Why Your Home Language Matters
Research shows that fluency in your home language is the foundation for learning a new one. The stronger your grasp of your first language, the easier it becomes to acquire additional ones.
Studies further reveal that bilingualism and multilingualism bring lifelong cognitive, cultural, and professional benefits.
The Benefits of Bilingualism
Enhanced Cognitive Function
One of the strongest findings from bilingualism research is the boost in executive control functions, such as impulse inhibition and working memory.
From infancy to old age, bilingual speakers show more efficient brain activity in the prefrontal cortex — the area responsible for focus, decision-making, and problem-solving.
Expanded Career Opportunities
In a globalised economy, employers value candidates who can communicate across linguistic and cultural boundaries. Bilingual employees are better equipped to collaborate internationally and serve diverse markets. Research from the University of Bristol even links linguistic diversity to economic growth.
Cultural and Social Cohesion
Language opens the door to culture. Studies confirm that bilingual individuals often display greater empathy and respect for diversity, as they can engage across social and cultural groups more effectively than monolinguals.
Positive Brain Health Outcomes
Bilingualism has been shown to delay the onset of dementia and Alzheimer’s disease by up to five years. This is due to neuroplasticity, which strengthens cognitive reserves and helps the brain find alternate pathways to recall information even as it ages.
Teaching a Second Language
Start Early, But It’s Never Too Late
Research supports introducing a second language between birth and three years, when children are most receptive. However, adults can also achieve fluency through consistent communication and immersion. Both groups learn best through practical, everyday interaction in the target language.
Tips for Teaching Children and Adults
- Exposure is key: Prioritise using the target language during lessons and at home. Encourage learners to interact with fluent speakers.
- Make it fun: Games, songs, and role-playing make learning grammar and vocabulary more engaging.
- Teach the culture: Understanding cultural context deepens language appreciation and helps learners grasp nuance.
- Use multimedia: Films, TV shows, radio, podcasts, and apps are powerful tools to train the ear. (For instance, RM of BTS famously learned English by watching Friends repeatedly.)
Whether for cognitive growth, career opportunities, cultural connection, or brain health, learning and teaching a second language is one of the most rewarding investments you can make. Start early if possible, but remember — it’s never too late to immerse yourself in a new language and expand your world.
