Further to Aodh's question about orthography. I was interested to see a transcription of a version of Áirdí Chuain clalled 'Ceol Daibhí', collected around 1830. "dá mbeinn" (if I would be) written as "Dam beinn" and "go mbeadh" written as "gom beadh".
It amuses me to think of a bilingual pun if the line in the Our Father - "go dtaga do riocht" (your kingdom come)- were written "god taga do riocht".
