros, “sharpness”), from the root of the verb κεντέω (kentéō, “to prick, sting, stab”). * Alternatively, from caed- (“to cut”) + -trum, from Proto-Indo-European *keh₂id-, *kh₂eyd- (“to cut, hew”) + *-trom (“instrumental suffix”), related to Latin caelō (“carve”), caelum (“chisel”).
