Usage
What does border mean? A border is the outer edge of a surface or image that marks its boundary in reference to others, such as a border you draw around a picture. A border is also a line that acts as a boundary between two or more geographic areas, whether it’s small areas, like between neighbors on the same street, or large areas, like between countries. To border often means to create a border, as on a picture. To border can also mean to form a border or to be next to one, as in Maine borders New Hampshire to the west and south and Canada to the north and east. Example: The border around the image is quite interesting, but I don’t think it fits the piece.

Etymology
Origin of border
First recorded in 1325–75; Middle English bordure, from Anglo-French, Old French, equivalent to bord(er) “to border” (derivative of bord “ship's side, edge,” from Germanic; see board) + -ure noun suffix; see -ure
Explanation
When you cross a border from one country into another, you'll need to show your identification papers and maybe a visa to the border patrol officials. A border separates one thing from another, most famously countries. Sometimes neighboring countries have border disputes, if they don't think the lines were drawn fairly or if they don't get along. Borders can also be less official. You might want to plant a border of cabbages along your front walk, or you could sew a border of sequins along the edge of your collar. But you'd have to go easy on the sequins, as too many would "border on the garish."
