Spanish for "beer," from Latin cervisia "beer" (related to Latin cerea "a Spanish beer"), which is perhaps related to Latin cremor "thick broth," or from Celtic *kerb- (compare Gaulish curmi, Old Irish cuirm, Middle Irish coirm, Welsh cwrwf, Old Cornish coref "beer"), from Proto-Celtic *kormi-, probably from the same source as Latin cremare "to burn" (see cremation). "Connection with ceres (as a drink from grain) is very dubious" [Tucker].
