Etymology: "Hyperinnervations" is the plural of "hyperinnervation", a noun formed from the prefix hyper- ("over, beyond, excessively") attached to "innervation". Innervation itself comes from the Latin "innervare", meaning to supply with nerves, built from "in-" ("into") and "nervus" ("sinew, nerve"). In physiology, innervation refers to the way nerves supply a body part, so the compound describes a supply of nerves that has become excessive. The prefix hyper- is a Greek element meaning "above" or "over", and in English it is a productive combining form that attaches to many nouns to mean "too much of" that thing. The word therefore needs no special history of its own; it is a transparent formation, and its meaning follows directly from its two parts.
