“Learn a language like a child.”
It is one of the most common ideas in language-learning marketing. We are told to play games, absorb language naturally, stop worrying about grammar, avoid analysis, and let the language “sink in.” The promise is usually appealing: if we can recreate the conditions in which children learn, perhaps adults can acquire a language effortlessly too.
There is some truth behind many of these recommendations. Children learn through interaction, repetition, stories, movement, attention, imitation and meaningful experience. Adults can benefit from all of these things as well. Listening carefully to sounds, learning through context, using gestures, playing with language and encountering words repeatedly in meaningful situations can all be excellent components of adult language learning.
The problem begins when a useful learning technique is turned into a theory of what an adult learner should be.
An adult is already a developed person. They arrive at a new language with a history, an identity, an existing language, accumulated knowledge, established concepts, memories, preferences, habits and a particular relationship with effort and failure. They already know a great deal about the world.
An adult knows what hunger is before learning how another language expresses hunger. They know what a dog is before learning the word for dog. They understand what a question is before learning how another language constructs questions. They already understand friendship, embarrassment, distance, politeness, anger, humour, work, family, time and countless other aspects of human experience.
This changes the nature of the learning task.
A child acquiring a first language is developing an understanding of the world while language is simultaneously becoming part of the way that world is represented, organized and communicated. Linguistic development is deeply intertwined with conceptual development, social development, memory and the formation of the self.
An adult learning another language begins somewhere else. The world is already there. A conceptual system is already there. A linguistic system is already there. The adult is often learning new linguistic forms and patterns through which an already-developed world can be experienced and communicated.
That difference matters pedagogically.
We can reproduce some of the conditions associated with childhood learning. We can give adults meaningful experiences, rich input, interaction, stories, movement and opportunities to notice patterns. We can create situations in which language is encountered repeatedly and used for real purposes.
We cannot reproduce the developmental history of childhood.
That distinction is easy to lose because the same activity can occur in both settings. A child and an adult can both point at a dog and hear its name in another language. They can both play a game. They can both imitate a sound. They can both learn through a story.
But the activity does not have the same developmental meaning for both learners.
The child is building linguistic and conceptual knowledge together. The adult already possesses the concept and is connecting another linguistic form to an existing representation. The adult may eventually develop direct, automatic access to the new language, and after years of living through that language it can become deeply embodied and connected to personal memories and experience. But the route into that language began from a fundamentally different place.
This is why “learn like a child” is such an imprecise piece of advice for adults.
It collapses technique, learning mechanism and developmental context into a single idea.
Adults can certainly play. They can learn through experience. They can benefit from implicit learning and pattern recognition. They can develop intuitive access to another language. They can even reach extremely high levels of proficiency.
What they cannot do is become developmentally equivalent to the child they once were.
And there is another reason I find the language of “learning like a child” problematic: it often overlooks the adult’s identity.
Every adult learner has an ego.
I do not mean this in the narrow sense of vanity or self-importance. I mean the person’s existing sense of self: who they believe they are, what they value, what they are good at, what they find difficult, what they want from life, how they relate to other people, what kind of mistakes they are willing to make in public, and what they are trying to become.
That ego is part of the learning environment.
Two adults can want to learn the same language and have completely different reasons for doing so. One may need it for professional competence. Another may want to participate more fully in a relationship. Another may be rebuilding a life in a new country. Another may be fascinated by the culture. Another may simply want to read literature in the original language.
Their goals create different learning priorities. Their histories create different obstacles. Their identities affect how much uncertainty they tolerate, how comfortable they are speaking before they feel competent, how much structure they need, and what kinds of activities they find meaningful.
There is therefore no good reason to strip away the adult in order to teach the language.
The adult learner’s existing self is valuable information.
It tells us what the language is for.
It tells us where the language needs to enter the person’s life.
It tells us what kinds of learning experiences are likely to matter.
It tells us what the learner is willing to invest and what they are trying to achieve.
This has an important consequence for teaching.
The central question should not simply be, “What is the best method for learning a language?”
A more useful question is, “What kind of person is learning this language, and what role does the language need to play in that person’s life?”
Once we ask that question, methodology becomes more flexible and more honest.
A teacher can decide when explicit explanation will help and when experience will be more productive. They can use grammar, conversation, reading, listening, memorisation, pronunciation work, stories, repetition, translation, role-play or immersion according to the learner and the purpose. Different tools become resources rather than competing ideologies.
This also changes how we think about motivation.
Motivation is not a universal substance that a teacher can pour into a learner through the right activity. It emerges from the relationship between the learner, the language and the life they want to lead.
An adult who has a meaningful reason to use a language has something very different from an adult who has been told that learning a language would be “good for the brain.” Someone who wants to build a career in another country has a different relationship with the language from someone who wants to speak to their partner’s family. Someone who wants to become a confident participant in a new community has a different goal from someone who wants to pass an examination.
The language has a different place in each person’s identity.
That is why adult language learning inevitably involves responsibility.
A good teacher can create better conditions. They can provide appropriate input, diagnose difficulties, explain patterns, design useful practice, give feedback and help a learner understand what they are doing.
But the learner still has to learn.
They have to decide what the language means in their life. They have to determine what they are willing to invest. They have to tolerate periods of incompetence. They have to practise. They have to encounter the language repeatedly. They have to make mistakes and continue.
No method can take the learner’s place.
This is where I think some language-learning marketing becomes unintentionally infantilizing. It offers adults an escape from the responsibilities that come with being the person who is learning. It suggests that somewhere there is a method capable of making the difficult parts disappear: the right app, the right immersion system, the right vocabulary technique, the right sequence, the right “natural” approach.
The more attractive the promise, the easier it becomes to believe that successful language learning is primarily a matter of finding the correct system.
For adults, I think the more interesting possibility is almost the opposite.
Take the adult seriously.
Take their history seriously. Take their intelligence seriously. Take their existing knowledge seriously. Take their identity seriously. Take their goals seriously. Take their time seriously.
Then build the learning around the actual person.
Adults do not need to become children again in order to learn languages. They have resources that children do not have: conceptual knowledge, metalinguistic awareness, accumulated experience, deliberate attention, the ability to plan, the ability to reflect on their own learning, and the ability to make conscious choices about what they want a language to become in their lives.
These resources can make adult language learning demanding in particular ways, but they can also make it extraordinarily rich.
The goal of adult language education, then, is not to make adults childlike learners.
It is to help adults use their adulthood intelligently.
A language is entering a life that has already begun.
Good teaching starts there.
