abroad
In or to a foreign country, outside your own nation.
When you travel abroad, you go to a foreign country, crossing an international border to visit a place with different customs, languages, and ways of life. If you live in Texas and visit France, you're traveling abroad. If your family lives in Kenya and takes a trip to Brazil, that's going abroad too.
People study abroad to attend school in another country for a semester or year. Businesses operate abroad when they open offices or factories in foreign nations. Soldiers serve abroad when stationed in other countries.
You might hear someone say “news from abroad” to mean news from foreign countries, or that rumors are spreading abroad (meaning widely or everywhere). When a famous musician tours abroad, they perform in countries other than their home nation.
Going abroad often means experiencing new foods, hearing unfamiliar languages, and discovering how people in other parts of the world live. It's different from traveling within your own country: a trip from California to New York isn't going abroad because you're staying within the United States, but a trip from California to Mexico or Canada is.
