Morphology

sunniness = sunny (semi-transparent) = sun + y + ness

The noun is formed from 'sunny' + '-ness' by a regular process, but 'sunny' in this sense is a metaphorical extension meaning 'cheerful', so the semantic link is figurative.

Etymology

Sunniness comes from sun meaning 'light and warmth' and the ending -ness meaning 'a quality'. So sunniness can also mean a warm, cheerful way of being—like a person who brings the brightness of the sun to others.
