The volume provides a comprehensive empirical examination of linguistic convergence in the Balkans. By mapping over 100 linguistic and sociolinguistic features across 60 languages and dialects, the book rigorously tests the concept of a linguistic area. Each feature is visually represented with maps and analyzed in summaries co-authored by an international team of experts. In addition to the printed volume, the Atlas of the Balkan Linguistic Area Online enhances accessibility by offering illustrative examples for each language dataset, making it an essential resource for scholars of language contact and typology.
