@robert_wolniak@101010.pl I learned it a bit, but it was only working while I did it together with my siblings – having people to talk/write to seems really crucial for language learning, at least for me. Now I am barely able to slap together a sentence, and even that only because it's such a simple language.

If you are into that I would also recommend playing some of the games that randomly have an Esperanto translation, e.g. Slay the Spire.
