足够
zúgòu · HSK 3
enough
👣 足 = foot + 够 = enough; together: enough to stand on
足 means foot/sufficient and 够 means enough — both characters carry the sense of sufficiency, doubling up for emphasis. Sound zúgòu rhymes with zoo-go, a steady stomping cadence meaning amply, fully, enough.
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.
够 — 句 (phonetic) + 多 (semantic 'much')
够 is a semantic-phonetic compound. 多 ('many, much') gives the meaning of sufficiency or abundance, while 句 (gōu/jù) supplies the sound. Originally written 夠 with the same parts reversed, it came to mean 'enough' or 'sufficient' in modern usage.
