early 13c., from Old French gluton (Modern French glouton), from Latin gluttonem (nominative glutto) "overeater," formed from gluttire "to swallow," from gula "throat," from PIE *gwele- (see glut (v.)).
(Deut. 21:20), Heb. zolel, from a word meaning "to shake out," "to squander;" and hence one who is prodigal, who wastes his means by indulgence. In Prov. 23:21, the word means debauchees or wasters of their own body. In Prov. 28:7, the word (pl.) is rendered Authorized Version "riotous men;" Revised Version, "gluttonous." Matt. 11:19, Luke 7:34, Greek phagos, given to eating, gluttonous.
