Morphology

unreinforced = reinforced (transparent) = un + reinforce + ed

The meaning is directly 'not reinforced' by productive negation 'un-' applied to the clear adjective 'reinforced'.

Etymology

Unreinforced starts with un- meaning 'not' and the rest is reinforce, which is re- 'again' plus force 'strength'. So unreinforced means 'not made stronger', as in a wall or bridge without extra support.
