Liljegren, Henrik. “The Hindu Kush–Karakorum and Linguistic Areality.” Journal of South Asian Languages and Linguistics, April 22, 2021. 

The article summarizes and discusses the most important results of the Hindu Kush areal-typological research project supported by the Swedish Research Council. In the study, comparable data from 59 language varieties in the region was collected and analysed. The data allowed for classifying each variety along 80 structural features, including phonology, lexico-semantics, grammatical categories, clause structure and word order properties. The emerging picture is one of convergence related to geographical proximity within the region, often cutting across relatedness boundaries. The overall structural analysis lends itself to recognizing six distinct micro-areas, lining up with geo-cultural regions identified in ethno-historical studies. Domain-specific distributions are seen as layers of areality that are each linked to a distinct historical period, and that taken together paint a picture of a region developing from high phylogenetic diversity to today’s dramatically shrinking diversity and resulting structural hegemony. The presentation is supported by examples from individual languages, feature maps and network graphs.
