Halò, a h-uile duine
I'm learning gaelic, I've encountered a grammartical problem while I was watching this video
I was studying the gaelic text, I saw the sentence "Bha esan a’ cur roth ùr air a’ bhaidhsagail."
I've figured out that the word baidhsagal is masculine and genitive, but the problem is, shouldn't it be dative after the preposition air?
Or could air require both dative and genitive?
What's the difference between dative and genitive here?
