"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."
"voracious, savage," late 14c., present-participle adjective from an extinct verb ravine, raven "to prey, to plunder, devour greedily" (mid-14c.), from Old French raviner, ravinier "to seize, pillage" (see raven (v.)). It is etymologically related to ravenous, but not to raven (n.). Related: Raveningly.
"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").
