The short answer is: no, there isn’t.
In the Irish language, we have three main dialects:
Those are provinces in Ireland. The fourth is Leinster. It’s along the east coast of Ireland. It’s where Dublin is located, the capital city of Ireland.
There are Irish speakers in Leinster, for sure. However, the local native language died out there quite a few years ago.
Our motto here is: learn Irish first, worry about specializing in a dialect later.
