Etymology

From Middle English clompe, from Old English clymppe, a variant of clympre (“a lump or mass of metal”), from Proto-Germanic klumpô (“mass, lump, clump; clasp”), from Proto-Indo-European glembʰ- (“lump, clamp”). Alternatively, possibly from Middle Dutch clompe or Middle Low German klumpe (compare German Klumpen). Doublet of klomp. Cognates include Danish klump (probably from Low German as well). Compare Norwegian Bokmål klump.
