vetch (n.) Look up vetch at Dictionary.com
climbing herb, late 14c., from Old North French veche, variant of Old French vece, from Latin vicia "vetch," which perhaps is related to vincire "to bind" (compare second element of periwinkle (n.1)), or from PIE root *weik- (2) "to bend, to wind." Dutch wikke, German Wicke are loan-words from Latin vicia.
