Morphology

hyperreactive = reactive (transparent) = hyper + react + ive

The word is a straightforward combination of 'hyper-' meaning excessive and 'reactive' meaning responsive.

Etymology

Hyperreactive comes from the prefix hyper- meaning 'over' or 'too much' and the root react meaning 'to respond'. So a hyperreactive person or body responds much more strongly than normal to things like pollen, stress, or medicine.
