(たいぎ)

たいぎ
noun

A moral or ethical principle that justifies an action, especially one involving sacrifice or conflict. Often used in political, military, and historical contexts to describe the higher purpose behind an action.

USAGE:
Often appears in the four-character compound 大義(たいぎ)名分(めいぶん) (just cause, moral justification). This compound is especially common and means the publicly stated reason or moral justification for an action. Without 大義(たいぎ)名分(めいぶん), an action is seen as lacking legitimacy.

COMMON COLLOCATIONS:

  • 大義(たいぎ)名分(めいぶん): just cause, moral justification
  • 大義(たいぎ)のために: for the sake of a just cause
  • 大義(たいぎ)(かか)げる: to champion a cause
  • 大義(たいぎ)(うしな)う: to lose one's moral justification

HISTORICAL NOTE:
In Japanese history, 大義(たいぎ)名分(めいぶん) was a key Confucian concept used to justify political actions, including the overthrow of the shogunate during the Meiji Restoration.
