Etymology

Origin of mile

First recorded before 1000; Middle English; Old English mīl, from Latin mīlle (passus); mīlle, mīlia (passuum) “a thousand (paces), thousands of paces”

Explanation

A mile is a unit for measuring distance. There are 1,760 yards in a mile, which is the same as 5,280 feet or 63,360 inches. If you're exhausted in the morning, your mile-long walk to school might feel much longer. In the U.S. and the U.K., the mile is the standard unit for measuring roads and highways, while most other countries use the kilometer instead. You might hear people talk about how many miles per gallon their cars can go, or how many miles per hour they're allowed to drive. Informally, the word miles also means "a long way," or "a lot," so you might describe a crowd stretching for miles. The Latin root, milia, means "thousands."
