Etymology: "Hyperreaction" is a plain compound: the prefix "hyper-", from Greek "huper" meaning "over" or "beyond", attached to "reaction", which comes from Latin "reactio" (from "reagere", "to act back"). Put together, the word means a response that goes beyond the expected or appropriate degree. The prefix "hyper-" is a productive one in English, and it is attached freely to nouns to mark excess, as in "hypersensitivity" or "hyperactivity". "Hyperreaction" follows this pattern, pairing the Greek-derived prefix with a much older Latin-derived base word, which is typical of technical and medical English in general.

Synonyms: overreaction, exaggeration
