Metathesis in the Austronesian language Leti, is not only regular and

productive, but may be driven by purely phonological considerations.

This paper examines two types of metathesis in Leti, the first being

motivated by a requirement that all phrases end in a vowel, and the

second, by syllable well-formedness conditions: syllables have onsets

and tautosyllabic consonant clusters are avoided. Drawing on recent

work in Correspondence Theory, a unified account of the Leti facts is

obtained through the subordination of the constraint Linearity to syllable

structure and phrasal alignment constraints. Further, it is argued that

violations of Linearity are evaluated in a gradient manner. Additional

constraints are also motivated as a means of accounting for the

observation that it is consistently the final vowel and consonant of a

given morpheme that metathesize, even though metathesis involving

other segments would result in equally well-formed Leti words. A

comparison of this CT account with a rule-based account of metathesis

is also included.
