More and more people are becoming multilingual. There are many advantages to speaking several languages, but the potential downsides are discussed far less often. They’re frequently only noticed later in life. That’s why it’s important to understand the processes that affect our languages already during the learning process itself.
Imagine that after years of effort, you’re standing there speaking a new language fluently. One day your brother calls from your home country. As you try to tell him what you’ve been up to lately, you suddenly get stuck on simple words you used to use without thinking. What happened to your vocabulary? The words from years of conversations, texts, and presentations?
Language attrition: when your native language weakens
This is called language attrition, and it refers to a gradual weakening of a language due to reduced use. Your native language doesn’t necessarily disappear, but certain words and expressions can become harder to recall. For many people, this can be a surprising experience, especially since one’s native language is often closely tied to identity, memories, and experiences.
For some, it’s a conscious choice to leave their language behind, but for many others, staying connected to their linguistic roots matters deeply. Becoming part of a new society doesn’t have to mean giving up your native language.
Language transfer: how languages influence each other
To understand why languages affect one another, we need to look at another process called language transfer. This describes how knowledge from one language influences the learning and use of another.
This transfer can be positive. Similarities between languages can make it easier to understand and more quickly pick up new words and grammatical structures. But it can also be negative. Differences between languages can lead to what’s known as interference, where structures from one language carry over into another in ways that create errors.
Language transfer also works in both directions. The more we use a new language, the greater the impact it can have on our first language. New ways of expressing things and new structures can gradually begin to influence the old ones.
Balancing languages: how bilingualism affects the brain
This doesn’t mean that language influence is only a problem, though. By understanding how languages interact, we can use these same processes to our advantage.
One key strategy is to keep actively using your native language through conversation, reading, writing, or media. But there are also methods that can be built directly into the language-learning process itself.
You can think of language learning as a balance board. To maintain balance, both sides need attention. One language can support the other, but if all the energy goes into just one, the other risks weakening.
Strategies for learning a new language without losing your native one
Learners who consciously analyze language systems tend to handle language transfer better. There are strategies that can reduce negative transfer while keeping both language systems clearer.
- Compare grammar and syntax between languages — when you learn something new in one language, actively try to see how it differs from your native language. It often becomes clearer why certain mistakes happen when you compare them directly.
- Identify false friends — there are words that look almost identical in two languages but mean different things, and they can easily trip you up if you’re not paying attention.
- Notice your transfer errors — when you make a mistake in a new language, pause and ask yourself if this did come from my other language? It helps you spot patterns in your mistakes.
- Build bilingual word maps — write or think of words from both languages side by side, so you clearly connect the meanings instead of keeping them separate.
- Translate ideas in both directions — take a thought and try to express it in both languages. This trains you to switch between languages naturally.
- Notice similarities and differences between languages — sometimes languages express the same thing in completely different ways, and that can give you new ways of understanding both language and culture.
Why conscious awareness is the key to multilingualism?
Learning a new language doesn’t have to mean losing your first one. On the contrary, conscious language use can help develop both. The better we understand how the brain acquires, stores, and uses linguistic knowledge, the greater our chances of preserving what we already know while learning something new.
