秋天
qiū tiān · HSK 2
autumn
🍂 秋天 = autumn (秋) + sky/day (天); literally autumn-sky.
秋 means autumn, and 天 means sky or day. Together 秋天 is the autumn season. The 天 suffix is the same pattern as 春天 (spring), 夏天 (summer), and 冬天 (winter).
天 — 一 (one/sky) above 大 (big person)
Originally a pictograph of a person (大) with an emphasized head, representing what is above — the sky or heavens. The top stroke evolved into 一, symbolizing the vast expanse overhead. From 'sky' it extended to mean 'day,' 'heaven,' and 'nature.'
