I did learn some Arabic using Duolingo and during duqsi days as a kid but I don't think I need it unless I plan to live in the Arab world which I don't rn so what language is most beneficial to learn I tried ABIT of Portuguese and it was quite easy to understand but outside of that language I haven't learned anything else besides ABIT of Spanish during high school days and I'm in my twenties now so it's been a while since I studied that.
