Synonym discussion

Sense: noun/1

All these words refer to a part of something, but they differ in shape, size, and typical material. 'Piece' is the most general — any part of a whole, regardless of shape or size (a piece of cake, a piece of paper). 'Lump' suggests a roughly shaped, often soft or irregular mass (a lump of clay, a lump of coal). 'Hunk' is a large, thick piece cut or broken off something, often food (a hunk of bread, a hunk of meat). 'Slab' is wide, flat, and broad — like a rectangle (a slab of concrete, a slab of chocolate). 'Nugget' is small, naturally formed, and often valuable (a gold nugget, a chicken nugget). 'Chunk' sits between 'hunk' and 'lump': it is thick and irregular but implies the piece came from something larger by cutting or breaking. You would say 'a chunk of cheese' for a thick wedge, but 'a slab of cheese' for a flat, rectangular slice. For a random handful of soft material, 'lump' fits better than 'chunk.'

Etymology

Old FrenchEnglish

First recorded in English in the early 1600s, probably a variant of 'chuck' (a cut of beef from the shoulder, originally meaning a block of wood). 'Chuck' itself came from Old French 'chouque' or 'choque' meaning a log or block. By the 1800s, 'chunk' had expanded from physical lumps to abstract portions of time, money, or work.
