A typical heritage language learner has learned their heritage language to some extent in childhood from parents and relatives, but they’ve become more proficient in the language that dominates where they’ve grown up and been formally educated.
The question they face is how they can develop their heritage language from their current level to higher levels of proficiency.
Heritage language learning is quite a complex area that encompasses a range of issues, and I don’t pretend to be an expert on it.
However, seeing a couple of questions recently from heritage learners on the subreddit r/languagelearning, I felt obliged to offer some suggestions based on my experience and knowledge of language acquisition.
To me the difficulties these posters express appear to be consequences of the influence of “traditional” language learning with its focus on language itself, and they point to the advantages of comprehension-based approaches such as Automatic Language Growth (ALG) that focus on understanding and communicating meaning.
