This study tests a hypothesis regarding the connectivity of wh-constructions in spoken discourse data of Turkish-German bilingual children (the ENDFAS/SKOBI corpus), focusing on constructions involving one verbum dicendi: söyle‑ ‘say, tell, verbalise, utter’. It develops a corpus-pragmatic filtering method, based on typological parameters such as headedness and wh-fronting as well as spoken language phenomena related to syntactic and prosodic integration. These criteria are applied in a stepwise manner to identify a subset of findings with potential for grammatical innovation.
