Thanks to @silmeth.mstdn.social.ap.brid.gy for the assistance on getting to the bottom of this

The Wiktionary references will be updated soon to reflect this

And Cleasby and Vigfusson are authoritative on the Old Norse meaning, suggesting that this is indeed the most likely etymology

Seems like MacBain might have been a source of information here, at least regarding the Scottish Gaelic cognate

This 2014 paper is likely the uncredited source of information for the 2021 Wiktionary edit. It's the only published research I could find on this word's etymology. The information seems reasonable enough, though no historical form is yet attested. But we have the Scottish Gaelic cognate “isbean”.

Congratulations!

I noticed that in the interpretive editions of inscriptions, where certain interpreted markings seem to be using digital characters that are not currently rendering for me on my phone, such as the i in maqi, and the c in mucoi, in the screenshot example.

The most useful definition, it seems, lies in the diatopic distribution of isoglosses within a group of lects that share a common diachronic ancestry. Within such a spectrum, a dialect may be understood as the geographic convergence of isoglosses.

Since there are no precise, quantifiable parameters to determine where a dialect ends and a language begins, I have always found the concept of “dialect” to be somewhat imprecise.

This article looks at the history and development of Old Irish grammars: the pre-Thurneysian past, Thurneysen's Grammar of Old Irish and its central position in current Celtic Studies, and what future grammars will look like.

If you already have a Discord account, or are willing to create one, the best places to practice Irish, learn dialects, and access resources are these two places:

discord.gg/craiclegaeilge

discord.gg/u7F5yR7g

I'd be happy to discuss things in more detail there as I'm not on Blue Sky as much

This is generally true with the various dialects, but especially in Munster which tends to have much weaker Gaeltacht regions than the other provinces, though Kerry Irish is still relatively strong in the area.

The only place you'll generally find Déise Irish today is in the Waterford Gaeltacht regions. And even then, the dialectal features have been fading with each generation over the last few decades. The youngest speakers today might have a few Déise Irish features, but not to the same extent as before

There are plenty of resources, but not really anything at a beginner level if you're only starting out. In fact, Munster Irish doesn't tend to have the best beginner resources compared to the other dialects, but there is plenty written about the Munster dialects, both living and dead.

The Irish language in that region of Tipperary when it was spoken would have indeed been part of the Déise dialect. South Tipperary Irish had some interesting features, but it was essentially Déise Irish in general. The last speakers in the region died out in the 1960s.

Sure! Happy to help however I can.

I'm very intrigued! Can you share or link to any information about this new database?
