this is missin 'a' which according to the precious question is needed?
The /Fhi/ combination makes a vowel sound, so the vocative particle "a" is not needed.
this "Fhionnlaigh" sounds like "yewl lie" - dreadful pronunciation. I don't know how ANYONE can get this one!
It's not a "dreadful pronunciation" - that's just how you to pronounce it.
