gourmet (n.)

c. 1200 (late 12c. in surnames), grome "male child, boy;" c. 1300, "a youth, young man," also "male servant, attendant, minor officer in a royal or noble household ranking higher than a page; a knight's squire." A word of unknown origin with no certain cognates in other Germanic languages.

Perhaps it is from an unrecorded Old English *grom, *groma, which could be related to growan "to grow," and influenced by guma "man." Or perhaps it is from or influenced by Old French grommet "boy, young man in service, serving-man" (compare Middle English gromet "ship's boy," early 13c.). As the title of an officer of the English royal house from mid-15c. The specific meaning "male servant who attends to horses and stables" is from 1660s, from earlier combinations such as horse-groom, Groom of the Stables, etc.

late 15c., gourmaunt, "glutton," from Old French gormant "glutton," originally an adjective, "gluttonous," a word of uncertain origin. Not considered to be connected with gourmet. Meaning "one fond of good eating" is from 1758.

The gourmand is one whose chief pleasure is eating; but a gourmet is a connoisseur of food and wines. In England the difference is this: a gourmand regards quantity more than quality, a gourmet quality more than quantity. [Brewer, "Dictionary of Phrase and Fable," Philadelphia, 1898]
