high-voltage

The compound 'high-voltage' is a modern technical term formed within English by combining two pre-existing words. 'High' descends from the Proto-Germanic hauhaz, carrying the core sense of great height or degree. 'Voltage' originates from the surname of Alessandro Volta, inventor of the electric battery, with the suffix '-age' indicating a measurable quantity. Literally meaning "pertaining to a great electromotive force," the term's logic is transparent. Its figurative sense, meaning intensely exciting or dynamic, emerged through metaphorical extension, drawing a parallel between electrical intensity and emotional or energetic intensity.

Structure: high (great in vertical extent or intensity) + voltage (electrical force) high: From Old English hēah, of Germanic origin; related to Dutch hoog and German hoch. Functions as an adjective describing great magnitude or intensity. voltage: From the name of Alessandro Volta (Italian physicist) + the noun-forming suffix -age. The root 'volt' refers to the unit of electromotive force, and '-age' denotes a related state or measure.
