• Úsáideann muid an cailín.
• Úsáidimid an cailín.
I see both forms are accepted now - great.
why not, Usaidimid an gcailin?
Why not "an chailín"? Aren't feminine nouns lenited after "an" nominative?
"Cailín" is masculine.
Oh? Alrighty, thanks.
To elaborate on this, it's because of the diminutive ending -ín. When it is added to a word, the word becomes masculine (it's a neat trick you can use if you're having trouble!). Also, note that cailín literally means "little maid" (caille + -ín)
