I'm sorry, but I just don't get it. I'd say I'm pretty interested in languages but as English is not my native language I guess I forgot most of the grammatical technical terms that don't map to the German ones I kinda remember.

I think some example sentences (with translations) at the start would go a long way (Not 6 different ones, just some.. explanation of the currently shown one). Maybe it would also help if you fixated the example sentence (e.g. via css) so it's visible while scrolling. I don't speak Turkish, so I suppose I'm bad at remembering the whole sentence while scrolling down and reading the rest (not so much a problem for the first paragraph)

So I see how this could be cool to play around, I lack a bit of motivation as I don't understand the differences, and maybe a translation that changes (or not!) with the users' settings would help. Might also be that I'm tired and currently surrounded by people speaking Spanish and my mind isn't able to focus on yet another language ;)
