An Etymological Dictionary of the German Language/Waid

by Friedrich Kluge

Waid, m., ‘woad, blue dye,’ from the equiv. MidHG. and OHG. weit, m.; corresponding to the equiv. Du. weede, AS. wâd, E. woad, Goth. *waida- (for which wizdila, ‘woad,’ is found,’ whence MidLat. guasdium, Fr. guède). From Teut. is derived the equiv. Rom. cognate, Ital. guado. Lat. vitrum, ‘woad,’ is historically related to the Teut. cognates, which may be based on pre-Teut. waitó.
