Esperanto is a gateway drug to other languages...
It makes me want to learn every Romance language ever, lol.
Agreed. Even though Esperanto is a made up language, I feel it's all romance languages combined into one. To me, it sounds like Spanish and at times German.
It sounds like a little Spanish + European Portuguese + Romanian + a touch of French + a dash of Russian + a tiny bit of German + something else.
Then there was this epic reddit comment: http://www.reddit.com/r/duolingo/comments/2j08zw/esperanto_the_duolingo_gateway_drug/cl7ae5i
Tute. Mi lernas la hispanan kaj la germanan, kaj ankaŭ la ukrainan, ĉion pro mia laboro kun Esperanto. Efektiva droga!
I don't know Esperanto (and probably I won't study it), but I've always liked the Romance languages... all of them! They are beautiful!
