In England, a unit of distance, probably introduced by the Norman invaders and derived from the Gallic leuca. In the 12th – 13th centuries it was equal to 12 furlongs, not much bigger than the Gallic unit, but lengthened in the 14th century to 2 miles. From the 15th – 19th centuries it grew to = 3 (statute) miles, which is the present value in the United States and many other countries.
