Fer language
The Fer language, also Dam Fer or Fertit, one of several languages called Kara, is a Central Sudanic language spoken by some five thousand people in the northern Central African Republic near the Sudanese and Chadian borders, in the region known as Dar Runga.
While the Ethnologue leaves it unclassified, it appears to be a Bongo–Bagirmi language within the Central Sudanic family ; Roger Blench classifies "Fer" as Bagirmi, but "Kara of Birao" as one of the related Kara languages.
