Radical 弓 · Bow Radical (bow (weapon))

Semantic Clue (形旁): 弓 (Represents the ancient bow binding or wrapping structure)

A bow (弓) wrapped with strings or vertical ties, symbolizing the junior sibling who assists and follows the older brother.

  • 弓 Bow radical representing shape and structure
  • 丨 Vertical piercing stroke representing the younger brother lined up behind
Liushu category: Pictogram (象形)

Origin: Originally depicted a wooden winding stick wrapped with rope or a measuring cord, later borrowed to mean younger brother due to junior ranking.

Semantic Evolution: Shifted from the physical act of winding or binding cordage to designate the junior male sibling in the family hierarchy.

  • In traditional Chinese kinship terms, birth order strictly dictates hierarchy, making 'dì' a foundational social concept.
