Pronunciation

Forms

gui m (plural guis)[1] Old and Middle French visc, vist and viz (late 14th century), then guy and guix.[2][3][4]

Etymology

The word for mistletoe is inherited from Middle French guy, inherited from Latin viscum (“mistletoe, birdlime”),[2][5][6][3] like Old Occitan vesc (12th–14th centuries).[2][6] The forms with /i/ (visc, vist, viz) are probably due to the influence of the descendants of hibiscus (compare guimauve).[2][6] The initial ⟨g⟩ for ⟨v⟩ is put down to Frankish *wīhsila (“wild cherry”), whose fruit looks somewhat like the mistletoe berry (compare guigne).[2][6][3][1] Bloch and Wartburg add that the Latin and the Frankish word go back to the same Indo-European root;[3] Rey suggests that the Latin word may be related to Ancient Greek ἰξός (ixós, “birdlime”).[6]

Cognate with Italian vischio and Italian visco.[4]

Earliest recorded meaning

Guy de chesne “oak mistletoe” is found in 1372 in an account of the will of Queen Jeanne d'Évreux; a guy with two silver rings in a text of 1347 may be the same word, but its sense is doubtful.[2][6][7]

Semantic evolution

Besides the plant, the word carries the symbolism of the New Year, in the cry au gui l'an neuf, and calls up the religious customs of ancient Gaul and its druids, a theme taken up by Chateaubriand and the Romantics.[6][4] Its berries were used to make a glu of lower quality than that made from holly bark.[4]
