Morphophonological realisation on inflected verbal roots with initial vowel sounds in Sepedi

Abstract

AbstractIn instances where verbs that start with vowel sounds and a vowel prefix is attached, the hiatus is repaired through resyllabification, i.e. the manifestation of an initial underlying sound called a glottal catch. This sound fills the onset position of vowel initial verbs in Sepedi, and is responsible for the drastic alternation when the verb comes into contact with a reflexive prefix or an object concord. This article examines the effect of morphophonological realisation on inflected verbal roots with initial vowel sounds in Sepedi. The data collected through documents and semi-structured interviews shows that the glottal catch makes verbs follow the CV syllable pattern. The vowel reflexive prefix which threatens to create a hiatus is repaired through epenthesis by adding a sound to the interior of a word (at the beginning of prosthesis). This repair strategy ensures that the CV syllable structure of Sepedi is maintained. This article provides new data that offers innovative understanding of Sepedi on the concepts such as epenthesis and hiatus, relating to alternations in morphophonological environments using the optimality theory.
