borders

Lines between nations

Borders are boundary lines separating territories—countries, states, or regions: The river forms the border between the two nations.

The verb means to share such a boundary: Mexico borders the United States.

Something that borders on a quality approaches it: His confidence borders on arrogance.

A border can also be a decorative edge or frame: a floral border on the tablecloth.
