Etymology

Origin of demilitarize

First recorded in 1880–85; de- + militarize

Explanation

To demilitarize is to remove all armed forces from an area. When a country brings its troops home at the end of a war, they demilitarize the region. When a government removes its military forces, it demilitarizes the area those troops once occupied. This can happen because a conflict has ended, or for political or financial reasons. Removing military-grade weapons is also known as demilitarizing. If you retrofitted an old Army tank to be a food truck, you'd need to demilitarize it first. Demilitarize is made up of the prefix de-, or "not," and militarize, from the Latin militaris, "warlike."
