Etymology: Apparently < Middle French gobe, goube a mouthful, lump (13th cent. in Old French; rare except in derivatives and set expressions) < an unattested Gaulish reflex of the Celtic base of gob n.² (with an underlying sense ‘mouth, snout, beak’). Compare French gobbe (17th cent.; < gober to swallow whole, literally and figuratively (1549 in Middle French, ultimately of the same origin)).With at one (also a) gob at sense 3b compare Middle French, †French avaler tout de gob to swallow in one mouthful (1579), and (hence) French tout de go straight out, without ceremony (1660).

Etymology: Probably < Irish gob and Scottish Gaelic gob beak, mouth (Early Irish gop muzzle, snout, beak) < a Celtic base of uncertain, probably expressive, origin.It has been suggested that the Celtic base is related to Old Church Slavonic ozobati to consume, to destroy, Lithuanian žėbti to gobble, to covet, but this poses phonological problems.

Etymology: Apparently a variant of gab n.³ (although this is first attested later), probably often interpreted as a sense of gob n.²

Etymology: Origin uncertain. Perhaps either a back-formation < gobbing n.¹ (although this is first attested later with reference to underground mining), or a specific use of gob n.¹ 1, originally with reference to the material used to fill the space. With use with specific reference to the empty space (rather than the filling material) compare goaf n.²

Etymology: Shortened < either gobby n. or gobshite n.

Etymology: < gob n.³ Compare gab v.² In later use often associated with gob n.²; with to gob off compare to mouth off at mouth v. 3c.

Etymology: Apparently < gob n.¹ (although this is not attested in a corresponding specific sense). Compare earlier clog v. 5.The following may perhaps show much earlier use of a similar formation in a less specific sense:1583 B. Melbancke Philotimus (new ed.) sig. Qiii One Cornelius a stale hacking Courtier, who had long fed his fancie on Aureliaes well thewed shape, but hitherto had bare commons,..gubd Aurelia with golde to make his fare better, and backt Philotimus with rebukes.

Etymology: Either < gob n.⁴, or perhaps a back-formation < gobbing n.¹

Etymology: < gob n.¹; perhaps also sometimes associated with gob n.²Compare also earlier gob to gobble (rare; probably also < gob n.¹; compare sense 3 at that entry):1565 J.
