Fundamento de Esperanto
Hello, everyone! Saluton!
I'm not sure if this has been shared before, but if anyone's interested in reading the original "Fundamento de Esperanto" (which includes a grammar section and a multi-lingual dictionary), you can find it here: http://akademio-de-esperanto.org/fundamento/index.html
Keep in mind that later additions to the fundamentals of the language are not included here - even Zamenhof's way of creating new words with apostrophes in between the affixes is rather odd to modern eyes, but I think it could be a good way of visualizing each prefix or suffix more clearly, thus helping memorization.
Bonŝancon kun via lernado!
