Attention is principally paid to the phonological processes operating in the dialect such as assimilation, insertion, nasalization and coalescence. These phonological phenomena are accounted for within the framework of Autosegmental Phonology. This theory is employed to analyze some abstractable features of Yagba, which ASP is designed for. This is what segmental phonology is unable to account for. In the light of this, this work further found out that any feature that is abstractable is better handled using ASP as these features are better represented on separate tiers. The universal left-to-right application of ASP rules is echoed in this study. The data obtained for the study were generated through the Ibadan 400 wordlist of basic items as well as a designed frame technique. In view of the analysis presented in this study, it is recommended that subsequent researches on Yagba phonological structure should be researched into namely, vowel harmony, tone and other areas not covered in this study, using this study as a reference material.enautosegmentaltierswell-formedness conditionabstractable featuresuprasegmentsArticle
