Root Explanation
Binational → It is formed from "bi-" (meaning two) and "national" (from Latin "natio", meaning nation or people). The word "binational" refers to something that involves or relates to two nations.
Memory Tip
Think of 'bi-' meaning two, and 'national' relating to a nation — so binational means involving two nations.
