In this paper, we give an account of dative functions in a number of Iranian languages from a typological perspective. To analyze the functionality of dative markers in the selected languages, we follow a semantic map approach and take Haspelmath’s map of dative functions as a typological grid to examine our data. We collected our data from descriptive grammars and, for Ossetic and Wakhi, from interviews. The data show that five additional connections should be added to the semantic map of dative functions; these connections are confirmed by data from at least three languages within the Iranian language family. The main semantic property for the dative in Iranian languages is indirect affectedness. Moreover, in some languages spatial functions of the dative are also attested. The distribution of dative functions is mainly explained by the preservation of the oblique case and the areal distribution. In addition, in some languages, a grammaticalization cycle is observed, as a result of which purportedly beneficiary markers are transforming into dative markers.
