Why are nouns spelled differently in different sentences. For instance, sometimes they add an H (mairteoil, mhairteoil) remove a vowel (Do, D')
Please read the section introductions for lenition and possession.
Mo vs M' and Do vs D' are contractions before vowels.
Anyone else think of David O'Doherty reading this one?
I put mo 'chuid' mairteoil as I felt the implication was not all the beef is mine. Shurley shome mistake boss?
That's not really what cuid means, and even if it did, the piece of beef on your plate is indeed all yours.
But it would be mo chuid mairteola, not mo chuid mairteoil.
