Your cant be Sein From what i learned from DL "Your" can have 3 translations:
dein/deine/... : when you talk to one person in an informal way
euer/ eure/ ... : when you talk to more than one person in an informal way
ihr/ihre/... : when you are talking formally ( respective your )
I haven't seen the word "Gegner" in Duolingo before, so I was puzzled when I heard it, in a sense I didn't know have I heard it well, should I really write that down, it wasn't used before, what if I heard it wrong etc. Is this something I should report to Duolingo? I mean, new words shouldn't be in the hear-to-type-afterwards sessions before one actually learns there is such a word. Now I know it is, no problem there now, but confused me a lot first.
