Should "air" not be replaced with "oirre" here as Mòrag is a female name? :)
No because Morag is the subject, not "her" as oirre would be. If there was no name then yes, it would be oirre.
I thought the same thing. Still don't quite understand "air."
So I'm guessing that ''oirre'' would be considered a pronoun and ''air'' used instead in the case all nouns? Like ''Tha an t-eagal air mathair'' ?
