It is my intention in this paper to present the similarities and the differences of the standard Yoruba language and the Egbd dialect through lexical processes, phrasal categories and syntactic processes. The work will follow the generative grammar approach as | Chomsky's (1981) Government and Binding theory, and will substantially utilize exiting grammars and example to give up comparable structures in Egbd dialect for the possible long term exercise in historical linguistics. Today, words in Yoruba metalanguage are rich and adequate because dialects fill possible gaps. This work will partially show the source of the terms coined by the linguistics. In addition, historical Yoruba linguistics will benefit from this study when other dialects would have been surveyed and documented. The monolingual method of approach, the Ibadan four hundred word lists was used in collecting my data and some references were made to some books and articles available on the languages.
