verdure (n.)youdaoicibaDictYouDict[verdure 词源字典]
late 14c., "fresh green color," from Old French verdure "greenness, greenery, green fields, herbs," from verd, variant of vert "green" (12c.), from Latin viridis (source of Spanish, Italian verde), related to virere "be green," of unknown origin. Perhaps ultimately from a root meaning "growing plant" and cognate with Lithuanian veisti "propagate," Old Norse visir "bud, sprout," Old English wise "sprout, stalk, etc." Meaning "green plants, vegetation" is attested from c. 1400.[verdure etymology, verdure origin, 英语词源]
