Word Origin and History for nomenclatural
nomenclature
1610, "a name," from Fr. nomenclature, from L. nomenclatura "calling of names," from nomenclator "namer," from nomen "name" + calator "caller, crier," from calare "call out" (see calendar). Nomenclator in Rome was the title of a steward whose job was to announce visitors, and also of a prompter who helped a stumping politician recall names and pet causes of his constituents. Meaning "list or catalogue of names" first attested 1635; that of "system of naming" is from 1664; sense of "terminology of a science" is from 1789.
