Did you know that the United States has 48 conterminous states?

Yeah, I learned that in geography class. It's interesting how they all share borders.

I wonder how different it would be if Alaska was conterminous with the other states.

That would definitely change the map and how we travel around!

Root Explanation

Conterminous → It is formed from "con-" (meaning together) and "terminus" (from Latin, meaning boundary or limit). The word describes areas that share a common boundary or are adjacent to each other.

Memory Tip

Think of areas that are 'together' ('con-') at their 'boundaries' ('terminus') — that's why conterminous means sharing a boundary.
