The Ao languages are a small family of Sino-Tibetan languages spoken by the Ao people of north-central Nagaland in northeast India. Conventionally classified as "Naga", they are not clearly related to other Naga languages, and are conservatively classified as an independent branch of Sino-Tibetan, pending further research.
There are six known Ao languages:
plus undescribed Ao 'dialects' (Yacham, Tengsa) which may turn out to be separate languages (see Mongsen Ao).
