Many people, even if they’ve only learned one foreign language, may only visit the country where the language is spoken once a year or once every few years, so it can be hard to maintain or improve those language skills. Not being able to maintain a language can lead to something many multilingual people fear: language attrition, or the weakening or loss of a language. In my case, I claim to have 16 languages, and so language attrition is a concern.
