An Etymological Dictionary of the German Language/Annotated/Wand
Wand, feminine, ‘wall, partition’, from Middle High German want (d), Old High German want, feminine, ‘wall, side’; compare Old Saxon and Dutch wand. This word is wanting in the other dialects (compare Gothic waddjus, English wall). To connect it with the phonetically related winden gives no sense; Wand, literally ‘turning’?.
