Based on
mutual intelligibility, Gates (2014) considers there to be five Gyalrong languages: •
Situ (Chinese:
Situ, 四土话) or less precisely Eastern Gyalrong •
Japhug (Chinese:
Chapu, 茶堡) •
Tshobdun (Chinese:
Caodeng, 草登; along with Zbu, next, also called
Sidaba) •
Zbu (Chinese:
Ribu, 日部, also Rdzong'bur or Showu) • Gyalrong (south-central) Situ has more than 100,000 speakers throughout a widespread area, while the other three languages, all spoken in
Barkam, have fewer than 10,000 speakers each. They are all
tonal except for
Japhug. Most early studies on Gyalrong languages (Jin 1949, Nagano 1984, Lin 1993) focused on various dialects of Situ, and the three other languages were not studied in detail until the last decade of the 20th century. The differences between the four languages are presented here in a table of cognates. The data from Situ is taken from Huang and Sun 2002, the Japhug and Showu data from
Jacques (2004, 2008) and the Tshobdun data from Sun (1998, 2006). : Gyalrong languages, unlike most Sino-Tibetan languages, are polysynthetic languages and present typologically interesting features such as
inverse marking (Sun and Shi 2002, Jacques 2010), ideophones (Sun 2004, Jacques 2008), and verbal stem alternations (Sun 2000, 2004, Jacques 2004, 2008). See
Situ language for an example of the latter. ==Demographics==
