‘留学’ literally combines ‘留’ (to stay, remain) and ‘学’ (to study), meaning ‘to stay abroad for the purpose of studying’. It refers specifically to pursuing formal education—such as undergraduate, graduate, or language programs—in a foreign country. Unlike general travel or work abroad, 留学 implies enrollment in an academic institution and often involves visas, credit transfer, and long-term residence.

This term is commonly used in discussions about educational planning, career development, and cultural exchange. It appears frequently in news reports, university brochures, and family conversations about future goals. While historically associated with elite or high-achieving students, 留学 has become increasingly accessible and diverse in destination countries (e.g., U.S., U.K., Australia, Japan, Germany) and student backgrounds.
