Etymology

Origin of mill1

First recorded before 950; Middle English noun miln(e), mille(n) “building for grinding grain,” Old English myl(e)n “(water) mill,” from Late Latin molīna, noun use of feminine of molīnus “of a mill,” equivalent to Latin mol(a) “mill” + -īnus -ine 1

Origin of mill2

An Americanism dating back to 1780–90; short for Latin millēsimus “thousandth”; see also mil 1

Explanation

A mill is a factory or plant, especially one that's equipped for grinding grain into flour. The facility is a mill, and the machine that does the actual grinding is also called a mill. When a mill crushes and grinds grain like wheat or corn, you can say it mills flour. Other kinds of mills might mill powder or coffee — and still other mills don't actually grind anything; instead, they manufacture things like steel or paper. If someone "mills around," they wander or move about in a confused way: "The crowd mills around during the concert's intermission." This sense of mill was originally used to describe cattle.
