Kitharaka Segmental Morphophonology With Special Reference to the Noun and the Verb

Abstract

In this thesis we explore Kitharaka segmental mophophonology using the Natural Generative Phonology model as proposed by Hooper (1976). We have looked at the underlying representation and the surface realisations of consonants and vowels and critically examined the processes that link the two levels. Furthermore, we have discussed in detail the rules that underlie and govern these processes. We have shown that these rules include Ganda law, Dahl's law hormoganic nasal assimilation, nasal palatalisation, continuant hardening, nasal devoicing, gliding, vowel harmony, vowel heightening, vowel deletion and vowel coalescence. Rule formulations are presented in words as well as in formal representations. The phonological distinctive features used for the rule formalisation are based on the Chomsky and Hall (1968) system of features. Besides examining segments in native Kitharaka words we have also analysed the behaviour of segments in vocabulary borrowed into Kitharaka from Kiswahili and English. We have shown that, although there is room for limited variations, these segments adjust into Kitharaka sound system in a fairly systematic and consistent manner. Furthermore, it has been shown these adjustments involve consonant and vowel substitutions and insertions.
