"Is it traditional?"

Translation: Er det traditionelt?

[GreatDane7]

What is the difference between ending the word with "elle" and ending it with "elt"?

[DRaupe]

Why can't you say: det instead of den?

[rasmuscph]

You can. But remember it would be "Er den traditionel?" without the t in the end.

[CongChen2]

Why can you say "er det min?" then?
