Morphology

unsound = sound (semi-transparent) = un + sound

The prefix 'un-' negates 'sound', but the specific legal or mental health context is not immediately clear.

Etymology

Unsound is made of un- 'not' and sound 'healthy' or 'whole'. So a person of unsound mind is literally 'not healthy' in their mind, which is why the word means mentally ill or not legally sane.
