Since Ossetians have long existed in isolation from the rest of the Iranian world, their language has a unique status among Iranian languages. On the one hand, it has preserved a number of archaic morphological, phonological, and syntactic features, for example, a complex system of oblique moods. On the other hand, due to centuries of close contact of Ossetians with speakers of indigenous languages of the Caucasus, Ossetic has developed some innovative traits, for example, a rich agglutinative case system with several spatial forms. The knowledge of Ossetic is thus indispensable not only for comparative work on Iranian languages, but also for the typology of language contact and for the study of the Caucasian linguistic area. This volume for the first time brings together specialist contributions that present the state-of-the-art of modern scholarship on Ossetic.
