Surface Forms

unsolvable positive

Morphology

unsolvable = solvable (transparent) = un + solve + able

Formed by adding the productive negative prefix 'un-' to the adjective 'solvable', yielding the straightforward opposite meaning.

Etymology

Unsolvable has un- meaning 'not' and solve from an old word meaning 'to loosen', the same idea you see in solution and dissolve. So an unsolvable problem is like a knot you cannot loosen — it is impossible to work out.
