This chapter focuses on split wh-constructions and provides an answer to the following two questions: (i) why split wh-constructions were widespread in Classical Greek, but are now impossible in Modern Greek; (ii) why splitting of tinos and pianu, both meaning ‘whose’, are exceptions to the rule against wh-splitting in Modern Greek. Section 14.2 introduces some basic facts about hyperbaton in Classical and Modern Greek and outlines the diachronic puzzle. Section 14.3 presents an account of the licensing mechanism behind DP splitting. Section 14.4 provides a diachronic account of the loss of split wh-constructions in Modern Greek. Section 14.5 discusses the question as to why splitting of tinos and pianu is possible, while Section 14.6 concludes.
