Etymology

Origin of lump¹

First recorded in 1300–50; Middle English lumpe, lomp(e); cognate with early Dutch lompe “piece,” Danish lump(e) “lump,” dialectal Norwegian lump “block”

Origin of lump²

An Americanism dating back to 1785–95; perhaps identical with British dialect lump “to look sullen”

Explanation

If it's hard to determine its shape and otherwise looks like a big blob of something, it's probably safe to call it a lump. Jabba the Hut looks like a disgusting lump. So does the growing mound on your noggin where you walked into the glass door. And if you've been lumped together with a bad bunch, you might have been grouped with people indiscriminately. But all lumps aren't bad. Little old ladies put lumps of sugar into their tea. And that choked up feeling you get during a sappy movie? That's just a lump in your throat.
