An Etymological Dictionary of the German Language/Salweide
Salweide, f., ‘sallow, round-leaved willow’; allied to MidHG. salhe, f., OHG. salaha (Goth. *salhô), f., ‘willow’; the second part of the ModHG. compound serves as. an explanation of the old term, which is undoubtedly of genuine Teut. origin; comp. OIc. selja, f. (Goth. *salhjô), and AS. sealh, E. sallow. Primit. allied to Gr. ἑλίκῇ (Arcad.), Lat. sălix (acc. salicem), ‘willow’; Fr. saule is based not on the Lat., but on the HG. word.
