Topology:Top-bottom

Writing Balance Rule: The top bamboo component must be compact and balanced horizontally, sheltering the bottom writing brush component without crushing it.
Simplification Logic: The traditional form 筆 combines 𥫗 (bamboo) and 聿 (hand holding a brush). The simplified form 笔 replaces the lower complex part with 毛 (hair/fur), creating a direct mnemonic combination of bamboo and hair.

Radical ⺮ · Bamboo Radical (bamboo)

Semantic Clue (形旁): 毛 (indicates the animal hair/fur used to make the brush tip)

A traditional writing brush is made of a bamboo stem (⺮) at the top and animal hair (毛) at the bottom.

  • ⺮ Bamboo stem at the top
  • 毛 Hair or bristles at the bottom
Liushu category: Phono-semantic (形声)

Origin: Originally depicted a hand holding a brush with animal bristles. Modern simplification cleverly combines 'bamboo' (⺮) on top and 'hair' (毛) on the bottom, representing the physical materials of a Chinese writing brush.

Semantic Evolution: Originally referred exclusively to the traditional ink brush, but over time expanded to include modern writing instruments like pens and pencils, as well as abstract concepts like brushstrokes and financial accounts.

  • The invention of the writing brush is traditionally attributed to General Meng Tian of the Qin dynasty.
