Mongsen Ao language

Mongsen Ao is a member of the Ao languages, a branch of the Sino-Tibetan languages, predominantly spoken in central Mokokchung district of Nagaland, northeast India. Its speakers see the language as one of two varieties of a greater "Ao language," along with the prestige variety Chungli Ao.

A chapter in the anthropological monograph of Mills (1926) provides a grammatical sketch of the variety of Mongsen Ao spoken in Longjang village. Coupe (2003) is one of the few acoustic studies published on a Kuki-Chin-Naga language (only three exist). Coupe (2007) is a reference grammar of the language, based on a revision of his PhD dissertation (Coupe 2004).
