“…Turning to comprehension, experimental studies targeting complex sentences in Greek, such as relative clauses and wh-questions, have reported that case marking has a facilitatory effect on the comprehension of these structures. Preschool and school-age monolingual Greek-speaking children make use of case-marking cues to assign thematic roles when parsing complex structures in a way that may accelerate acquisition (Guasti, Stavrakaki, & Arosio, 2012;Sauerland et al, 2016;Stavrakaki, Tasioudi, & Guasti, 2015;Tsimpli & Stavrakaki, 2001;Varlokosta, Nerantzini, & Papadopoulou, 2015). For example, Guasti et al (2012) reported that relative clauses were acquired in Greek-speaking children between the ages of four and five years, almost two years earlier than the Italian-speaking children in their study, a language without case marking.…”
