Ongamo, or Ngas, is a probably extinct Eastern Nilotic language of Tanzania. It is closely related to the Maa languages, but more distantly than they are to each other. Ongamo has 60% of lexical similarity with Maasai, Samburu, and Camus. Speakers have shifted to Chagga, a dominant regional Bantu language. History An expansion of Ngasa speakers onto the plains north of Mount Kilimanjaro occurred in the 12th century. The language was mutually intelligible with Proto-Maasai during that period. Vocabulary retention from this time attests to the cultivation of sorghum and elusine by the Ngas. Subsequent immigration of Bantu-speaking Chagga over the next five centuries considerably reduced the extent and viability of the Ngasa language.
