Etymology

Origin of ranger

Middle English word dating back to 1350–1400; see origin at range, -er ¹

Explanation

A ranger is a person who takes care of a park or a piece of land. A park ranger makes sure the rules are followed and provides information to visitors. Someone who takes a job as a forest ranger might patrol an area of wooded land, watching for fire danger and enforcing the rules. A ranger's tasks can vary from teaching kids about local plants and animals to fighting fires to arresting people who break laws in a state or national park. The original rangers were British employees of the king or queen who would "range" throughout the woods looking for poachers — people who illegally hunted on royal land.
