Balanta languages
Balanta (or Balant) is a group of two closely related Bak languages of West Africa spoken by the Balanta people. Description
Balanta is now generally divided into two distinct languages: Balanta-Kentohe and Balanta-Ganja. Balanta-Kentohe
The Balanta-Kentohe (Kəntɔhɛ) language is spoken by about 423,000 people on the north central and central coast of Guinea-Bissau (where as of 2006 it is spoken by about 397,000 people, many of whom can be found in the Oio Region) as well as in the Gambia. Films and portions of the Bible have been produced in Balanta-Kentohe. The Kəntɔhɛ dialect is spoken in the north, while the Fora dialect is spoken in the south. Ethnologue lists the alternative names of Balanta-Kentohe as Alante, Balanda, Balant, Balanta, Balante, Ballante, Belante, Brassa, Bulanda, Frase, Fora, Kantohe (Kentohe, Queuthoe), Naga and Mane. The Naga, Mane and Kantohe dialects may be separate languages. Balanta-Ganja
Balanta-Ganja is spoken by 86,000 people (as of 2006) in the southwest corner of and the south of Senegal. Literacy is less than 1% for Balanta-Ganja. In September 2000, Balanta-Ganja was granted the status of a national language in Senegal, and as of then can now be taught in elementary school.
