Relative amount of language exposure has been repeatedly shown to be a reliable predictor of bilingual children’s early vocabulary skills in each language. In this talk I will present work on bilingual children who are past the early stages of acquisition (6- to 10-year-olds). I will show that the relative amount of language exposure – operationalized as the language of the community – is a significant predictor of differences in bilingual children’s interpretation of aspects of language that require sophisticated morpho-syntactic, semantic and discourse-pragmatic skills.
