Sumbwa language
Sumbwa is a Bantu language spoken in northwestern Tanzania.
The language is mainly spoken in Bukombe, Mbogwe and Geita districts ; Kahama district ; Biharamulo district and Urambo district – Tabora Region. Given the 2002 Census figures and population increases since then, the number of Sisumbwa speakers may be estimated as follows: Bukombe: 137,115; Kahama: 100,377; Geita: 79,490; Biharamulo: 4,306; Ilemela: 85; Kishapu: 110; Kwimba: 152; Misungwi: 103; Nzega: 358; Shinyanga : 2,260; Urambo: 36,755; This estimation gives 361,111 Sisumbwa speakers. These are the figures recorded in the Tanzania Language Atlas, and this puts the language at no. 25 out of the 150 Tanzanian languages identified.
Sumbwa is still largely undescribed as there is an old grammar, a trilingual dictionary and description of some components of the morphology.
