International is an adjective that describes something that involves two or more countries, like international laws that multiple countries obey, or an international flight from France to Japan.

Break international into two halves to understand its meaning. The first half is the prefix inter-, which means “among,” or “between.” In the second half, you can see the word nation. Put them together and the word literally means “among or between nations.” Driving from the United States into Canada is an international road trip since you travel from on nation to another, and an international conference has guests from all over the world.
