Hi all, I am a bit rusty on my Gaeilge, but I would have translated the lyrics slightly differently.

In the 2nd verse where he says he will go "a deanamh leanna", I suggest it means he intends to go woo-ing, make love or make an offer of marriage. I think this also fits with the rest of the verse better where he refers to items that would be offered in marriage such as bedclothes, etc.
