#Dark might be the first German speaking TV series I've watched and I'm already picking up some German words (some of which stood out bcos I've sang them plenty of times through #AOT OSTs lol):
Schicksal: Fate
Aber: But
Ich bin: I am
Jahr: Year
Wer bist du: Who are you
Verspreche: Promise (hands down MY FAVOURITE bcos of how ridiculous it is to pronounce)
Was: What
Wann: When
Apparatus: Apparat
Also I've always assumed Herr and Frau were Male and Female teachers respectively, just bcos in my high school those who took Mandarin as their third language called their teachers, Laoshi (teacher) while those who studied Japanese called their teachers, Sensei (also teacher). I've always thought the others learning German calling their teachers Herr (Name) and Frau (Name) essentially meant teachers as well. Bcos of this show, I know it's not haha.
