- Bori languages
- Goni languages
Proto-Borogoni had some thirteen noun cases, grouped into two groups with different stem forms: śarib (water), śarib-i, śareb-a, etc. The major modern languages have little trace left of this declension system; Filofonecian retains the two stems (ośriw/ośraw), but nothing else.
The noun also had three numbers: singular, plural, and numeric. This is preserved in Goni but lost in Bori, which has just singular and plural.
