Sumbwa language

Sumbwa (or Sisumbwa/Lusumbwa) is a Bantu language spoken in northwestern Tanzania.

The language is mainly spoken in Bukombe, Mbogwe and Geita districts (Geita Region); Kahama district (Shinyanga Region); Biharamulo district (Kagera Region) and Urambo district (Uyowa) – 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 (R): 2,260; Urambo: 36,755; This estimation gives 361,111 Sisumbwa speakers. These are the figures recorded in the Tanzania Language Atlas (2009:3), 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 (Capus 1898), a trilingual dictionary (Kahigi 2008a) and description of some components of the morphology (Kahigi 2005; Kahigi 2008b).
