What is the origin of mellifluous?

Mellifluous comes from Late Latin mellifluus “flowing with honey, (of a taste or scent) sweetened with or as if with honey,” and by extension “eloquent, persuasive.” Mellifluus is a compound of mel (inflectional stem mell-) “honey” and –fluus “flowing,” a derivative of fluere “to flow.” Mel is the Latin result of the Proto-Indo-European melit “honey,” which in Greek appears as méli (inflectional stem mélit-). Melit– corresponds exactly with Hittite milit (from melit), Old Irish mil (also from melit). In the Germanic languages, an expanded form, melitom, yields Gothic milith “honey,” Old English mildēaw, meledēaw “honey dew, nectar” (in English, the mil– of mildew, which was thought to be distilled or condensed from air like dew). Mellifluous entered English in the 14th century.
