Morphology

uncorroborated = corroborated (transparent) = un + corroborate + ed

The adjective is formed by adding negative prefix 'un-' to 'corroborated', yielding the straightforward meaning 'not supported or confirmed'.

Etymology

Uncorroborated comes from corroborate, which means 'to make strong' and shares a root with robust, and the prefix un- means 'not'. So uncorroborated literally means 'not made strong' and describes a statement or evidence that is not supported by extra proof.
