治療
ちりょう · chiryou · JLPT N3 · noun
treatment
💊🩺 治療 = cure + heal; chiryou sounds like cheer you back to health
治 means to govern or cure, as in 治る (naoru, to get better). 療 carries the sickness radical 疒, which marks illness kanji, and means to heal. Put together, cure + heal gives you medical treatment.
治 — water radical 氵 + 台 (phonetic)
治 originally referred to the name of a river, written with the water radical 氵 for meaning and 台 as the phonetic component. From 'managing rivers' (flood control), the meaning broadened to 'govern, regulate, manage,' and later 'cure, heal' — all senses of bringing something unruly under control.
