Origin: 1575–85; earlier molassos, molasso(e)s < Portuguesemelaços, plural of melaço (< Late Latinmellācium half-boiled new wine, for *mellāceum, neuter of *mellāceus honeylike, equivalent to mell-, stem of mel honey + -āceus-aceous)
1582, from Port. melaço, from L.L. mellaceum "new wine," properly the neut. of mellaceus "resembling honey," from L. mel (gen. mellis) "honey." Adopted in Eng. in plural form, but regarded as a singular noun.
