对外国语言的研究使不同语言和文化背景的人们之间的交流成为可能，并促进了跨文化的理解。由于语言是表达文化观点和共享社会互动的主要手段，因此外国语言和文学的学生能够发展文化见解，语言和文学敏感性，并意识到其他人无法获得的世界观以任何其他方式。通过对另一种语言体系的了解以及对语言和文化相互依存的理解，外语使用者还能够客观地查看其母语和文化，并允许这种理解为他们与其他文化的人们的交流提供信息。
The study of foreign languages makes possible communication among peoples of different linguistic and cultural backgrounds and fosters intercultural understanding. Since language is the primary means by which cultural perspectives are expressed and social interactions are shared, students of foreign languages and literatures are able to develop cultural insights, linguistic and literary sensitivity, and an awareness of other peoples' world views that are not available in any other way. Through knowledge of another linguistic system and appreciation of the interdependence of language and culture, speakers of foreign languages are also able to view their native language and culture objectively and to allow that understanding to inform their communication with people from other cultures.
