until now i don not know when to use der or den.not clear to me
Change der to den if the masculine noun is receiving an action (it is the direct object).
Why does "den Lehrer" translate to "the teacher" rather than "the teacherS", as we've learned in previous lessons?
why is Sehen sie Der Lehrer is wrong?
"Sehen sie der Lehrer" sounds like a question to me in German.
Ja. Doesn't the verb usually go first when asking a question? That's what you did ohnopandaho.
Why does it even say "Sie essen den Lehrer". Seems demonic and chthonic
