Morphology

unsoundness = unsound (transparent) = un + sound + ness

The noun is a regular nominalization of the adjective 'unsound' (un- + sound), preserving the negative meaning.

Etymology

Unsoundness comes from the parts un- meaning 'not' and sound meaning 'healthy' or 'solid'. Think of an idea that is not 'solid'—its reasons have holes—so the unsoundness of an argument means it is not valid or reliable.
