I'm not too sure what the combining form of "Slovenian" would be in Irish. My stab at the correct form is An Cumann Cairdis Slóivéini-Cheiltaigh on the basis of an Cumann Ibeirni-Cheilteach "the Iberno-Celtic Society".

I feel like I should post here.
As you can see from my siggy, I'm currently learning Welsh. That's all well and good, but I don't think it would be a good plan for me to try to learn the other Celtic languages because I think I'd just get all mixed up in very short order. It's not really that I don't want to, but I've heard enough bad things about knowing two closely related languages that I'm discouraged from it. As well, getting my head around VSO word order, "she's after throwing rain", dialect differences in tag questions, etc. and trying to keep my English and French straight at the same time has been enough of a struggle that I'd rather not make it any worse.

Irish and Welsh are so different, I personally've had no problem with learning both at the same time. It interesting, seeing the similarities though!

Come to think of it, if I tried to learn Irish and Welsh, or whatever, at the same time, I'd probably just stop due to inability to multitask, never mind the danger of coming up with some degree of Wirish whenever I tried to use either language. In any case, I'm pretty sure that if I tried to tackle Irish right now I would end up calquing it on Welsh if I didn't try really hard to think of them separately. I will always have to remember that not everyone has an yn, for example; I always want to stick yn in stuff no matter what language it may be. (*I'm yn making coffee.) I never stopped finding it strange that in Welsh you have an yn in both Maen nhw'n fawr and Maen nhw'n ysgrifennu but in Scottish Gaelic (and probably Irish is similar) you have Tha iad mor and Tha iad a' sgriobhadh, and *Tha iad a' mor doesn't work just as *Maen nhw fawr doesn't. Apparently SG doesn't have any word serving the function of yn + soft mutation.

Tha mi nam shaor
Be.PRS 1S in.my carpenter

In this construction, "carpenter" (saor) is lenited.

Only trouble is I can't figure out what it means. "I am in my carpenter"? What's serving the function of yn, would you say?

ann "in". Wouldn't you?

Sure. I still can't figure out what it means, though. "I am a carpenter", maybe?

That's exactly what it means.

In central and southern Irish, this sort of construction contrasts with a simple Is saor mé "I am an artisan[*]" and emphasises that the state is temporally bounded in some way, i.e. "I am an artisan now; previously I was just an apprentice." But in Ulster Irish and Scottish Gaelic, this is simply the unmarked way of identifying your profession.


[*] "Carpenter" is siúinéir or saor crainn "artisan of wood".
