An Etymological Dictionary of the German Language/Annotated/Schlund

by Friedrich Kluge

Schlund, masculine, ‘gullet, throat, chasm,’ from Middle High German and Old High German slunt, masculine, ‘gullet, throat, neck, abyss’; allied to Middle High German slinden, Modern High German schlingen (2), but with the preservation of the old dental, which schlingen has changed into a guttural.
