[Middle English milne, mille, from Old English mylen, from Late Latin molīna, molīnum, from feminine and neuter of molīnus, of a mill, from Latin mola, millstone, from molere, to grind.]
REGIONAL NOTE To mill, in Western U.S. English, means "to run cattle in a circle, sometimes deliberately in order to halt a stampede." In the Oxford English Dictionary we find this 19th-century example of the verb: "At last the cattle ran with less energy, and it was presently easy to 'mill' them into a circle and to turn them where it seemed most desirable" (Munsey's Magazine). This usage of mill comes from the resemblance of the cattle's circular motion to the action of millstones. A related intransitive sense of the verb is better known in Standard English, as shown in the Oxford English Dictionary citation of an 1888 quotation from Theodore Roosevelt: "The cattle may begin to run, and then get 'milling'-that is, all crowd together into a mass like a ball, wherein they move round and round." Originally this sense of mill also meant "circular motion"; now it means "to move around in churning confusion" with no pattern in particular.
