Morphology

hyperacute = acute (semi-transparent) = hyper + acute

The word is built transparently from hyper- + acute, but the medical sense of very rapid onset or reaction is somewhat specialized.

Etymology

Hyperacute is made of the parts hyper- ('over' or 'very') and acute ('sharp'). So a hyperacute medical problem is like something 'extra sharp': it starts very suddenly and is very strong, which is why it needs quick treatment.
