Ryukjin Language - Tumblr Posts
I found this leed, a likely sway on Koryo-Mar. One thing's for sure, it's distinct & is almost only spoken among the elder lines/generations Jaegaseung people (whose heritage language is lost) & Jaejung dongpo (ethnic Koreans in my southern neighbour's country) plus about 1 in 10 of Koryo Saram (from ex-Soviet countries including from my northern & western neighbours & excluding Sakhalin Koreans, who instead speak from one based off a landspeech/dialect from southern parts [Jeolla & Gyeongsang] of South Korea despite writing by North Korean standard). Not quite the same thing as the Hamgyong landspeech, but it's closer to Korean than is Jejuan, even though neither are really mutually understandable with Korean landspeeches or especially the North or South standard leeds. Apparently, a wordbook (dictionary) bestands/exists between Korean & Yukjin, but do feel free to show us any such works on it that do.
Was gonna look for bits of the Ryukjin language or the lost language of the Jaegaseung, but this is an interesting discussion of languages in diasporic settings (outside the original homelands). Use in media can be dicey especially in cases like inside, but at least efforts were made in the cases of Manchu.
While I've not found much more about them yet (as much as I'd like to), inside are some bits & key differences I've so far found regarding them in relation to the Korean majority & the Jurchen origins in general. May well be a continuous presence through much of the history, but I do hope the diasporas abroad can rediscover themselves even whilst living among the surrounding dongpo (maybe alongside the Jejuan people) either way.
