The morpho-phonological status of uku- in isiNdebele

This article looks at the constructions in (Zimbabwean) isiNdebele with the formative uku-. Nguni linguistic studies have classified uku-constructions in Noun class 15. There is an uku-infinitive formative that has been identified and used in the characterisation of infinitive verbs. There is a conjunctive uku-that should be noticed as a distinct formative in Nguni. When all uku-forms have been identified, the article points out, it should then be possible to observe the morpho-phonological properties of each and to establish a linguistic criterion for Class 15, and the separation of the infinitive from the Class 15 uku-. The assigning of noun or verb to the uku-forms can then become a routine and regular academic exercise with consistent interpretation of the form(s).
