low-voltage

The compound 'low-voltage' is a modern technical term from electrical engineering. Its first element, 'low', is a fundamental Germanic adjective from Old English, ultimately from a Proto-Indo-European root meaning 'to lean' or 'to be flat', conveying the sense of reduced height or degree. The second element, 'voltage', entered English in the late 19th century, derived from the name of Italian physicist Alessandro Volta, inventor of the voltaic pile, combined with the suffix '-age' denoting a measurable quantity. The logic of the compound is transparently descriptive: it literally denotes an electrical system or device characterized by a 'low' measure of electrical potential (voltage), as opposed to a high-voltage one, with the combined meaning solidifying into a standard technical adjective.

Structure: low (small in amount/degree) + voltage (electrical force) low: From Old English 'hlāw', 'hlēow' (not high, humble). In this compound, it functions as an adjective meaning 'small in amount, degree, or intensity'. voltage: A noun formed from 'volt' (unit of electrical potential, named after Alessandro Volta) + the noun-forming suffix '-age' (indicating a related measure or aggregate).
