The position of the Tamanic languages, usually represented by Embaloh (Maloh), was unclear until the end of the last centrury. The Dutch linguist K.A. Adelaar showed that they are especially close to Buginese and thus can be included in the South Sulawesi subgroup.
Position within Austronesian
At the current stage of research, the South Sulawesi languages are considered to make up a primary branch of the Malayo-Polynesian subgroup within the Austronesian language family.
South Sulawesi influence in Malagasy
Adelaar (1995) suggested that Malagasy vocabulary does not solely derive from Barito, but also contains many words that are of South Sulawesi origin. Further evidence was presented by Blench (2018).
Proto-South Sulawesi has been reconstructed by Mills (1975).
