My understanding is that Irish orthography is different, but highly consistent. So once you overcome the initial hurdle of understanding how different phonemes are pronounced, you're mostly good to go. I tend to think of the Irish alphabet as similar to but subtly distinct from the English alphabet: the two languages use the same Latin characters, but have different sounds associated with them.
