Morphology

untreated = treated (transparent) = un + treat + ed

Standard negation of 'treated' (as in wood or material processing), so the meaning 'not subjected to treatment' is directly inferable.

Etymology

Untreated comes from un- 'not' plus treat 'to change or protect something by a process'. So untreated means 'not changed or protected', which is why untreated wood or fabric stays in its original, natural state.
