An Etymological Dictionary of the German Language/Stump
Stump, m., ‘stump,’ a LG. form for HG. Stumpf, MidHG. and OHG. stumpf. Corresponding to Du. stomp, E. stump (also OIc. stúfr, ‘stump’?). (ModHG. Stümper, ‘bungler, blunderer,’ lit. ‘mutilated person,’ is also properly LG.; comp. Du. stomper). - The adj. stumpf, ‘lopped, docked, blunt,’ comes from the equiv. OHG. and MidHG. stumpf; Du. stomp, ‘blunt.’ Its connection with Stummel is certain; besides the Teut. root stumb (Aryan stemp), in ModHG. Stummel, we have to assume an equiv. root stump (Aryan stemb), which appears in Lith. stambras, ‘stump.’ —
