The Barito subgroup was first proposed by Hudson (1967),[1] comprising the three branches East Barito, West Barito, and Mahakam (Barito–Mahakam). It is thought by some to be a Sprachbund rather than a genuine clade. For example, Adelaar (2005) rejects Barito as a valid group despite accepting less traditional groups such as North Bornean and Malayo-Sumbawan.
The Malagasy language originates from the South East Borneo area (modern-day Indonesia), and it has been linked to Ma'anyan within the Southeast Barito group,[2] with Malagasy incorporating numerous Malay and Javanese loanwords.[3][4] It is known that Ma'anyan people were brought as labourers and slaves by Malay and Javanese people in their trading fleets, which reached Madagascar by ca. 50–500 AD.[5][6][7] Based on linguistic evidence, it has been suggested that Malagasy was taken to East Africa between the 7th and 13th centuries.[8][3] It is likely that a separate Malagasy speech community had already formed in Borneo before the early Malagasy migrants settled in Madagascar.[9][10]
