Origin: 1300–50; Middle English < French < Late Latin gu(l)bia; compare Old Provençal goja,Spanish gubia; perhaps < Celtic; compare Old Irish gulba sting, Welsh gylf beak, Cornish gilb borer
1350, from O.Fr. gouge, from L.L. gubia, alteration of gulbia "hollow beveled chisel," probably from Gaulish (cf. O.Ir. gulban "prick, prickle," Welsh gylfin "beak"). The verb is 1570, from the noun. Meaning "swindle" is Amer.Eng. colloquial from 1826 (implied in plural n. gougers).
