Kinship terminologies reveal ancient contact zone in the Hindu Kush

The Hindu Kush, or the mountain region of northern Pakistan, north-eastern Afghanistan and the northern-most part of the Indian-administered Kashmir region, is home to approximately 50 languages belonging to six different genera: Indo-Aryan, Iranian, Nuristani, Sino-Tibetan, Turkic and the isolate Burushaski. Areality research on this region is only in its early stages, and while its significance as a convergence area has been suggested by several scholars, only a few, primarily phonological and grammatical, features have been studied in a more systematic fashion. Cross-linguistic research in the realms of semantics and lexical organization has been given considerably less attention. However, preliminary findings indicate that features are geographically bundled with one another, across genera, in significant ways, displaying semantic areality on multiple levels throughout the region or in one or more of its sub-regions. The present study is an areal-typological investigation of kinship terms in the region, in which particular attention is paid to a few notable polysemy patterns and what appears to be a significant geographical clustering of these. Comparisons are made between the geographical distribution of such patterns and those of some other linguistic features as well as with relevant non-linguistic factors related to shared cultural values or identities and a long history of small-scale cross-community interaction in different parts of the region.
