Hard or soft rounded masses or bumps, especially ones that shouldn't be there or don't belong.
From Middle English and Middle Low German 'lump,' origin unknown but possibly related to Scandinavian words. The meaning has stayed consistent: a shapeless mass or bump.
The word 'lump' is great for describing things that don't fit categories—you have a 'lump sum' of money (all together), 'lump' gravy (chunky instead of smooth), lumps in your throat (emotion).
