Very good point! And it gives you a real sense of community too, connecting with other users to find the answers to questions. In this regard it is far better than something like, say, Rosetta Stone. And a lot cheaper, and to be honest, a lot more effective in helping you progress quickly.
There are problems with all learning systems. This is proving to be one of the best.
No, I don't. But it appears that we are both wrong a bit. Glaoigh is first conjugation, because it is one-syllable verb (according to Basics 2). And it is told also here:
So, armed with this knowledge, we must admit that the stem is glao-, not glaoi-. The role of i letter in glaoigh is to soften the gh so it is glued to it and then should disappear with gh, so at last we come to that that glao- is the stem and in conjugation needs only adding -nn.
That's how I see it.
OK, at last I have found it:
An Dara Réimhiú - Na Rialacha. They seem to say you were right - 2nd conjugation. But this one is an exception to 2nd conjugation because of one-syllable-ness...
Yes, ar does mean “on.” The reason why ar is in this sentence is because of the nature of the verb glaoigh. In English, for this meaning of “call”, “call” is not a phrasal verb — just “call” is needed to express the act of calling. In Irish, glaoigh ar is a phrasal verb — it needs the ar to express that same act of calling, much as English has its own phrasal verbs such as “call for”, which has a different meaning than plain “call”. Thus, rather than use the literal translation of “You call your father” as in English, Irish uses the literal translation of “You call on your father”.
