Well, that's me watched the last couple of episodes of Ros na Rún, so I'll be down to just the two a week from here on in. I noticed another instance of "le" (with) appearing when the subtitles said something in English using the past for a situation continuing to the present (you know, "I've been living here for five years", "I haven't done that in ages" etc) so I rewound to try to hear what verb construction they used. I couldn't make it out. I'm going to focus my conscious studies on the verb system for the time being -- it's the thing that I seem to have most trouble with.
Right, there's a documentary about the harmonica on the TG4 site, so I'm off to watch that now.
