high-power

The compound adjective 'high-power' is a modern formation that transparently combines two native English words of ancient lineage. 'High' descends from the Proto-Germanic hauhaz, carrying the core sense of elevation, which was extended metaphorically to denote great degree or intensity. 'Power' traces back to the Latin verb posse (to be able), entering English via Anglo-Norman and embodying the concepts of capability, force, and authority. When combined, the literal sense of 'great power' logically applies to both the technical domain of electrical equipment and the social domain of influential individuals or actions, creating a clear and intuitive semantic link from its constituent parts to its modern definitions.

Structure: high (great) + power (energy/authority) - high: From Old English hēah, of Germanic origin; related to Dutch hoog and German hoch. Functions as an adjective meaning 'of great vertical extent' or, in a figurative sense, 'great in degree or intensity'. - power: From Anglo-Norman poer, Old French pouair, based on Latin posse 'be able'. Functions as a noun meaning 'the ability to do something' or 'energy or physical strength'.
