Etymology

From Middle English bunne (“wheat cake, bun”), from Anglo-Norman bugne (“bump on the head; fritter”), from Old French bugne (hence French beignet), from Frankish bungjo (“little clump”), diminutive of bungu (“lump, clump”), from Proto-Germanic bungô, bunkô (“clump, lump, heap, crowd”), from Proto-Indo-European *bʰenǵʰ- (“thick, dense, fat”). Cognate with Dutch bonk (“clump, clot, cluster of fruits”). More at bunch.

Probably from Scots bun (“tail of a rabbit or hare”), which is probably from Scottish Gaelic bun (“bottom, butt, stump, stub”).

Caribbean pronunciation of burn.

From the Revised Romanization of Korean 분 (bun), from Chinese 分 (fèn, “fen”). Doublet of fen.
