救い
すくい · sukui · JLPT N1 · noun
aid
🛟 救 = 求 (seek) + 攵 (act): the act of answering a plea for help
救い is the noun form of the verb 救う (sukuu, to rescue), made by dropping the final u and using the stem. Both words share the kanji 救, so one kanji covers rescue, help, and 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'.
