Etymology 1

From Portuguese melaços or Spanish melazos, from Late Latin mellacium (“must, honey-sweet thing”), from mel (“honey”) + -āceus (“-aceous”) + -ium, q.v. Some alternative forms derived or influenced by Spanish melaza and French mélasse, conjectured to derive from unattested Late Latin mellacea, from mel + -ācea.
