I enjoy learning languages, and I often find that things are clearer to me when I compare them to Esperanto, than when I compare them to English. What are some language-learning resources that use Esperanto as the language of instruction? I'm most interested in Russian and Spanish, but suggestions for other languages are welcome as well.
Here one can learn Toki Pona through Esperanto: http://tokipona.info/
There are several conversation guides from national languages to learn Esperanto, and it's able to use most of the content in both directions. For instance, I have these:
- [Italian] Parlo esperanto: manuale di conversazione (Davide Astori, 1996)
- [Catalan] Guia de conversa català-esperanto: breu introducció a la llengua i al moviment (Pedro M. Martín Burutxaga, 2016)
You said you're interested in Russian. Here's a link to learn Russian idioms through Esperanto: http://www.russievirtuelle.com/locutions/index.htm
ГОЛОДНЫЙ КАК ВОЛК
[golodnij kak volk]
Malsata kiel lupo.
Esti tre malsatega.
Malsata kiel lupo (hundo).
Vi diris, ke vi ŝatus lerni la Rusan. Jen ligilo por lerni rusajn idiomaĵojn per Esperanto.
On Telegram, there's over 20 bilingual groups (Esperanto + another language) which were originally intended for beginners to learn Esperanto, but many experienced Esperanto speakers also use them to ask questions in Esperanto about their target language, so it sometimes feels like a group tandem chat. I personally have used the Esperanto-Svenska group to ask questions about Swedish and received very helpful explanations. You can find the complete list of Esperanto Telegram groups on telegramo.org.
A good article about this is http://blogs.transparent.com/esperanto/language-learning-through-esperanto/ One resource listed there that no one's pointed out yet is the Chinese site http://esperanto.cri.cn/everydaychinese/index.htm
On Italki or similar platforms, you can search people with a solid Esperanto knowledge and ask them to teach you a language per Esperanto.
Duolingo has a Spanish->Esperanto Tree which you can use as a reverse tree to gain familiarity with Spanish if you know Esperanto. While it may be more common to use a reverse tree after using a forward tree to your target language, you can always combine a reverse tree with other resources or switch back and forth between the English->Spanish and Spanish->Esperanto trees.
I’m constructing an Esperanto-hosted Encyclopedia Dictionary of Mercan English. I link to mostly English-language resources, but also to the Esperanto version of Wiktionary, and I often make comments, in Esperanto, about points in English. You can access the dictionary here: http://enciklopedia-vortaro-de-la-merk-angla.weebly.com/
You can learn the basics of Japanese with the book Enkonduko en la japanan of Yamasaki Seikô. You can buy it at UEA's Library.
