skyblueteapot yes there are, the’s a “world Esperanto Association” (UEA, Universala Esperanto-asocio) and you can take their exams and they give you a certificate. I have a friend who just passed the C1 exam, he took it at the annual Spanish Congress of Esperanto, so you can take them once every year or when they announce someone from the UEA can go to your country to do those exams. Those are the same ones (the UEA people, the academy) that update the dictionaries with the new words that come up, to keep up with the times.
Michele pointed me to this thread with regards to getting the lernu dictionary integrated with LingQ since I was able to do so with a Latin-Italian dictionary earlier.
Well, the good news is you can indeed!
If you want to see the very raw response for a definition you can use the following url:
where WORDTOSEARCH is the Esperanto word you want to search, obviously, and TARGETLANGUAGE is the target language code, for example, to English, put EN, Spanish, ES, Italian IT, etc
So for example, to find out what “bela” means in German, use
If you want something that more closely resembles their dictionaries UI I can probably whip something up over the weekend; of course, since the response is returned in plain text, LingQ could probably also choose to parse it and include it in the sidebar where babylon usually goes if they wish.
