Interfaces in the returnees’ heritage language: Is the complete (re-)activation possible?

Aims and objectives/purpose/research questions: The aim of this study is to examine whether the complete (re-)activation interface domains in heritage language (HL) possible or interfaces are likely preserve features typical for HL even after many years residing country origin. Design/methodology/approach: We present group analysis direct object marking Turkish, which a morphology-syntax-pragmatics interface, Turkish-German returnees, who returned Turkey puberty have been minimum 10 maximum 34 years, compare them with control consisting Turkish speakers living all their lives. Data analysis: data were collected using narrative task, completion task grammaticality judgement analysed both quantitatively qualitatively. Findings/conclusions: revealed that returnee participants used case-marking on objects productively depending discourse syntactic position Turkish. However, performance tasks diverged from those group. These findings can be considered as piece evidence stay obstinate may return Originality: suggests relevance Interface Hypothesis process (re-)activation. Significance/implications: contributes research development returnees
