救済
きゅうさい · kyuusai · JLPT N1 · noun
aid
🛟 救 = rescue + 済 = settled, done: a rescue that leaves you relieved
救 means save or rescue, and 済 means finish or be settled. Together they describe being saved from trouble, which brings relief.
救 — 求 (seek/phonetic) + 攵 (strike/action)
A semantic-phonetic compound. The right side 攵 (a hand holding a stick) gives the action sense of intervening or stopping, while 求 supplies the sound 'jiu'. Originally meaning to halt or stop something bad, it extended to 'rescue, save, aid'.
