interregional

The word interregional describes connections, interactions, or movement that happen between different regions. It is often used in geography, economics, politics, and similar fields to show relationships that go beyond a single area. Think of it as a way to describe links between places that are separate, but not isolated from one another.

For example, an interregional highway system is not just a road within one area; it connects multiple regions and supports travel and trade between them. In the same way, interregional migration means people moving from one region to another, such as from one part of a country to a very different one.

In economics, interregional trade means the exchange of goods and services between regions. In politics, an interregional organization may bring together states, provinces, or countries to deal with issues that affect more than one area. The word can also appear in environmental or scientific writing when something spreads or operates across regional boundaries.

The key idea is that interregional emphasizes what happens across defined geographic areas. It points to movement, contact, or cooperation between regions rather than something limited to just one of them.
