I'm having lots of fun playing "spot the loanwords"! It seems like German and French have the most popping up, but I've spotted a lot of Italian loanwords in cities/architecture and a few Turkish ones in weapons/warfare.
It's kran in Russian, Belarusian, Ukrainian, and Bulgarian, too. Strange, since Dutch is a Germanic language but all the others are Slavic.
Duolingo ignores punctuation, including hyphens (-), so it reads life-goal as two separate words. I agree with you that "one life goal" is a strange construction. "Life's goal" implies the main goal in someone's life, but it's automatically "one" so the word "one" wouldn't be used.
