Sunlit → It is formed from "sun" (from Old English *sunne*, meaning the star that provides light and warmth) and "lit" (the past participle of "light", meaning illuminated). The word "sunlit" describes something that is illuminated by the sun.
Think of the sun providing light — that's why sunlit means something that is lit up by the sun.
