A border is a line that separates two countries, regions, or areas. It can also mean an edge or decorative strip around something.
It comes from Old French “bordure,” from “bord,” meaning “edge” or “rim.” The idea of an edge expanded from physical objects to political and geographic boundaries.
From garden borders to national borders, we use the same word for decoration and division. That shows how humans love to mark edges, whether to make them beautiful, to control them, or both at once.
