This volume 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 to 9th centuries AD. Tocharian is basically inflectional-agglutinative, and this ten-dency is dominant in the case system. This study concentrates on the local cases expressing location and direction (i.e. oblique, allative, perlative, and locative) in case constructions and adpositional phrases expressing local and temporal relations. A theoretical discussion of the nature of the local cases and a possible evolution of their functions from Proto-Tocharian to Tocharian A and Tocharian B concludes this study.
