Areal sound change and the distributional typology of affricate richness in Eurasia

This paper makes a contribution to phonological typology by investigating the distribution of affricate-rich languages in Eurasia. It shows that affricate-rich and affricate-dense languages cluster areally within Eurasia and have area-specific histories. In particular, the affricate-rich areas of western Eurasia – a ‘European’ area and a Caucasian area – are not the result of contact-induced sound changes or borrowing, while the two affricate-rich areas of eastern Eurasia – the Hindukush area and the Eastern Himalayan area – are the result of contact. Specifically, affricate-dense areas depend on the emergence of retroflex affricates. Moreover, languages outside these affricate-dense areas tend to lose retroflex affricates.
