Balantak is an
Austronesian language spoken at the head of the eastern peninsula of
Sulawesi. It is classified as a member of the
Saluan-Banggai branch of the
Celebic subgroup. The Balantak language is the primary language of the Balantak people. Although 90% of the population are also proficient in
Indonesian, the vernacular is still vigorously used in everyday contexts, and most children only speak Balantak before entering school.[2]
