治病
zhì bìng · HSK 6
to treat an illness
💊 control + sickness — 治 means govern, 病 means illness, so govern the disease away
治 originally meant to tame floods and keep rivers in check. It extended to taming illness. Pair it with 病 (sick) and you get the act of bringing a disease under control.
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.
病 — sickness radical 疒 + 丙 (bǐng, phonetic)
病 is a semantic-phonetic compound. The radical 疒 depicts a person lying on a bed and signals illness or ailment. The component 丙 supplies the sound (bǐng → bìng). Originally 病 referred to a serious illness, contrasted with 疾 for a lighter ailment; today it broadly means 'sick' or 'disease.'
