The origin of Khanty retroflex nasal
Proto-Khanty is traditionally reconstructed with a retroflex nasal phoneme *ṇ, whose origin remains disputed. According to one theory, it is directly inherited from Proto-Uralic. The other theory holds that Proto-Uralic *n, usually preserved as *n in Khanty, sporadically yielded *ṇ. We argue that Proto-Khanty *ṇ results from a regularly conditioned sound change.
