Other comments: Bolgo or Bolgo nii, Bólɡònî is spoken by approximately 1,800 speakers in Guéra region: Bahr Signaka department, Melfi subprefecture, Bon and Ibir villages; Salamat region: west border area, Chad. Bolgo has recorded traditional numerals from 1 to 10 years ago, not sure if they are still using traditional decimal system or vigesimal system of numbers after ten or now use Chadian Arabic numerals after ten. New data for numbers after ten with tone marks is required.
