noun, masculine/so.vi.ɲɔ̃/plural: sauvignons
sauvignon (grape variety and wine)
Unknown, possibly related to servagnin (attested 1538, Lausanne) servagnin, sarvinien (1597), savagnin (Jura), regional names for types of grape. Possibly ultimately derived from the Gallo-Roman Latin name Salvinius (compare Salvinus, Salvinia, Salvius), before the velarization of the "-al" and with the substantive suffix -on.
