How Bilinguals Benefit from Language Diversity AB - Bilingual children’s first two languages are often characterized as majority languages (ML) and heritage (HL) languages, since they can develop in a different pace: the HL becomes the “weak” language with increasing age, especially when time outside the family increases. Our study compares longitudinal data of seven French-German/Italian children (age range 1;4–5;4) who acquire French as an HL or ML with the respective groups of monolingual peers. Language competence was assessed via MLU. The main results are: Surprisingly, HL French develops similarly to ML French and monolingual French. By contrast, German and Italian as HLs develop less target-like than their monolingual peers and as ML languages. We explain these results on the basis of language diversity and variety of contacts.
