Historical reanalysis in the Nakijin dialect noun accentuation system

A comparative analysis of the Nakijin dialect (Northern Okinawa) and the Amami dialect (Tokunoshima Island) reveals that while most Ryukyuan dialects are tonal, Nakijin is an accentual language where pitch interacts with vowel lengthening. This study reconstructs the prosodic system for underived nouns in Proto-Northern Ryukyuan, demonstrating how the Nakijin dialect's unique accent developed through historical reanalysis. By examining phonological patterns and comparing them to other Ryukyuan dialects, researchers identified a shift from tonal contrasts to an accentual system with high-pitched accents in specific environments.
