An Etymological Dictionary of the German Language/Annotated/Schraube

by Friedrich Kluge

Schraube, feminine, ‘screw,’ from the equivalent late Middle High German schrûbe, feminine; allied to Dutch schroef (English screw), Icelandic skrúfa; these terms, some of which may have been borrowed, and hence do not correspond exactly in sound, are essentially Modern Teutonic. Note Suabian schrauf, Bavarian schraufen (compared with Swiss štrûbe). Origin obscure.
