köken: From Middle French pluvieux, from Old French pluviex (13th c.), from Latin pluviōsus. The regular descendant of this is Old French plujos, which would have yielded modern *plugeux; compare Catalan plujós. By analogy with pluie, there was also a byform pluios (Middle French pluyeux), in which /v/ may have been inserted after plovoir; compare the Middle French variants plouvieux, pleuvieux.…
köken: From ploaie (“rain”) + -os (“-ous”); possibly corresponds to Latin pluviōsus. Compare Aromanian pluios, Italian piovoso, Friulian ploiôs, Catalan plujós, French pluvieux.
