What if I told you that language learning begins long before a child says their first word?
I recently attended two conferences at the University of Geneva, as I was curious to understand how our brains acquire language, from the womb through to adulthood, and how multilingualism shapes cognition.
My main takeaway from the conference was clear: language learning begins much earlier than we often imagine and shapes far more than communication. As an English as an Additional Language (EAL) teacher, I was reminded that supporting language development means understanding the whole child — their brain, background, potential, and way of making sense of the world.
And one of the most striking insights from the first conference session, First Words, New Languages?, was that language acquisition begins in the womb.
So, how does this language learning happen?
From scratch, children must learn to process the sounds of their mother tongue, gradually acquire and produce thousands of words, and learn the rules for combining words to form sentences.
This all serves to strengthen the various communicative functions of language and conversational skills.
Key insights on this influential development period include:
Recent neuroscience research confirms that prenatal exposure to language influences brain activity immediately after birth. Newborns are not blank slates—they are already tuned to the rhythm and structure of the language they hear most.
Language development accelerates rapidly in early childhood, with the following benchmarks:
An interesting takeaway is that children do not just memorize—they actively construct language, even inventing words based on patterns they detect.
I understand much better now that interaction matters more than perfection. Conversations, storytelling, and reading at home are essential for language development.
I had a strong personal interest in the second conference. I come from a multilingual background, and while I have done a lot of research on the subject, I am always keen to keep up with the latest thinking - we never stop learning. So, let’s dive in.
Despite long-standing myths, multilingualism is not harmful - it is transformative. Outdated beliefs once linked bilingualism to cognitive deficits.
For example, one of the most persistent myths that I frequently hear is that being exposed to several languages harms a child’s intellectual development.
However, from the experts at this conference session, I discovered that multilingual children often demonstrate advantages over monolingual children in selective attention, the ability to adapt to new rules, and metalinguistic awareness.
Recent neuroscience research also shows that:
So, speaking multiple languages is essentially a daily workout for the brain!
Language learning is not an isolated skill—it is part of a broader adaptive system:
Even emotional expression can shift across languages—many people report feeling less emotionally intense in a second language, highlighting how deeply language and cognition intertwine.
As an EAL teacher, I have come to see that understanding language development shapes both my classroom practice and the way I support each child as a learner.
It allows me to detect early developmental delays, respond more effectively to individual needs, rethink education in multilingual contexts, and better appreciate the brain’s extraordinary adaptability.
Language is not something we simply learn—it is something our brains are designed to absorb, adapt, and refine from the very beginning of life. It shapes who we become.
