Some good reasons why you should be learning a foreign language
To improve employment potential
Whatever your career goals, knowing a language certainly won't hurt your employability. Chances are that knowing languages will open up employment opportunities that you would not have had otherwise. And you will be able to command a greater salary in the workplace. All else being equal, knowing languages gives you an edge over monolingual applicants competing for the same jobs.
To increase native language ability
Research shows that knowledge of other languages boosts students' understanding of languages in general and enables students to use their native language more effectively. This applies to specific language skills as well as overall linguistic abilities. Foreign language learners have stronger vocabulary skills in English, a better understanding of the language, and improved literacy in general. Higher reading achievement in the native language as well as enhanced listening skills and memory have been shown to correlate with extended foreign language study.
To sharpen cognitive and life skills
Because learning a language involves a variety of learning skills, studying a foreign language can enhance one's ability to learn and function in several other areas. Children who have studied a language at the elementary level score higher on tests in reading, language arts, and math. People who have learned foreign languages show greater cognitive development in areas such as mental flexibility, creativity, and higher order thinking skills, such as problem-solving, conceptualizing, and reasoning.
To increase global understanding
Learning another language gives the learner the ability to step inside the mind and context of that other culture. Without the ability to communicate and understand a culture on its own terms, true access to that culture is barred.
To appreciate international literature, music, and film
A translation of a text can never be fully true to the intent, beauty, style, and uniqueness of its original. A translation is always to a large degree subject to the interpretation of the translator, not least because some elements of languages simply don't have translations in other languages. Word plays, metaphors, innuendos, cultural references and culturally loaded vocabulary words, and formulations unique to the original language often get lost in translation. To be able to fully appreciate literature, theater, music, and film in other languages, one must be able to access them in their original form.
To make travel more feasible and enjoyable
Though it's possible to travel to foreign countries without speaking the native language, your experience will be largely shaped by your ability or inability to see beyond the surface of the culture. When you lack the ability to communicate in the native language, you can not fully participate in day-to-day life, understand the culture, or communicate with the people. The language barrier can be anywhere from frustrating to downright dangerous. When you know the language, you have the comfort of being able to successfully navigate all sorts of situations, like order meals in restaurants, ask for and understand directions, find accommodations and perhaps negotiate cheaper prices, and meet and talk with natives, to name only a few. In most countries, people will appreciate attempts to use their language. You will be able to communicate more completely and have a deeper, more satisfying travel experience.
To expand study abroad options
For advanced language students, the opportunities are even greater. Applicants at the advanced skill level can participate in programs that allow them to be fully immersed and integrated into the academic and social life of the country in which they are studying.
To increase understanding of oneself and one's own culture
Knowing another language and culture affords you the unique opportunity of seeing yourself and your own culture from an outside perspective. There are aspects of your language, yourself, your life, and your own culture that you accept as absolute and universal or that you have never even considered until you encounter a culture and people who do things in a much different way than you're used to. Contact with other languages and cultures gives you the unique opportunity to step outside your familiar scope of existence and view your culture's customs, traditions, and norms as well as your own value system through the eyes of others.
To make lifelong friends
Knowing other languages effectively increases the number of people on the globe with whom you can communicate. And people who speak other languages fully appreciate the effort and desire learners expend to get to know their culture and to communicate with them. Whether through meeting foreign exchange students on your campus or local immigrants in your community, whether getting to know natives or international students while studying abroad, or whether establishing a connection with a pen pal in another country, your ability to speak other languages and your interest in other cultures can connect you deeply with people around the globe.
