When is math used and when is mhath used?
Check the Tips section of these lessons, it says there that math is used for male nouns (like feasgar) and mhath for female nouns (like oidhche and madainn) :)
mhath seems connected to morning, while math is afternoon or evening... in my understanding :)
Is there no vocative case after the dative or prepositional phrase? No downvotes necessary.
