Definition
Group of language varieties (first language, regional language, languages learned at school or in visits abroad), mastered by the same speaker, to different degrees of proficiency and for different uses. This individual repertoire changes over the course of an individual’s lifespan (acquisition of new languages, “forgetting” languages learned).
