hyperacusis

The term hyperacusis is a modern medical neologism constructed from classical Greek elements. It directly combines the prefix 'hyper-', denoting excess, with the root 'acusis', pertaining to hearing, and the nominal suffix '-is' indicating a pathological state. The logic is transparently literal: a condition (-is) of excessive (hyper-) hearing (acusis). While the ancient Greek akouein meant simply "to hear," its specialized medical derivative evolved to describe not enhanced ability but a debilitating hypersensitivity, illustrating how modern technical vocabulary repurposes ancient roots for precise clinical description.
