The Idaasha speak Ede Idaasha, a Yoruba dialect which contains loan words from the neighboring Fon. There are no major variations within the Idaasha dialects, except for the distinction between the phonemes [C] / [TCH] or [TS] as in Idàáchà (The people), Acha (Culture), Ichu (Yam), and Ochu (Month); more common among some more remote segments of the population as against [SH] like in Idaasha, Asha, Ishu and Oshu more common in the major urban centres. Besides Ede Idaasha, Standard Yoruba (SY) is used as a form of 'High Speech' in a form of dialectal diglossia where Ede Idaasha occupies the familiar/nuclear arrangement and SY occupies more formal functions such as Churches (communion, bible studies, prayers, sermons Etc), Mosques, Training programmes and Formal education. Most people understand SY but it isn't the preferred dialectal form spoken or employed in everyday interaction.
