Etymology: Long before wind turbines, the windmill was a Middle English compound built from two plain parts: "wind" and "mill," the latter ultimately tracing back to Latin "molere," meaning "to grind." The "mill" element entered the language much earlier than the first half, arriving through Old English "mylen" and Late Latin "molīnus," so the word is essentially a pairing of a native English word for moving air with a grinding machine borrowed centuries before. The compound took its shape in Middle English as "wyndmylne" and "wyndmylle," and its cognates are spread across the Germanic languages, from Dutch "windmolen" to German "Windmühle" and Swedish "vindmölla," showing that the idea of a wind-driven grinder was shared widely among Germanic-speaking peoples. The word also carries a literary echo. Its figurative sense of an imagined enemy comes from Cervantes's Don Quixote, who tilts at windmills he takes to be giants.
