Joseph & Burling (2006) , earlier erroneously called "
Chutia", is the first split and is farthest from the other languages in this group. The original Boro-Garo language of the Chutia people, who currently speak
Assamese, is unknown.
Moran, a language belonging to the
Boro group, was last recorded in the early 20th century and is no longer attested. The
Rabha group is also called the
Koch group. Thus, there are four sub-groups within this classification of the Boro-Garo languages: Deori, Boro, Garo and Rabha/Koch. Joseph & Burling (2006:1-2) classify the Boro–Garo languages into four major groups. Wood (2008:6) also follows this classification. •

Boro languages:
Boro,
Kokborok,

Rabha (Kochic) languages:
Koch,
Rabha, Wanang,
Atong, and
Ruga Jacquesson (2006) Jacquesson (2017:112) classifies the Boro-Garo languages as follows, and recognizes three major branches (Western, Central, and Eastern). The
Koch languages and
Garo are grouped together as Western Boro-Garo. • Western •
Garo, •
Rabha,
Koch •
Central •

Dimasa,

Kokborok • Eastern •
Deori Jacquesson (2017) believes that the Boro–Garo languages had arrived in their present location from the southeast, and notes similarities shared with
Zeme languages and
Kuki-Chin languages. ==Reconstruction==
