You Can Still Learn a Second Language Well as an Adult

Many believe in a critical period for language learning during childhood, after which our ability to learn languages is fixed. This common myth suggests that once we pass a certain age, true fluency becomes out of reach. However, the truth is that this idea is not necessarily true, and scientific studies question its strict limits (Azieb, 2021). 

That being said, it is undeniable that it feels harder for adults to embark on this journey. The difference lies largely in the method, not the capacity. Children learn naturalistically, often fully immersed in the target language environment. For example, in a school setting, students might use the new language in class without ever translating it back into their first language and practice it weekly. In contrast, adult learning is often sporadic, as their various life and career commitments prevent the fixed, consistent schedule that students benefit from (Woodall, 2024). Furthermore, while we are comfortable with a child taking two to three years to reach a comfortable level of fluency, adults often expect immediate results, a key barrier to long-term success.

Yet this adult language adventure offers distinct advantages. Adults learn differently and possess stronger thinking skills, allowing us to employ better learning methods, develop a deeper awareness of language rules, and build a vast vocabulary (Simon, 2024). These are powerful tools children simply don't have, and they can help speed up certain aspects of learning (Woodall, 2024).

Learning a new language as an adult is one of life’s most rewarding adventures. It offers clear benefits, such as improved brain health, and creates amazing opportunities for cultural connection. Don't let a myth define what you can achieve; the only way to find out what you're capable of is to start exploring and trying.
