Morphology

unreactive = reactive (transparent) = un + react + ive

Formed by straightforward negation of the adjective 'reactive' with the productive prefix 'un-'.

Etymology

Unreactive comes from the parts un- 'not' and react 'to act back', the same root as reaction. So an unreactive person or response does not show a strong reaction or visible feeling.
