The word "BISCAIS", which is pronounced as /bɪsˈkeɪz/, is a rare and archaic term that refers to a type of biscuit or cookie. Its spelling can be a bit tricky to understand, as it includes both a silent "c" and an "ai" combination that is pronounced as a long "a" sound. The origins of this word are uncertain, but it is believed to have been derived from either the French "bis cuit" meaning "twice-cooked" or the Spanish "bizcocho" meaning "sponge cake".
