Morphology

mental + unsoundness

The phrase straightforwardly combines 'mental' (relating to the mind) with 'unsoundness' (a lack of soundness or impairment), so the meaning 'impaired mental state' is directly derivable from the parts. This follows a standard adjective + noun compositional pattern found across languages, so a B1 learner who knows both constituents would readily infer the meaning.

Etymology

Mental unsoundness comes from the old use of unsound, which described things that were 'not solid' or 'not safe'—like a weak bridge that might fall. When people put unsound with mental, it creates an image of a mind that is not steady or safe. That's why mental unsoundness means being mentally disturbed and unable to think or act normally.
