Millwright → It is formed from "mill" (from Old English *mylen*, meaning a building with machinery for grinding grain) and "wright" (from Old English *wyrhta*, meaning a worker or maker). A millwright is a worker who builds or repairs mills, particularly those that grind grain.
Think of a 'worker' ('wright') who builds or repairs a 'mill' — that's what a millwright does.
