Morphology

unburnable = burnable (transparent) = un + burn + able

Formed by prefixing un- to the adjective 'burnable' (burn + -able), producing the straightforward negation 'not able to be burned'.

Etymology

The word unburnable is made of un- 'not', burn 'to be on fire', and -able 'can'. So it literally means 'not able to burn', which is why we use it for materials that will not catch fire.
