This dissertation deals with the possibility of having syllable final consonants, including geminate consonants, and the interaction of such consonants with syllable weight and vowel length, by means of the moraic tier. The goal of this work is to have the range of patterns of consonant occurrence and vowel length follow from simple patterns in simple interactions. Predictions about possible phonological patterns are made via the interaction of simple constraints in Optimality Theory. Extensive treatments of over-filled (hypercharacterized) syllables, appendix consonants and gemination are provided.
