Are you a mono-, bi-, or multi-lingual household? Would you like your child to grow up speaking more than two languages? Let's take a closer look at multilingualism, its benefits, and how it can affect our at school

What is multilingualism and what are the benefits?  


Put simply, the concept of multilingualism is the use of more than one language, either by an individual or by a group. 

Although every one of us has the potential to become multilingual, it seems we in the US are somewhat lagging behind the rest of the world. In fact, studies show that 75% of Americans only speak English – despite 43% of those surveyed stating that “Americans should know as many languages as possible.." 😶

However, we are fast embracing multilingualism! A 2019 report showed that in nine states, one in four residents now speaks a language other than English at home. In fact, since 1980, the number who speak a foreign language at home grew nearly seven times faster than the number who speak only English at home. 🙌

Bilingualism vs multilingualism

So, what's the difference between bilingualism and multilingualism? While bilingualism is essentially a type of multilingualism, it specifically refers to the ability to use two languages effectively while multilingualism has no upper limit on the number of languages an individual may master. 👄

Benefits of multilingualism

Comprehending multiple languages has been shown to have all sorts of positive effects on an individual from increasing their ability to multitask, to more effective problem solving, enhanced communications skills, boosted working memory, and increased career opportunities.

Outside of cognitive and emotional development, being multilingual has been found to affect the actual structure of the brain! More on that later. 👇


Why is multilingualism important?


Given the rapid technological, economic, and cultural globalization all around us,  multilingualism has never been a more relevant and useful skill, not only to the individual but to society as a whole. 🤝

Helping your child to learn another language (or two!) will promote academic success in the short term and make them a more attractive candidate in the global jobs market in the long term. Not to mention the vital contribution to the furtherment of multicultural and international awareness they will make.


How does multilingualism affect the brain?


Researchers have investigated the various effects of multilingualism on the brain through the field of neurological study. These include how different language systems are physically represented as well as the brain's increased structural plasticity. 

There is a general consensus that multilingual people have a greater density of grey matter in the inferior parietal cortex – that’s the part of the brain that processes language, mathematics, the perception of emotions, and the interpretation of sensory information – all good skills to have! 🧠

Learning a second language can also protect against the onset of Alzheimer’s disease and dementia. Researchers from the University of Ghent in Belgium published a study suggesting that multilinguists exercise their brain in such a way that it can delay general degeneration and the subsequent onset of Alzheimer’s by over 4 years. ✌


Is multilingualism good for children?


The overall impacts of learning multiple languages as a child are as varied and unique as the children themselves. There are several variables to bear in mind such as the number of languages spoken at home, access to formal education, general emotional wellbeing, and many more – but research so far strongly suggests that the positive effects far outweigh the negative. 👍

Multilingualism has been proven to help children develop superior reading and writing skills as it allows them to focus better, decipher the most relevant information, and then remember it more effectively. Overall, multilingual children have stronger analytical, social, and recall skills than their monolingual peers. 💭


How do I teach my child multiple languages?
