The Boro–Garo languages form four groups: Boro, Garo, Koch and Deori. Boro–Garo languages were historically very widespread throughout the Brahmaputra Valley and in what are now the northern parts of Bangladesh,[2] and it is speculated that the proto-Boro-Garo language was the lingua franca of the Brahmaputra valley before it was replaced by Assamese language, to which it has made major contributions.
The Boro-Garo languages, as reported in the Language Survey of India 1903. The annotations are from Burling (2012) p22.
The Boro-Garo languages were identified in the Grierson's Language Survey of India, and the names of the languages and their modern equivalents are given below in the table.
The linkage of the Boro–Garo languages with Konyak and Jingphaw languages suggest that proto-Boro-Garo entered Assam from somewhere to the northeast.[5] It has been proposed that the proto-Boro-Garo language was a lingua franca of different linguistic communities, not all of who were native speakers,[6] and that it began as a creolized lingua franca.[7] This would account for the highly reduced morphology of Boro–Garo, with what morphology is present mostly being regular, loosely bound, and with transparent etymology, typical signs of recent origin.[8]
[edit]The Boro-Garo language Family Tree (Burling, 2012). Deuri, 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.
Jacquesson (2017:112)[2] 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.
Jacquesson (2017)[2] 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.

^"Briefly, I propose, following a suggestion by Burling (2007), that the Proto-Boro-Garo first as a lingua franca used for communication across the various linguistic communicates of the region and its striking simplicity and transparency reflect a period when it was widely spoken by communities for whom it was not a native language."
