@pierogiburo Esperanto is an artificial language, similar to Elvish or Klingon, and it’s not ‘European’ at the very least. I don’t see Latin - it’s a dead language, it’s not a ‘mother tongue’ of any European ethnicity, but if Esperanto is valid, Latin should also be valid, because it is European. I also don’t see Romani, often referred to as Gypsy, and other dialects that are languages in their own right.
