Could it be that the human brain evolved to be multilingual and that those who speak only
one language are not exploiting their full potential? On an average, people in the world are
multilingual, suggesting that the human brain is capable of handling multiple tongues.
Languages evolved and changed over the course of time due societal necessities and
influences. As humanity kept evolving, different groups of early humans spoke different
languages and dialects of it. In order to communicate with other groups, for trade, travel and
so on, it would have been necessary for some to speak other tongues.
There was a school of thought that bilingual children would be confused speaking two
languages, have lower level of intelligence, low self-esteem, behave in deviant ways, develop
a split personality and even become schizophrenic. It was a view that persisted until recent
times, discouraging many immigrant parents from using their own mother tongue to speak to
their children. However, that was from the sceptics.
The research in the last decade by neurologists, psychologists and linguists, using the latest
brain-imaging tools, is revealing a swathe of cognitive benefits for bilinguals and
multilinguals. It goes to prove that our intellect has more potential than otherwise thought to
Most Indians speak at least 3 languages: mother tongue, regional language of the work place
or a version of widely spread vernacular language (Hindi) and English. Language
connections develop relationships with other factors. I would like to quote my personal
experience here: being multilingual, my emotions are better conveyed and received when I
voice them in my mother tongue, Thamizh. Learning and teaching French and its culture
helped me evolve as a better person, appreciating my own language and culture even more.
Multilingualism has been shown to have many social, psychological and lifestyle advantages.
Moreover, researchers are finding numerous health benefits from speaking more than one
language, including faster recovery from brain-stroke and delayed onset of dementia. A
superior ability to concentrate, solve problems and focus, better mental flexibility and
multitasking skills are, of course, valuable in everyday life. Living in an era of self-learning,
reap the benefits by buckling up and continuing your journey of learning a new language to
delay the aging process.
In a world that is losing languages faster than ever – at the current rate of one a fortnight
(science.org 10.1126/article.22513) , half our languages will be extinct by the end of the
century. It begs a serious question as to what will happen if the present rich diversity of
languages that are spoken across the world starts to disappear and most of us end up speaking
only one or two? What impact does it have on the human species on the whole? I will leave
this thought with you to ponder, and introspect on, and ultimately make the prudent choice of
action in not letting it happen.
