yeah, it would be like this (copied from somewhere on the internet) : In German, there is a difference between 'being familiar with someone or something' (kennen) and 'knowing something (like a fact)' (wissen). The original implied that they were familiar with nothing whereas I assume you meant something closer to the original GoT saying "You know nothing, Jon Snow".
So, du weißt nichts, AmjadKalan.
Excellent question. For “You always study, but you learn nothing.”, you could either make the first verb phrase progressive, as in „Du bist immer am Studieren, lernst aber nichts.“; or you could make the second one perfective, as in „Du lernst immer, aber erlernst nichts.“; or, better yet, do both: „Du bist immer am Studieren, aber erlernst nichts.“.
The distinction in German between ‚lernen‘ and ‚studieren‘ is not generally the same as that in English between “to learn” and “to study”.
The German verb ‚studieren‘ is only used to mean “to study” in the sense of “to be a university student”, as in „Du studierst Philosophie.“ = “You're majoring in philosophy.”; or in the sense of “to scrutinize”, as in „Du studierst die Antworten.“ = “You're studying the answers.”.
The German verb ‚lernen’ is used both to mean “to learn“, in the sense of “to gain knowledge”, as in „Du lernst die Antworten.“ = “You're learning the answers.”; and “to study”, in the sense of “to work at learning”, as in „Du lernst für die Prüfung.“ = “You're studying for the test.”. .
that's why I said I believe it is because I wasn't sure. I'm not a native german speaker I'm just learning :-) I had just never seen lernen as study, that's why I thought it might be that :-) But I do know in English "You study Nothing" wouldn't be a complete sentence. Thanks for the info about Studieren! I guess both could work then since we don't know the context if they are talking about school wise or general wise.
nichts is a pronoun and basically goes where a noun phrase would go.
Ich kann den Hund sehen. "I can see the dog."
Ich kann nichts sehen. "I can't see anything. I can see nothing."
Wir haben gestern zusammen Mathe gelernt. "We learned/studied mathematics together yesterday."
Wir haben gestern zusammen nichts gelernt. "We didn't learn anything together yesterday. We learned nothing together yesterday."
