plump
adjectiveFull; swelled with fat or flesh to the full size; fat; having a full skin; round; as a plump boy; a plump habit of body. The famish’d crow grows plump and round.
[This word is not now used in this sense, but the use of it formerly, is good evidence that plump is clump, with a different prefix, and both are radically one word with lump. Plumb, L. plumbum, is the same word, a lump or mass.]
