Kho-Bwa languages

The Kho-Bwa languages, also known as Kamengic, are a small family of languages, or pair of families, spoken in Arunachal Pradesh, northeast India. The name Kho-Bwa was originally proposed by George van Driem (2001). It is based on the reconstructed words *kho ("water") and *bwa ("fire"). Blench (2011) suggests the name Kamengic, from the Kameng area of Arunachal Pradesh. Alternatively, Anderson (2014) refers to Kho-Bwa as Northeast Kamengic.

Both Van Driem and Blench group the Sherdukpen (or Mey), Lishpa (or Khispi), Chug (Duhumbi) and Sartang languages together. These form a language cluster and are clearly related. The pair of Sulung (or Puroik) and Khowa (or Bugun) languages are included in the family by Van Driem (2001) but provisionally treated as a second family by Blench (2024).

These languages have traditionally been placed in the Tibeto-Burman group by the Linguistic Survey of India. Jackson Sun, George van Driem, and multiple handbooks and language classification databases after them also label Kho-Bwa languages as Tibeto-Burman or otherwise Sino-Tibetan. Roger Blench, however, does not accept a Sino-Tibetan origin of these languages, claiming that similarities to such could instead be due to an areal effect.

The entire language family has about 15,000 speakers (including Puroik) or about 10,000 speakers (excluding Puroik), according to estimates made during the 2000s.

Word lists and sociolinguistic surveys of Kho-Bwa languages have also been conducted by Abraham, et al. (2018).
