hump

Probably borrowed from Dutch homp (“hump, lump”) or Middle Low German hump (“heap, hill, stump”), from Old Saxon *hump (“hill, heap, thick piece”), from Proto-Germanic *humpaz (“hip, height”), from Proto-Indo-European *kumb- (“curved”). Compare Proto-Germanic *huppōną (“to hop”), from Proto-Indo-European *kewb-, *ḱewb- (unnasalised root), and English hub (a softened variant without nasal?).

Cognate with West Frisian hompe (“lump, chunk”), Icelandic huppur (“flank”), Welsh cwm (“a hollow”), Latin incumbō (“to lie down”), Albanian sumbull (“round button, bud”), Ancient Greek κύμβη (kúmbē, “bowl”), Avestan 𐬑𐬎𐬨𐬠𐬀 (xumba, “pot”), Sanskrit कुम्ब (kúmba, “thick end of bone”). Replaced, and perhaps influenced by, Old English crump (“crooked, bent”). More at cramp.
