Irish differentiates between the 2nd person singular (tú) and the 2nd person plural (sibh). While this distinction has been lost in "standard English", it still exists in many dialects (you all, youse, yiz, ye, etc), and is helpful for some learners to remember that they have to use different term in Irish.
1.Am I guessing correctly that madraí is not eclipsed after the possessive adjective ár because it is plural?
2.Am I also correct in guessing that plural nouns are not lenited after prepositions, i.e. ag na buachaillí? I have read through the Tips & Notes but do not seem to see any instructions re plurals in above situations. May be I have missed them. I would appreciate some advice, please.
- The possessive form ár triggers eclipses, not lenition, and ‘m’ is not affected by eclipsis, that’s ‘madraí’ stays the same.
- That’s correct. Full explanation here: https://en.wikipedia.org/wiki/Irish_declension#Articles
