Issues on the Categorial Status of ‘Òun’ in Yorùbá

This paper examines issues on the categorial status of oun in Yoruba grammar, particularly its status as conjunction. It draws insight from binding theory to show that in Standard Yoruba and other related dialects, such as Ilaje?, oun is constantly anaphorically bound by the first of the two nominal constituents it purportedly coordinates in line with binding rule and binding principle ‘B’ within the particular phrasal context where it is often analysed as conjunction. Relying on data from South-Eastern Yoruba dialects (O?do and Ao) and a Central Yoruba dialect (Omuo-Araro?mi) where there is clear cut evidence for two oun in the lexicon, one of which is non-referential unlike the oun in Standard Yoruba, the paper shows that the use of oun as conjunction in Ao, reported in Taiwo (2005), is not exclusive as there are other dialects in the language that do the same. The paper however provide additional evidence to demonstrate that the claim that oun is a conjunction in Yoruba based on the Ao data cannot be generalized to Standard Yoruba and other related dialects (e.g., Ilaje?) where the non-referential oun found in Ao, Omuo-Araro?mi, and O?do dialects is absent. These make argument in favour of the so-called conjunction oun in Standard Yoruba (School) grammar being a a3sg pronominal anaphor compelling.
