The title `As Baile` can be translated as `away from home`.
The song itself is all intonation, although you might say the intonation is `based` in Irish Gaelic. Enya sings `or?, horo, mo-ray he u way, he u way` and so on. The word `or?` is an interjection that could be translated as `oh!` or `oho!`, but the rest of the song is intonation.
