Mother Language Day: Why learning a foreign language is important -The Asian Age

International Mother Language Day has been celebrated every year since February 2000 to promote linguistic and cultural diversity and multilingualism. The importance of linguistic diversity and multilingualism in an increasingly globalized world is vital to achieve meaningful communication between nations and strengthen the unity and cohesion of societies. Today, there are around 7,000 languages in the world, and an increasing number of situations in which two or more languages co-exist and are indispensable in everyday communication. UNESCO's decision to celebrate International Mother Language Day derives from the importance of linguistic diversity and the need to maintain and revive minority languages. Through learning languages, even just by mastering a second language, we develop a fuller awareness of linguistic and cultural traditions (UNESCO, n.d.). And besides the obvious practical benefits learning a foreign language provides, it has been demonstrated to improve memory and brain power and delay the onset of Alzheimer's and dementia.

Bilingualism, even when acquired in adulthood, can have a positive effect on the brain. Students who speak more than one language tend to outperform peers in math and reading (French Immersion School of Washington, n.d.; Anne Merritt, 2013), and are more adept at focusing on relevant information by ignoring irrelevant and misleading stimuli. This can be due to the fact that by learning another language, we have to switch back and forth between two distinct systems of rules, challenging the brain to recognize and work out meaning. For this reason, bilingual students learn to become critical thinkers and perform better at problem-solving tasks. The brain has also been likened to a muscle since it is said to function better with exercise. Language learners need to memorize rules and vocabulary and thus strengthen their cognitive muscles, making them better at memorizing lists and sequences (Anne Merritt, 2013).

Learning a second language can also develop mother tongue skills. Generally, not much attention is paid to the grammatical structures of our native tongue, but once we start to focus on the mechanics of a second language: grammar, conjugations and sentence structure, our awareness of our L1 improves.

These transferable skills give bilingual students a greater insight into their mother tongue, thus making them more effective communicators as well as better writers. Bilingualism's effects also extend into later life. Recent studies have shown that bilingual patients were more resistant to the onset of dementia. On average, individuals with a proficiency in two or more languages developed dementia 4.5 years later than monolingual ones (SuvarnaAlladi et al., 2013; Anne Merritt, 2013). But aside from the positive effects on our cognitive process, learning a second language opens the door into a particular culture, broadening our understanding of a race and culture, and making us more appreciative of other perspectives. Once I started to learn a second language, I began to experience how learning about another culture, in my case Mexico, has enabled me to achieve a significantly more profound understanding and appreciation of my own. As a Brit living in Mexico, I feel a stronger connection to my heritage which I took for granted when living in England. Not only that, I now have access to an assortment of literature, movies and music in their original form, giving me the opportunity to view the world from different vantage points. Learning a second language has been a truly rewarding experience, and has enabled me to build deep and meaningful relationships with people in foreign communities as well as becoming more flexible and creative in my ways of thinking. It has also opened up a whole world of opportunities when it comes to travel and I have been lucky enough to have had the chance to visit local indigenous communities where Spanish is not their first language. Without a doubt, bilingualism and multilingualism provide the possibility to bridge both the linguistic and cultural gap between countries as well as being a great asset to the cognitive process.
