节气
jié qi · HSK 7
solar term
🌱🌾 节 = segment/node + 气 = air/weather: the year cut into weather-nodes
节 — bamboo radical 竹 (⺮) + 即
Originally written 節, depicting a bamboo joint — the segmented node where a stalk divides. The bamboo radical ⺮ gives the meaning, while 即 supplies the sound. From 'bamboo joint' the meaning expanded to any segment, hence 'section,' 'festival' (a marked point in the year), and 'restraint' (knowing where to stop).
气 — steam/vapor radical 气
Originally a pictograph of rising vapor or clouds drifting in the sky, depicting curling streams of air. The character came to mean breath, air, and by extension vital energy or 'qi.' The simplified form 气 keeps the original outline; the traditional 氣 added 米 (rice) to suggest steam rising from cooking grain.
