Outside of Poland is there a reason to learn Polish,,probably not??
In Chicago it could be helpful, not anywhere else in the US or the rest of the world for that matter. Why would anybody want to learn a language that you will never use unless you move to Poland? If I were to do that, I would be studying for months beforehand out of respect.
Are you referring to people who aren't
from Poland, but are of Polish origin (like me), or people who aren't?
If it's the former, I totally disagree - there's plenty of places (in Europe, at least) where Polish is useful. I've found it an incredibly useful language, and if I had children, there is absolutely no doubt that they would be taught to speak Polish, whether my partner was Polish or not (hopefully not, lol :D ).
If, however, you meant the latter, then I totally agree - particularly if you're planning on moving there or to go on holiday there, and like to do as I do when going abroad (learn a language out of respect/curiosity, etc).
