While traditionally held to be a branch of the Kaili-Pamona languages,[3][4] they share many features with languages of the Seko branch of the South Sulawesi languages[2] and have been reclassified in recent sugrouping proposals as South Sulawesi languages that were strongly influenced by Kaili-Pamona languages.[5][6]
