Why are "ag an gcóisir" and "ag an chóisir" both correct solutions?
In Ulster Irish, lenition is used rather than eclipsis.
makes sense, thanks!
Always?
In the “preposition an noun” case where the other dialects would eclipse the noun, yes, Ulster Irish always lenites the noun instead.
Ok, good to know. Thanks.
I gcónaí.
Sorry, force of habit.
