"Den er min."

Translation: It is mine.

[Weird_Ed]

What is the difference between "det" and "den".

[fsmatthew]

I know this is quite late but, hopefully, it helps someone else who is stuck with this. I believe that "Det" is used for neuter nouns or for things where the gender is unknown and "Den" is used for masculine/feminine things.

So would, "Det er mitt" be proper if the thing that is "mine" has an unknown gender? I'm really confused by this subject.

[mad1974]

Could you also say "Den er mi?" since "den" is m/f?

[cifarec]

Does this imply that the subject is necessarily masculine? Or is masculine the default if the gender is undetermined?

[Sondrec]

It implies that the subject is singular and masculine or feminine.
