Phonological and Morphological Influences on Vowel Hiatus Resolution in Rutooro

When the morphology of a language creates instances of successive vowels, these cases of vowel hiatus are often resolved or repaired. This paper presents a wide variety of instances where vowel hiatus is created within verbs in Rutooro, a Ugandan Bantu language. It is shown that five different strategies are employed to resolve vowel hiatus: deletion, gliding, diphthongisation, epenthesis, and lexical allomorphy. While some of these processes are largely phonological, there are a number of morphological factors which also play a role in determining which of the various strategies are employed. All of these are explored and discussed.
