Morphology

insensitive = sensitive (transparent) = in + sens + itive

The prefix 'in-' straightforwardly negates 'sensitive', giving the meaning 'not sensitive' in the physical-response sense.

Etymology

Insensitive is made from in- meaning 'not' and sens- meaning 'feel', the same root as sense. So when something is physically insensitive, it does not 'feel' or react to touch, heat, or light.
