# Siangic languages

The Siangic languages (or Koro-Holon languages) are a small family of possibly Sino-Tibetan languages spoken in Arunachal Pradesh, northeast India. The Siangic languages consist of Koro and Milang.

## Classification

Milang, which has been extensively influenced by Padam (a Tani language), is alternatively classified as a divergent Tani language (Post & Blench 2011). Koro has undergone influence from Hruso (Post & Blench 2011). However, Milang and Koro do not belong to either the Tani or Hrusish groups of languages.
It is unclear whether the Siangic is a branch of Sino-Tibetan or an independent language family that has undergone extensive Sino-Tibetan influence. Post & Blench (2011) note that Siangic has a substratum of unknown origin, and consider Siangic to be an independent language family. Anderson (2014), who refers to Siangic as Koro-Holon instead, considers Siangic (Koro-Holon) to be a branch of Sino-Tibetan rather than an independent language family.

## Reconstruction
### Post & Blench (2011)

The following Proto-Siangic forms reconstructed by Mark Post & Roger Blench (2011:8-9) do not have lexical parallels with Proto-Tani, and are unique to the Siangic branch.
