There are many advantages in speaking two languages.
1.Access to a larger world: When you learn a language you also learn the culture. Being able to speak two languages means you are able to speak to people in a different cultural and linguistic context. Bilinguals can use the right language with the social codes that go with the language. In other words you are able to step into another culture. Rudolf Steiner a famous pedagogue says: “Each language says the world in its own way”.
2.Better ability to focus : Bilinguals find it easier to focus and can avoid distractions (Dr. Judy Willis, 2012). Indeed, the part of the brain called the executive function, which is used for staying focused has proven to be stronger in bilinguals. Every time a bilingual speaks, both languages are actually active, and the brain has to work to suppress one language while the other is being used. That mechanism employs the executive function of the brain more regularly in bilinguals which makes it become more efficient.
3.Intellectual Gymnastic: Learning another language stretches your mind intellectually. When you learn another language you have to focus on the structure of sentences, you have to recognise sound patterns and make inferences. Research even shows that learning a language would help delay Alzheimer disease (Dr. Ellen Bialystok).
4.Better at multitasking : Bilingual kids can switch from one activity to another faster and are better at doing multiple tasks at once than monolinguals (Ellen Bialystok, 1999). That is thanks to the executive function of the brain, which gives bilinguals better cognitive control over information that allows them to switch tasks.
5.Linguistic facilities: Being bilingual helps you to learn another language. As you are constantly switching from one language to another you become accustomed to expressing yourself in a different way. Moreover, you have been exposed to two sets of sound patterns rather than one. This gives you more chances to encounter known sounds in the new language. All this combined makes learning an additional language easier.
6.Deep understanding of the concept of “language”: Bilinguals have a deeper appreciation of what is a language. They know that there is more than one way to label a word and that a word can have different connotations. As Professor Clyne says: “They [Bilinguals] have a better sense of the arbitrary nature of words, and the difference between form and meaning.”
7.More job opportunities: Fluency in more than one language can open many doors.
8.Travel: Being fluent in more than one language creates opportunities for travel.
