充足
chōngzú · HSK 5
ample
🍱 充 fill + 足 foot/enough = fully sufficient, ample
充 means to fill or stuff, 足 means foot but also enough/sufficient. Together they form a compound meaning fully adequate or plentiful — when supply has been filled to the level of being enough.
充 — 育 (raise/grow) on top of 儿 (legs/person)
Originally depicted a person walking forward, suggesting movement and advancement. The form combines a growth element above with a person below, evoking the sense of being filled up or made full as one grows. Over time, the meaning shifted from 'go forward' to 'fill, fulfill, abundant'.
足 — top 口 (mouth/enclosure) + bottom 止 (foot)
Originally a pictograph of a leg and foot, with the upper square representing the knee or shin and the lower part 止 depicting the foot itself. It primarily means 'foot' and by extension 'sufficient' or 'enough,' a meaning shift likely from the idea of standing firmly or having a solid footing.
