The words "abroad" and "overseas" are often used interchangeably, leading to confusion for English learners. However, there is a subtle difference. "Abroad" generally refers to any foreign country, regardless of whether it's across the sea or not. "Overseas," on the other hand, specifically refers to countries that are across the sea. Therefore, all overseas countries are abroad, but not all countries abroad are overseas.

Let's look at some examples:

• "She's traveling abroad this summer." This sentence implies she could be traveling to any foreign country—by plane, train, car, or even walking across a land border.
• "She's traveling abroad this summer." This means the same as the above.
• "He's working overseas in Japan." This sentence specifically implies that he's working in a country across the sea from his home country.
• "He's working overseas in Japan." This means the same as the above.
• "My family lives abroad in Mexico." This sentence works because Mexico is a foreign country, even though it's not across the sea from all countries.
• "My family lives abroad in Mexico." This means the same as the above.

While the difference may seem minor, using the correct word demonstrates a more nuanced understanding of the English language. Consider the context carefully when choosing between "abroad" and "overseas."

Happy learning!
