Morphology

unsharpness = unsharp (transparent) = un + sharp + ness

Formed by the productive negating prefix 'un-' on 'sharp' and the noun-forming suffix '-ness', so the meaning is directly predictable from the components.

Etymology

Unsharpness is easy to remember: it is made of un- meaning 'not', sharp meaning 'clear', and -ness meaning 'the quality of'. So unsharpness is the 'quality of not being clear', like a blurry photo or a fuzzy idea.
