Kho-Bwa languages
The Kho-Bwa languages, also known as Bugunish and Kamengic, are a small family of languages 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, or alternatively "Bugun–Mey", after its two main members. Alternatively, Anderson (2014) refers to Kho-Bwa as Northeast Kamengic. Both Van Driem and Blench group the "Bugun" (or "Khowa"), the "Mey" (or "Sherdukpen"), and the "Lishpa" (or "Lish ) languages. The Puroik" (or "Sulung") language is included in the group by Van Driem but treated as a language isolate with no genetic relation to Kamengic by Blench. These languages have traditionally been placed in the Tibeto-Burman group by the Linguistic Survey of India, but the justification of this is open to question. The languages have certainly been strongly influenced by the neighboring Sino-Tibetan languages, but this does not necessarily imply genetic unity and may possibly be a purely 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). Classification. The internal structure of the "Kho-Bwa" group of languages is as follows. Lieberherr & Bodt (2017). Lieberherr & Bodt (2017) consider Puroik to be a Kho-Bwa language, and classify the Kho-Bwa languages as follows. Tresoldi et al. (2022). Based on computational phylogenetic analyses from Tresoldi et al. (2022), the phylogenetic tree of Kho-Bwa is roughly as follows: Vocabulary. The following table of Kho-Bwa basic vocabulary items is from Blench (2015). Kho-Bwa
