The series is a platform for contributions of all kinds to this rapidly developing field. General problems are studied from the perspective of individual languages, language families, language groups, or language samples. Conclusions are the result of a deepened study of empirical data. Special emphasis is given to little-known languages, whose analysis may shed new light on long-standing problems in general linguistics.

The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks as well as studies that provide new insights by building bridges to neighbouring fields such as neuroscience and cognitive science. The series considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language.
