Bodish, named for the Tibetan ethnonym Bod, is a proposed grouping consisting of the Tibetic languages and associated Sino-Tibetan languages spoken in Tibet, North India, Nepal, Bhutan, and North Pakistan.
It has not been demonstrated that all these languages form a clade, characterized by shared innovations, within Sino-Tibetan.
[3] More recent classifications omit Rgyalrongic, which is considered a separate branch of Sino-Tibetan.
Languages regarded as members of this family include Bumthang (Michailovsky and Mazaudon 1994; van Driem 1995), Tshangla (Hoshi 1987; Andvik 1999), Dakpa (Lu 1986; Sun et al. 1991), Zhangzhung (Nagano and LaPolla 2001), and maybe Zakhring (Blench & Post 2011).
As for grammars of the East Bodish languages, there is Das Gupta (1968) and Lu (2002).
