High Quality Content by WIKIPEDIA articles! Connacht Irish is the dialect of the Irish language spoken in the province of Connacht. Gaeltacht regions in Connacht are found in Counties Mayo (notably Tourmakeady, Achill Island and Erris) and Galway (notably in parts of Connemara and on the Aran Islands). The Mayo and Galway varieties differ from each other in a variety of ways, as Mayo is geographically between Galway and Donegal, so Mayo Irish has a number of features in common with Donegal that Galway does not have.
