In variational linguistics, concepts of space have always been a central issue. However, different research traditions considering these concepts (such as traditional dialectology and the new socio-dialectological research directions) for a long time coexisted separately. This volume deals with the inter-relationship between different concepts of “linguistic space” from a dialectological, sociolinguistic and folk dialectological point of view. It presents findings mainly from empirical studies which take on these different concepts and examines how they relate to one another.
