意味

Oath; pledge; alliance; covenant. A solemn binding agreement or commitment between parties, often between nations or organisations, carrying strong moral or legal force.

More formal and weighty than 約束 (promise) or 協定 (agreement), implying a sacred or inviolable commitment. Used in the contexts of military alliances, political coalitions, and historical treaties. The term conveys the idea that breaking the agreement would be a grave moral transgression, making it common in rhetoric about loyalty, betrayal, and international solidarity.
