无足轻重
wú zú qīng zhòng · HSK 7
insignificant
🪶 无足轻重 = not (无) + enough (足) + weight (轻重, light-heavy); too light to tip the scale
无 — top 一 + 林-like middle + fire radical 灬 below
Originally a pictograph of a person dancing while holding ornaments or tassels, meaning 'to dance' — the ancestor of 舞. It was borrowed phonetically to write the negative 'not have / without,' and the dance meaning was reassigned to 舞 with an added foot element. The simplified form 无 comes from an ancient variant.
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.
轻 — vehicle radical 车 + 巠 (phonetic)
轻 is a semantic-phonetic compound. The left side 车 (vehicle) gives the meaning, originally referring to a light, swift chariot. The right side 巠 supplies the sound. Over time the meaning broadened from 'light cart' to 'light in weight' and figuratively 'slight' or 'gentle'.
重 — person 人 + east 東 (phonetic)
Originally depicted a person carrying a heavy bundle on their back, suggesting weight and burden. The 東-like element served as a phonetic component. Over time the character split into two readings: zhòng meaning 'heavy' and chóng meaning 'repeat/again'.
