Hyman and Mchombo (1992), Babye (1985), (Myers 1987), (Rice 2000), and Hyman (2002 & 2003) have shown that there is affix ordering in Proto-Bantu languages that obeys the 'CARP' (Causative-Applicative-Reciprocal-Passive template). Drawing data from Lubukusu, a Bantu language, the current study analyzes affix ordering of class-changing morphemes, arguing against the templatic morphology that most researchers have shown to be dominant in Bantu languages. The current study uses Bybee’s (1985) principle of iconicity (principle of relevance), where it is proposed that affixes closer to the verb stem are more 'relevant' to the verb than to the rest of the sentence and those affixes further away are less relevant. Based on Baybee’s relevance principle, the study argues that there are various affix ordering orders in Lubukusu, which are semantically motivated. The data that are used in the analyses are self-generated and verified by three native Lubukusu speakers who are competent in the language. Findings show that as much as Lubukusu obeys the templatic morphology, the same is violated in various morpho-semantic contexts. The study recommends more studies on affix ordering in the Lubukusu language based on other existing frameworks that have been tested on languages rather than those from the proto Bantu family.
