verdigris: [14] Etymologically, verdigris means ‘green of Greece’. It comes from Old French vertegrez, a conflation of vert de Grece ‘green of Greece’ (vert came from Latin viridis ‘green’, which also gave English verdant [16] and verdure [14] and may be related to Old English wīse ‘sprout, stalk’, Old Norse vísir ‘bud, sprout’, and Lithuanian veisti ‘propagate’). The reason for the application of the term to the patina on copper is not known.
