Morphology

unsmooth = smooth (transparent) = un + smooth

The meaning is a straightforward negation formed by the productive English prefix 'un-' plus the adjective 'smooth'.

Etymology

The word unsmooth is made from un- meaning 'not' and smooth meaning 'even' or 'soft'. So unsmooth simply means 'not smooth', something rough or bumpy, like hands after gardening.
