I've done some searching on this topic and I can't find anything as this is a topic I think that a search engine can parse very well. I was reading The Irish of Chois Fhairrge, Co. Galway and the author mentions that the person they interviewed had very little English and I was wondering what the accent in English of a person whose only language was Irish (regardless of dialect) up until say their late teens would sound like. I'm fairly certain that English is so entrenched in Ireland and for so long that it's unlikely it would be exactly that of a person who was raised as a "heritage speaker" of Irish would have in English. A heritage speaker being a type of native speaker who is introduced to the "dominant language" at a young age thus making their original native language become somewhat of a second language for them.
http://en.wikipedia.org/wiki/Heritage_l ... _languages Note it does not imply how good anyone's command of the heritage language would be but simply states that when the person comes into contact with the "dominant language" (English in this case) that the dominant language is what they use in school and in the majority of interactions out side the home.
Back on topic, I was then watching
this episode of Comhrá and the gentleman being interviewed mentioned he didn't speak much English at the time and it reminded me of this question.
So does anyone know if there is a recording of a monoglot native Irish speaker learning English as an adult?
