Internationally means involving, affecting, or connecting multiple countries around the world. When something happens internationally, it crosses national borders and includes people or places from different nations.

A company that operates internationally has offices, factories, or stores in many countries. Athletes compete internationally when they travel to different countries for tournaments, like the Olympics or the World Cup. Scientists work internationally when they collaborate with researchers from other nations to solve big problems like infectious disease.

The word helps us distinguish between local, national, and worldwide activities. A student might be the best speller in their class, their state, or even their country, but to compete internationally means facing the best spellers from countries across the globe.

When news is reported internationally, it means media outlets in many countries are covering the same story because it matters to people everywhere. When laws or agreements work internationally, multiple countries have agreed to follow the same rules, like treaties protecting endangered animals or agreements about how to treat prisoners of war.

The word reminds us that we live in a connected world where what happens in one place can matter to people thousands of miles away.
