What does clumped mean?
'Clumped' is the past tense and past participle of the verb 'to clump', meaning to form or gather into a thick, dense mass or cluster. It most often describes physical substances — flour, soil, wet hair, or snow — that have stuck together into lumps, especially after getting damp or compressed. It can also describe people or animals moving or standing close together in a group, as when pedestrians clump around a street performer. The word carries a slightly informal, concrete register and often implies heaviness or untidiness: things that clump are usually harder to separate or spread out again. Derived from the noun 'clump', a compact mass or thicket, it belongs to an old Germanic family of words relating to blunt, heavy masses. Its adjective use ('clumped grass', 'a clumped arrangement') describes anything growing or placed in dense tufts rather than evenly spaced.
