"passage from the mouth of an animal to the stomach," c. 1300 (as a surname), from Old French golet "neck (of a bottle); gutter; bay, creek," diminutive of gole "throat, neck" (Modern French gueule), from Latin gula "throat," also "appetite," which is related to gluttire "to gulp down, devour," glutto "a glutton." De Vaan writes, "We seem to be dealing with an onomatopoeic formation of the form *gul- / *glu-." Compare Old English ceole "throat;" Old Church Slavonic glutu "gullet," Russian glot "draught, gulp;" Old Irish gelim "I devour."
"greediness of appetite, voraciousness," 1520s, from French voracité (14c.) or directly from Latin voracitatem (nominative voracitas) "greediness, ravenousness," from vorax (genitive voracis) "greedy, ravenous, consuming," from vorare "to devour," from PIE *gwor-a-, from root *gwora- "food, devouring."
1907, glahm "grab, snatch, steal," American English underworld slang, from Scottish glaum (1715), apparently from Gaelic glam "to handle awkwardly, grab voraciously, devour." Sense of "look at, watch" (1945) apparently is derived from the same source. Related: Glommed; glomming.
"eating or feeding on flesh," 1640s, from Latin carnivorus "flesh-eating, feeding on flesh," from caro (genitive carnis) "flesh" (originally "a piece of flesh," from PIE root *sker- (1) "to cut") + vorare "to devour" (from PIE root *gwora- "food, devouring"). Related: Carnivorously; carnivorousness; carnivoracity.
"putrefaction or necrosis of soft tissues," 1540s, cancrena, from Latin gangraena (Medieval Latin cancrena), from medical Greek gangraina "an eating or gnawing sore," literally "that which eats away," a dissimilated, reduplicated form of gran- "to gnaw," from PIE root *gras- "to devour" (see gastric).
"condition or quality of being corpulent," 1610s, from French obésité and directly from Latin obesitas "fatness, corpulence," from obesus "that has eaten itself fat," past participle of obedere "to eat all over, devour," from ob "about; because of" (see ob-) + edere "eat" (from PIE root *ed- "to eat").
