A restaurant employee who orders and maintains the wines sold in the restaurant and usually has extensive knowledge about wine and food pairings.
From Old French, officer in charge of provisions, pack-animal driver, alteration of sommerier, beast of burden driver, from sommier, beast of burden.
Interesting, isn’t it?
Shining brightly; radiant.
Origin: 1500–10; < L refulgere to radiate light.
