mousseron

French

Etymology

Inherited from Middle French mouceron, from Old French moisserun, moisseron (compare Late Latin mussirio, Occitan mossalon, Catalan moixernó), of uncertain origin:

• Probably ultimately derived from Old French mosse, moise (“moss”), of Germanic origin, from Old Dutch *mos, from Frankish *mos, from Proto-Germanic *musą, as the type of fungus so-named applied to one which grows in moss.
• Klein and Watkins prefer a pre-Roman substrate origin, if the earlier form was something like Vulgar Latin *mussariōn.
