The issues in focus constructions in Yoruba language have generated lots of arguments among Yoruba scholars. Some of these scholars are of the opinion that focus constructions are noun phrases. The other scholars claim that focus constructions are derived sentences which express a complete statement. Another area of debate among Yoruba scholars is the numbers of the focus marker in the dialects of Yoruba, especially, Èkìtì dialect, and that whether the anaphoric ó is a subject resumptive pronoun or preverb. In this paper, we examine and contribute to the various arguments on these two topics.
