Morphology

unprovable = provable (transparent) = un + prove + able

The adjective is formed by productive derivation ('prove' + '-able') and then negated regularly by 'un-', so the meaning 'not able to be proved' is directly inferable.

Etymology

The word unprovable is made of the prefix un- meaning 'not' and the verb prove, as in proof, meaning 'to show something is true', so unprovable means 'not able to be shown true' and describes ideas you cannot demonstrate.
