Bukusu dialect
Bukusu is a dialect of the Masaba language spoken by the Bukusu tribe of the Luhya people of western Kenya. It is one of several ethnically Luhya dialects; however, it is more closely related to the Gisu dialect of Masaaba in eastern Uganda (and to the other Luhya dialect of Tachoni) than it is to other languages spoken by the Luhya.
Phonology
Several consonants undergo fortition after nasal consonants: [β, w → b, j → dʒ, l, r → d]; Mutonyi (2000) postulates that Bukusu has no phonemic voiced plosives.
Variations
The language has three main variations:
The dialect spoken north of Kimilili area, with its heaviest influence being noted in the region around Kitale
The dialect spoken west of Webuye town, with its purest form being in the region around, and to the west of, Bungoma
The dialect spoken east of Webuye town, extending into Kakamega and Lugari districts.
Of these, the language spoken around Kitale town is usually considered the purest form - this is because the other two dialects are significantly influenced by other dialects of the Luhya languages.
