what is difference between clump and clustering



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). Cognates include Danish klump (probably from Low German as well). Compare Norwegian Bokmål klump.
