Wir wollen an dieser Stelle in Thesenform Prinzipien des toponymischen Vergleichs zwischen Böhmen und Sachsen darlegen, um Anregungen für künftige komparative Forschungen zu geben.

The article continues to discuss the origins and the history of the Saxon place name Leipzig. Several questions are under scrutiny. Starting out from recent research which gives the oldest historical evidence of the place name Leipzig as Lib-, it deals with certain new doubts regarding explanations that try to date the origins of the place name in pre-monolingual times. The question whether one can assume an original Slavonic form to the Slavonic root *lib- is dealt with in detail. The results of this discourse are: Today’s research cannot give a satisfactory explanation that the primary place name is derived from Slavonic. Furthermore, the hypothesis of an existing pre-monolingual form is newly evaluated. In this regard also the formerly existing geographical setting of the area around Leipzig is considered as the deciding motive in naming the place.
