Towards a unified theory of morphological productivity in the Bantu languages: A corpus analysis of nominalization patterns in Swahili

Models arguing for a connection between morphological productivity and relative morpheme frequency have focused on languages with relatively low average morpheme to word ratios. Typologically synthetic languages like Swahili which have relatively high average morpheme to word ratios present a challenge for such models. This study investigates the process of agentive nominalization from the perspective of the Dual Route Model. The findings suggest that all agentive nominal forms should decompose when accessed and thus that speakers of Swahili should include these morphemes in their lexical inventory apart from root morphemes. This process appears to not be influence by noun classification, or verbal derivation.
