知足
zhī zú · HSK 7
content with one's situation
😌 知足 = know (知) + foot/enough (足): to know you have enough
足 means both foot and enough/sufficient; paired with 知 to know, 知足 is knowing what is enough. The proverb 知足常乐 says one who knows contentment is always happy.
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.
