Specific language impairment in Turkish: evidence from case morphology in Turkish-German successive bilinguals.

Language disorders, and Specific Language Impairment (SLI), have been extensively studied in a number of different, though thus far almost exclusively Indoeuropean, languages. For other languages such as Turkish, Vietnamese, or Arabic, however, findings on the outcome of SLI are rare. In this context, the growing number of migrant children in European countries with a variety of first languages can be seen as a challenge to linguistics and to language assessment: The lack of empirical findings on SLI in these languages brings up the question of how the impairment is manifested in bilingual children with a migrant background.
