Lubukusu, a Bantu language spoken in Western Kenya, like majority of African languages, is a tone language. The tone languages use various rule-governed tone levels that dictate their functional load on the lexicon as well as in the languages’ grammar. This paper attempts to understand tone by providing a description of its representation in Lubukusu verbal system. Data was collected from the Bukusu-English word list compiled by Marlo, Sifuna and Wasike (2008). All the data collected was subjected to verification by Lubukusu native speakers. The description shows that Lubukusu has both shifting high tone and spreading high tone within the verb from the same high tone sponsor. The data also reveals a case of shifting and spreading of a high tone leftwards interestingly from different high tone sponsors.
