Rotuman phonology is characterized by a complex system of rules involving the morphologically-conditioned metathesis of word-final vowels with the immediately preceding consonant, as well as umlauting, vowel shortening, and diphthongization, which apply disjunctively to the output of the metathesis rule. This paper shows that Autosegmental Phonoly provides a simpler account of these rules than previous descriptions. Positing Rotuman to have separate vowel and consonant tiers, this analysis shows that Rotuman phonology has a rule of V-truncation at the level of the CV skeleton, which triggers the leftward reassociation of the orphaned feature matrix to the preceding V-slot. The resulting double associations are resolved with the help of a series of disjunctive rules that refer to the featural conflicts between the two vocalic segments associated to the same V-slot. This account is superior to other accounts because of its simplicity and of the fact that it captures the anticipatory nature of what is traditionally described as metathesis.
