Etymology

From alteration of earlier bunny (“lump, swelling”), from Middle English bony, boni (“bunion, swelling”), perhaps Italian bubbone (augmented form of bugno (“beehive”)), or more likely from Lombard bugnon (“bunyon”), all three from Old French bugne, buigne, bune (“bump, knob, swelling”), from Old Norse bunga (“an elevation, bulge”) or Frankish *bungjō (“a swelling, lump, bump”), both from Proto-Germanic *bungô, *bunkô (“lump, clump, heap, crowd”), from Proto-Indo-European *bʰenǵʰ- (“thick, dense, fat”). Cognate with Dutch bonk (“lump, clump”), German Bunge (“swelling, tuber”).
