The dative is one the five cases of the Ancient Gk. nominal system. It is the result of a complex syncretic process, involving the Indo-European dative, locative and instrumental, which occurred in different periods of the Gk. language. As a consequence of such syncretism, the Gk. dative encodes a wide range of syntactic functions and semantic roles, in part typical of this case, in part inherited from the Indo-European instrumental and locative. This article provides a brief overview of the chief grammatical and semantic uses of the dative, which, following traditional descriptions, is divided into three main parts, devoted to dative ‘proper’, locatival and instrumental uses respectively.
