Would most native speakers be able to tell the difference in pronunciation between nuachtan and nuachtain?
I think there's supposed to be a slight difference between the broad and slender vowel pronunciation respectively, but I can't hear it. It might be the audio sample, or it might just be my lack of fluency.
I really couldn't tell if the final "n" in nuachtáin was slender or broad either...
In my opinion, the final 'n' in 'nuachtáin' sounds broad.
Why is "An dteastaionn" used here?
Because it's a question. an is used to mark questions, and it causes eclipse of the following verb.
Is "Do you want" acceptable here?
"Do you want" no, "Do we want" yes.
Would "an bhfuil" and "An dteastaíonn" be interchangeable in this instance? I got it right, but want to see if my understanding is correct.
In day to day conversation, yes, they would be interchangeable.
Im still lost as to where uainn and afew other words were taught and why there aren't any hints to them when needed.
