Ganza language

Ganza, also known as Ganzo or Koma, is an Omotic language of the Afro-Asiatic family spoken in the Al Kurumik District of the Blue Nile (state) in Sudan and in the western Benishangul-Gumuz region of Ethiopia, specifically in the village districts of Penishuba and Yabeldigis.

It also goes by the names Ganzo, Gwami, Koma, and Koma-Ganza.

Phonology
Ganza does not utilize consonant length phonemically.

Although vowel length is typically contrastive in Omotic languages, Ganza does not have a clear contrast between long and short vowel phonemes. Instead, Ganza has predictable utterance-final vowel lengthening and a set of monosyllabic words with double vowels.
