A major finding of this study is that while ‘má ’ is attested as a negative marker in SY, it is attested as a progressive marker in ẸD. It is also found that, the negative marker ‘kò’ is the only negative marker in SY that has variants ‘kò’ and ‘ò ’; but all negative markers in ẸD, except ‘à ì’ and ‘tì’ have variants. In terms of behaviour and features of these negative markers in different syntactic positions, a lot of differences exist between those that are attested in SY and ẸD, bringing about differences in their negative constructions. The paper concluded that, despite the fact that Ẹ̀gbá is a dialect of Yorù bá , a lot of differences were seen in their negative constructions as a result of the differences in the syntactic positions and features of the negative markers attested in the two speech forms.enNegative ConstructionsStandard YorùbáẸ̀gbá DialectArticle
