An Etymological Dictionary of the German Language/Annotated/Schlupf

by Friedrich Kluge

Schlupf, masculine, ‘slip, refuge, pass, defile,’ from Middle High German slupf, ‘noose, cord,’ allied to Middle High German slüpfen, Middle High German and Old High German slupfen, Modern High German schlüpfen, ‘to slip,’ which is an intensive of Middle High German sliefen, ‘to slide, slip,’ corresponding to Gothic sliupan, ‘to slip’; Latin lûbricus seems to be primitively allied to it. —
