The interrogative intonation in the Kunigami dialect of Okinoerabu, Ryukyu

Abstract Cross-linguistically, intonation patterns for yes/no questions rise in many languages. However, there are multiple reports of interrogative sentences with falling intonation in Japanese dialects. It is said that five types of interrogative intonation exist in Japanese dialects: rising, where the end of the sentence always rises; falling 1, where the end of the sentence always falls; falling 2, where the interrogative appears morphologically in the sentence, and the sentence falls; complement, where tone in the sentence falls if the interrogative morphologically appears and rises if it does not; and gradual rise, where the tone gradually rises until the end of the sentence. However, the Kunigami dialect does not adhere to these patterns. In Kunigami yes/no questions, the tone falls if an interrogative morphologically appears but reveals a distinctive intonation from a declarative sentence if it does not. Therefore, in the case of Kunigami, the interrogative intonation typology should not be reconstructed on the basis of absolute rise or fall but on the basis of contrast with a declarative sentence.
