The compound adjective 'wind-driven' is a transparent and relatively modern formation in English, built from two deeply rooted Germanic elements. The first element, 'wind,' descends from the Proto-Indo-European root h₂weh₁- meaning "to blow," which gave rise to terms for moving air across many languages. The second element, 'driven,' originates from the PIE root dhreibh- meaning "to drive, push." The compound's logic is perfectly literal: it describes something that is "propelled by the wind." This straightforward mechanical relationship is a direct inheritance of the core meanings of its constituent parts, applied to describe technologies like mills, pumps, or turbines that harness wind energy.

Structure: wind (air in motion) + driven (propelled) - wind: Old English origin, from Proto-Germanic windaz, meaning "air in motion." Functions as a noun used attributively to specify the source of power. - driven: Past participle of the verb 'drive,' from Old English drīfan, meaning "to propel, urge forward." Functions as an adjective-forming suffix indicating a state of being powered or compelled.
