Pronunciation-wise, what's the difference in how you pronounce "oirthear" vs "iarthar"? I went to teanglann.ie to have a listen, and unfortunately, they only have the pronunciation of "oirthear", but not "irthear". So I went to forvo. It sounds to my ears that "oirthear" in the munster pronunciation (on teanglann) sounds the same as "irthear" (although the connemara and ulster pronunciations of "oirthear" sound different.) But then, I'm not sure if all the forvo pronunciations are good or not. Can anyone help with this, so I can tell my "iarthar" from my "oirthear"?
What I'm getting is that I think "iarthar" is sort of like "ear her", whereas "oirthear" is more like "air her."
