Etymology: Old English *wealde, Anglian *walde = Middle Low German walde (wolde), waude (still in Low German), Middle Dutch woude, wouwe (Dutch wouw; hence German wau, †waube, Swedish and Danish vau), possibly a derivative of wald, wood, forest. The Germanic word is the source of Spanish gualda, Portuguese gualde, French gaude. The later forms of the word show the same development of the vowel as the West Saxon weald weald n. and Anglian wald wold n.

a. The plant Reseda Luteola, which yields a yellow dye. Also, the dye obtained from this plant.
