Other comments: Mbula-Bwazaa is spoken by approximately 100,000 speakers in
Adamawa state: Demsa, Girei, Numan, Shelleng, and Song LGAs, Nigeria.

Mbula-Bwazaa seems use a rare known counting system based on thirty: mon=1, a mon=30 (1 times 30); rap=2; a rap= 60 (2 times 30);  taru=3, a taru=90 (3 times 30). Makes me curious how the sequence goes. further studies are needed to verify the "big numbers." The people have difficulties producing these big numbers because they are hardly using them. English (or Hausa) is much easier and more direct. Mbula-Bwazaa is tonal language. Updated data in phonemic or phonetic transcriptions with tones needed.
