Etymology

Origin of zone

First recorded in 1490–1500; from Latin zōna, from Greek zṓnē “belt”

Explanation

A zone is an area that has some special characteristic, like a loading zone. "The Twilight Zone" was a TV show where odd things happened. Similarly, any zone is a place that has some special feature. A loading zone is a spot where cars and trucks can unload things and people. A military zone is a place under control of the armed forces. To create a zone is called zoning: zoning breaks something into parts or sections. An election board zones an area into separate zones such as districts.
