🌤️ 天 = 大 (big) with a top stroke: the big open space above your head is the sky
Its classical form shows a big figure (大) with a line over the top: the great space above everyone. Read it as 'the big thing overhead' and you have heaven and sky.
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.'
