🔭 天 (sky) + 文 (writing/study) = study of the sky
天 means sky or heaven; 文 means writing, script, or a field of study. Together 天文 literally reads as sky-study, the classical Chinese term for astronomy.
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.'
文 — pictograph of crossed lines on a chest
文 originally depicted a person with patterns or tattoos drawn on the chest, shown as crossed or interwoven lines. From this image of decorative markings, it came to mean 'pattern,' then 'writing,' 'script,' and 'literature' or 'culture.' The modern senses all trace back to the idea of meaningful marks.
