"Is it a familiar girl?"
Translation:Er det en velkendt pige?
I wrote "Er den en velkendt pige?" but the correct answer has "det". I'm still confused on why this sentence would use "det" instead of "den". I thought that since you're talking about a girl, you would use den. What am I missing?
Det is used "as the subject of være/blive when the verb is followed by a noun, a pronoun or an adjective, irrespective of gender or number."
They do the same thing in German with "Das ist ein Mann", "Ist das eine Frau?" etc.
