"dóibh" is "for them"? I thought '-ibh' always meant second person plural. This is getting almost as confusing as eclipsis and lenition.
Yes. dóibh is "for/to them" daoibh is second person plural. And, really, it all just takes practice. You'll ger the hang of it.
This is pretty tricky, and it caught me by surprise, too. I looked at a chart and saw there are only two cases to beware of: 1) "díobh" means of/from them and 2) dóibh means to/for them.
Otherwise, the -ibh suffix always indicates 2nd person plural. And except for the two examples just discussed, a -u, -ú, or -eo suffix indicates the 3rd person plural.
I was not used to "an beile" . It sounded like "baylee". I didn't even get the verb right but I did get "mhathair" right and that is a definite improvement for me since I have never been able to get that word especially when it has the extra h.
Maith thú! You are correct that the word is pronounced like "baylee" which is the nominative plural form. Since the definite article is "an" instead of "na" it appears that the dialect of the speaker is apathetic to the final vowel being a short "e" instead of a "long i" sound. Or else the speaker made a mistake.
On some progs broadcast from Donegal, I typically hear "daoine" pronounced like dee-nee. So there may be some of that influencing. Someday I'm going to get into the book Speaking Irish and start studying the dialect differences in more detail. Hope to God that they survive else the country will be that much poorer when they get standardized.
As I pointed out in the links in my answer, the Ulster pronunciation of béile is the same as in Connacht and Munster, and the current Duolingo speaker doesn't have any problem pronouncing béile in other exercises. She knows how to do it right, she just screwed up in this exercise, reading out the plural béilí after the singular an.
Again no sound... but only for one sentence in each series of exercises...
Might be a server problem. I discovered that waiting up to a minute has gotten the audio in several exercises. I'm in Future Tense 2 currently where this is happening. Could be hacking by a competing language course LOL.
