Connacht Irish is also spoken in the Meath Gealtacht Ráth Chairn and Baile Ghib.

The dialects of Irish in Connacht are extremely diverse, with the pronunciation, forms and lexicon being different even within each county.

Lexical and pronunciation differences exist within Mayo with Tourmakeady featuring an "í" sound in vowel endings much more commonly.

In addition to this the lexicon of Dún Chaocháin to the east of Belmullet tends to be far more Ulster influenced than that of Eachléim (murlas vs ronnach) and there is a huge Ulster influence on the dialect of North Mayo in general owing to historic migration.

The Irish of Eachréidh na Gaillimhe and Dúiche Sheoigheach tend to share more phonetic commonalities with neighbouring Mayo than with South Connemara Documented sub-dialects include those of Cois Fharraige[a] and Conamara Theas,[b] both of which are in Galway, and Erris in Mayo.
