Definition

Noun: A DMZ (Demilitarized Zone) is a specifically defined area, often a border strip, where military forces, weapons, fortifications, and military activities are forbidden by international agreement. Its primary purpose is to create a buffer and reduce the risk of armed conflict between opposing sides.

Usage

The term "DMZ" is almost always used as a proper noun, often preceded by "the," to refer to a specific, well-known demilitarized zone. It is a standard term in geopolitics, military discourse, and historical contexts. * The most famous example is the DMZ between North and South Korea. * The agreement established a DMZ along the contested border. * Wildlife has thrived in the DMZ due to the absence of human activity.

Advanced Usage
