An Etymological Dictionary of the German Language/Annotated/hüten

by Friedrich Kluge

hüten, verb, ‘to heed, take care,’ from Middle High German hüeten, Old High German huoten, ‘to watch, take care’; Gothic hôdjan is wanting, Anglo-Saxon hêdan, English to heed (also as a substantive), Dutch hoeden, Old Saxon hôdian. Teutonic root hôd, from the Aryan kā̆dh (kō̆dh?) or kā̆t; perhaps allied to Latin cassis (for *cat-is), ‘helmet,’ also to Middle High German huot, ‘helmet,’ English hat. See Hut (1).
