I know this might be a strange description but for me personally I think at times it sounds like a conglomoration of what I've heard spoken in Russian, French, and Italian. The Polish language is uniquely beautiful though -in my opinion.
I learned some last summer. It was really hard because of the case system, pronunciation, and mostly spelling. I still remember a bit, I think it was like Dziewczcynka or something. It'll take a lot of dedication.
Oh yeah. That turned me off right at the bat. I saw that word and I went "nope!" Then again, some other languages that I want to learn have really long words too (German, anyone?), so I guess I'll just have to deal.
