An Etymological Dictionary of the German Language/Annotated/Klotz

by Friedrich Kluge

Klotz, masculine and neuter, ‘block, log, stump,’ from Middle High German kloz (genitive klotzes), masculine and neuter, ‘lump, bullet,’ hence equivalent to Middle High German klôȥ; Anglo-Saxon *clott, English clot; we may therefore assume Gothic *klutta-, the relation of which to klauta-, mentioned under Kloß, is evident. In the non-Teutonic languages the Teutonic root klut (‘bale’?), adduced under Kloß, has not been definitely authenticated; a root glud appears in Lithuanian gludus, ‘clinging to,’ glausti, ‘to cling to.’
