A miller is a person who operates a mill, a machine to grind a grain (for example corn or wheat) to make flour. Milling is one of the oldest of human occupations. "Miller", "Milne" and other variants are common surnames, as are their equivalents in other languages around the world ("Melnyk" in Russian, Belarusian & Ukrainian, "Meunier" in French, "Müller" or "Mueller" in German, "Mulder" and "Molenaar" in Dutch, "Molnár" in Hungarian, "Molinero" and "Molina" in Spanish, "Molinaro" or "Molinari" in Italian, "Mlinar" in South Slavic languages etc.). Milling existed in hunter-gatherer communities

It may resemble a water wheel in appearance, and can be worked either by a human treading paddles set into its circumference (treadmill), or by a human or animal standing inside it (treadwheel). These devices are no longer used for power or punishment, and the term "treadmill" has come to mean an exercise machine for running, walking or other exercises in place.
