Omotic languages
The Omotic languages are a branch of the Afroasiatic family spoken in southwestern Ethiopia. The Ge'ez script is used to write some Omotic languages, the Latin alphabet some others. They are fairly agglutinative and have complex tonal systems (see Bench language, for example).
Languages
The North and South Omotic branches ("Nomotic" and "Somotic") are universally recognized. The primary debate is over the placement of the Mao languages. Bender (2000) classifies Omotic languages as follows:
South Omotic / Aroid (Hamer-Banna, Aari, Dime, Karo)
North Omotic / Non-Aroid
Mao
Bambassi
West Mao (Hozo, Seze, Ganza)
Dizoid (Dizi, Sheko, Nayi)
Gonga–Gimojan
Gonga/Kefoid (Boro, Anfillo, Kafa, Shekkacho)
