"Is it yours?"
Translation:Er det jeres?
Am I wrong in thinking that det must go with dit and den must go with din?
Not in this sentence, I guess.
Here the "det" addresses "er" while the pronoun "din" is referred to an object that we don't know. Each of them (det and din) has his own gender. They are not correlated.
So if we would have "hus" as object, the sentence would be: "Er det dit hus?"
If we have"tallerken" as object, it would be: "Er det din tallerken"
This is a guess, but someone with better knowledge than me can confirm!
It depends on what you are reffering to. Din for common (n-words), and dit for neuter (t-words)
In a question like this, where the subject it unidentified (in this case: "it") how do you know when to use din, det, or dine?
They do. Instead of clicking start on your lesson, click the lightbulb and you'll find it.
