Meanings

  • behavior as a consistent pattern or disposition over time
  • military, organizational, or collective action such as campaigns or operations

Etymology

Phonology: 行動 is a Sino-Japanese compound formed from two kanji whose on’yomi readings combine to yield the pronunciation koudou; it is written in kanji with Chinese-derived readings rather than native kana.

Origin

Adopted from Chinese writing; earliest attestations occur in classical Japanese texts using kanbun; became common in the Heian period and widely used in modern Japanese.

Composition

  • 行: to go, to act; movement or action as a concept
  • 動: movement, motion; implies activeness

Usage

Used primarily as a noun to label action or conduct; in formal contexts it describes observable or intentional acts; in psychology and social sciences it denotes behavioral patterns; in everyday speech it refers to a person’s actions in a given situation.
💡 Tips
Mnemonic: imagine stepping along a line (行) and then generating motion (動) to take a step — that is action.

Variations

  • 行為 (koui) — behavior or act
  • 振る舞い (furumai) — conduct
  • 動作 (dousa) — movement
