„Was heißt denn das, Mama?“ Sandra Ballweg fostering language acquisition multilingualism erwerbsförderliche Interaktion Interaktion in mehrsprachigen Familien Mehrsprachigkeit interaction in multilingual families The family is a formative place of linguistic socialisation for children and forms the basis for further language acquisition, so that research into linguistic practices and multiple language acquisition in multilingual families also contributes to understanding language use and language acquisition in kindergarten and school. From the perspective of interactional sociolinguistics, this article uses a case study based on audiographed family interactions to investigate how multilingual practices that foster language acquisition are co-constructed between parents and a child in a German- and Turkish-speaking family. In the date, it becomes evident that the child has a pivotal role in co-constructing interaction and implicitly reinforces practices that foster language and discourse acquisition, expecially responsiveness, contingency and a demanding and supportive attitude.
