That doesn't mean that all of the words in Réilthíní Óir are only found in West Munster. You are making wild statements without proof. I am categorically not saying that your conclusion is false, but rather that it remains to be shown. The "proof" you've offered here would be insufficient in a PhD viva voce.

I will not do your research for you. Good luck!

I'm afraid, a Ghuirt a' Lín, that use of spellings like gh in Seanachló are just wrong. Seanachló used the dot for lenition: ġ. Irish people are typically contemptuous of their own heritage, for some reason.

Caiġdeán

The use of the punctum delens to indicate lenition is a shorthand. In the pre-digital media era it saved ink and it saved effort to use the dot instead of an "h" to indicate lenition. In the current case, it would take considerable effort to change all the lenited letters in the excerpt from using the "h" to using the punctum delens.

It's not shorthand; just wrong. There really is no point to the Gaelic Revival if people can't be bothered to respect the culture. It would not take any effort at all to use the correct letters. I have a keyboard set up on my computer to type fluently in seanachló.

The Irish Revival has always been dominated by L2 learners in Dublin who had no time for the real language, as Peadar Ua Laoghaire pointed out.

It's like saying Czech š is a shorthand for sh. No, it isn't.

Thanks for sharing this interesting article.

There's more to the story of caighdeán.

Fr Clune notes in the foreword to his book Réilthíní Óir that most of the terminology in the book came from the islands off of County Kerry.

Tomás Ó Criomhthain relates in An t-Oileánach of Fr Clune spending nearly two months of eight hour days with Tomás gathering information for Réilthíní Óir. Tomás notes that this was the most grueling time of his life...

I haven't seen the latest version of Tomás' book now called An tOileánach but it's reported that it now includes Tomás' gripe about not being mentioned in Réilthíní Óir.

It's true that Fr Clune thanked others for helping with his book in its foreword but he only makes an oblique reference to the isles off of Kerry and he doesn't mention Tomás at all.
