If someone's English isn't perfect, he might be confused because you have "everyday" (which is an adjective) under "gach lá," when I think you mean "every day."
So does this mean that, similar to English, one could say "tagann... ar ais" OR "fillim" and "come back"/"return" are pretty much interchangeable?
Are all the end "r"s pronounced like a really short "t" sound. Now that I am trying to say every sentence I am finding I can't say a lot of them :( To me this sounded like "Tagim na bay dit ash gawk law"
The "r" sound in Irish is like the "dd" in the word "buddy" in American English and corresponds to the same single "r" sound found in Portuguese and Spanish. The IPA symbol for it is [ɾ], and it is called an alveolar flap. The only difference is that, as rev._mother said, it is slenderized, so it has a slight English "y" sound quality to it (in IPA, it would be a [j] quality).
