Vowel/Glide Alternation in a Theory of Constraint Interaction 

First Published in 1997. The alternation between high vowels and glides is shown here to follow from the interaction of phonological constraints as defined by Prince and Smolensky”s (1993) Optimality Theory. The alternation stems from simultaneously comparing moraic and nonmoraic parses of high vowels for constraint satisfaction
