Etymology: "Methaqualones" is simply the plural of "methaqualone," a sedative-hypnotic compound. The name is a compound built from pieces: "meth" (from methyl, a chemical group), "aqua" (from the quinazolinone ring, with its "aqua" element in the chemical naming scheme), "-al," and "-one," the last a suffix for ketones, which is the chemical class the molecule belongs to. Its name was assembled systematically in the manner of chemical nomenclature, so it reads as a label for a chemical structure rather than a word with a folk or literary history. Because the name encodes the molecule's composition, the plural simply refers to the family of closely related compounds sharing that core structure. The term describes a chemical family and carries no history beyond its construction from these parts.
