prevent and cure
🛡️💊 防 = prevent/guard + 治 = cure/govern → prevent and cure
防 carries the sense of guarding against (as in 防止 'prevent'), and 治 means to treat or manage (as in 治疗 'treat'). Together: the paired work of prevention plus treatment, common in public-health contexts.
防 — mound radical 阝(阜) + 方 fāng (phonetic)
防 is a semantic-phonetic compound. The left element 阝 (from 阜) depicts a mound or earthen embankment, suggesting barriers and defense. The right element 方 supplies the sound. Together they evoke a dike or rampart that guards against floods or attacks, hence 'to guard, prevent, defend'.
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.
