急救
jíjiù · HSK 6
first aid
🚑 jí jiù = urgent + rescue — rush to save someone
急 means urgent or hurried, 救 means to rescue or save. Together they form first aid: the urgent rescue you give before the ambulance arrives.
急 — heart radical 心 + 及 (reach)
A semantic-phonetic compound: the heart radical 心 supplies the meaning (an emotional state) while 及 ('to reach, catch up') gives the sound. Originally it depicted a racing, anxious heart — hence the modern senses 'urgent,' 'hurried,' and 'impatient.'
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'.
