I'm just wondering if it's possible to add a new language in the list. The thing is that there're a couple of songs on this site (for example, this one - https://lyricstranslate.com/ru/tamara-obrovac-touca-la-louna-lyrics.html) that are performed in the Istriot language. For lack of such an option, they've been submitted under "Istroromanian" which has nothing to do with Istriot except for the fact that they're spoken in the same region and that they both belong to the romance languages family.
P.S Oh, no, I'm so sorry. There is actually such a language in the list. Anyway, then I have another question: is it possible to add "Istroromanian" instead? The thing is that when I change the language of the site to Russian, "Istriot" is translated as "Istroromanian". When I switch it back, the things are the way you already know.
In short, is it possible to add "Istroromanian" in the language list and arrange for the proper translation of Istriot and Istroromanian into other languages?
