Des « bilingues scolaires » dans le paysage sociolinguistique breton ?

As an extension of the work carried out in the Breton field about the school bilingualism of young children, this article presents to discussion the relevance of determining and mobilizing a new notion in connection with this research object, the notion of « bilingual pupils ». This idea of conceptualization continues scientific reflections on so-called « early » bilingualism, by addressing the question of the conditions of appropriation or non-appropriation of a minority language, such as Breton, transmitted through schooling. It is then a question of showing how the determination and use of this notion can appear heuristic both on the theoretical level and from the point of view of sociodidactic perspectives.
