Modern #Icelandic is another Nordic vernacular that would be much easier to understand for Scandinavians if it weren’t so innovative(!) in its phonology and puristic in its new derived vocabulary. Also this is often misrepresented in stating that “strange Scandinavian dialect X” must be mutually comprehensible with Icelandic because both sound “old” (read rather “strange”).
Yet, unlike #Närpesiska, and unlike any ”Dialect X” except #Övdalian, Icelandic is indeed very archaic in morphology.

@elmerot Many refer to it as #Elfdalian in English. So cool to have the association with ”elfs” even if it is coincidental (”älv” meaning ’river’ in Swedish).
#Övdalian is based on the name of the language in the language itself: ”Övdalsk”
Actually it is also now recorded by both names by SIL, even mentioning “Elfdalian” first: https://iso639-3.sil.org/code/ovd

@elmerot In the picture, which is from 2017, I put it as an offshoot during the #umlaut era, that is sixth century CE. I use its official English name #Övdalian. In that case it would be older than East Norse. Now, that may be too early, if we can explain forms like ”singa” ’to sing’ (Swedish ”sjunga”, Old Icelandic ”syngva”) as a later innovation. That will be one of my blog topics.

My blogs will feature some elements from my existing research, This includes #umlaut, including the spread of #rounding, and #breaking.
#EastNorse and #Gutnish, perhaps #Övdalian, have a different story to tell here and may contribute a lot to the reconstruction of how the process originally proceeded.
