Abstract:

The grammatical derivation of languages varies, leading to language specificity. In particular, languages with noun classes have unique methods of realizing them through prefixing and sometimes suffixing, such as in the Bàtọ̀nu language. This study focuses on the interface between syntax and phonology in the grammatical realization of the noun class system in the Bàtọ̀nu language, spoken in the Baruteen Local Government Area of Kwara State in Nigeria. Interviews were conducted to gather data, supplemented by secondary sources. Theoretical principles from Government and Binding Theory (GB) and Autosegmental Phonology were used to represent sentence structure and the tonal analysis of the data. Previous research established that the language has seven noun class markers (NCM). We found that phonological features, such as labialization, nasalization, and tone, can influence and determine the grammatical functions of class markers in languages that attest to them. In the case of Bàtọ́nu NCM, the tone is the determining factor. We assume that the class markers are unmarked at the underlying representaion (UR), and when a floating high tone (HT) is assigned to the NCM underlyingly, they function as class markers. When a floating mid-tone (MT) is assigned, they become relative clause marker variants, and when in contact with the HT focus morpheme -á in focus constructions in the language, they function as focus marker variants.
