This volume, written in German, deals with the use of the local cases in Tocharian A and Tocharian B, Indo-European languages of the Tarim Basin, Eastern Central Asia, of the 6th - 9th centuries AD. Tocharian differs typologically from most of the other Indo-European languages in that it is basically inflectional-agglutinative. This tendency is dominant in the case system: generally, local relations are expressed by local cases alone, and adpositional phrases are used only in order to express more specific local relations. The study concentrates on the local cases expressing location and direction (i.e. oblique, allative, perlative, and locative) in the following contexts: - case constructions expressing concrete or abstract local relations - case constructions expressing temporal relations - adpositional constructions expressing local and temporal relations. The uses of the local cases with various reference objects is presented. A theoretical discussion of the nature of the respective local cases and a reconstruction of a possible evolution of the function of the cases from Proto-Tocharian to Tocharian A and Tocharian B concludes this study. Locality in Tocharian is a field in which almost no research has been carried out, and in this sense this study fills a slot within the field of Indo-European syntax. This book is of special interest to historical and comparative linguists, especially those working with Indo-European languages, to general linguists interested in localism and specialists in Central Asian languages.
