Part of speech: noun

Definitions

3. A situation where sensory signals are amplified beyond normal limits, potentially resulting in agitation or discomfort

Etymology: The word is a plain compound: the prefix hyper- joined to stimulation. Hyper- comes from ancient Greek "hupér", meaning "over" or "beyond", which also gave English words like hyperactive and hypertension. Stimulation, in turn, comes from the Latin "stimulare", "to goad", from "stimulus", a sharp pointed stick used to prod oxen. Put together, the word describes stimulation pushed past its normal bounds, a prodding that has gone beyond what the nervous system can comfortably take. Nothing about its formation is unusual. The English pieces were already in place, and the combination is a straightforward modern coinage built from classical parts, so the interest lies mainly in the original image of the goad. Stimulation began as a literal prod before it came to mean a stirring of the senses or mind.
