A clod of earth or a lump of soil. Measure word for chunks and pieces; colloquial term for a yuan (money). Earth (土) split by a crack (夬) into a solid broken-off lump.

Don't Confuse 块 (kuài) with 快 (kuài)

Same sound, different meaning: money vs. speed

They sound identical, but 块 is about chunks and cash, while 快 is about speed. The trick is in the radical.

Key Contrast: vs. (kuài)

块 has the earth radical (土) on the left, hinting at dirt and lumps. 快 has the heart radical (忄) on the left, linking to quickness and emotion.

Memory Hook

Think of a lump of earth (块) sitting still, while a fast runner (快) has a heart pounding.

The Character's Secret: Earth Split by a Crack

See the lump in the character and never forget it

块 is made of 土 (earth) on the left and 夬 (guài) on the right, which suggests a split. The image: a solid clod of earth broken off.

The left radical 土 means 'earth' or 'soil'. The right part 夬 originally depicted a crack or a decision, but here it hints at something split off. Together, they form the idea of a lump of earth – a chunk. This visual of a broken-off clod is the core meaning that extends to pieces and money.
