Rapa Nui: A Case for Correspondence in Reduplication

This squib argues for the role of correspondence in reduplication by examining the vowel length alternations in Rapa Nui reduplication. The analysis shows that vowel shortening in the base after reduplication is due to the enforcement of vowel length identity through Base-Reduplicant correspondence, while the motivation of vowel shortening is problematic for theories without surface-to-surface correspondence. The findings suggest that reduplication-phonology interactions cannot be handled solely by serialism or cyclicity, and a parallel Optimality Theory evaluation with BR correspondence is supported.
