escargot (n.)

"edible snail," 1892, from French escargot, from Old French escargol "snail" (14c.), from Provençal escaragol, ultimately from Vulgar Latin *coculium, from classical Latin conchylium "edible shellfish, oyster" (see cockle (n.1)). The form of the word in Provençal and French seems to have been influenced by words related to scarab.
