"We have seven kinds."

Translation: Vi har sju sorter.

[HeatherSha938036]

Are type and sort interchangeable?

I know that this course is in Bokmål, but why aren't syv and tyv accepted as 7 and 20, respectively?

[Deliciae]

"Syv" is accepted, for anything but listening exercises.

"Tyve" is not, as it's not listed as an acceptable alternative to "tjue" in the dictionary anymore.

[fveldig]

'tyve' is accepted in Riksmål, a more conservative form of Bokmål.

It seems 'tyve' and 'tredve' was accepted in Bokmål 2003-2005, and 'syv' still remains. You could probably used them without trouble in Norway, but as there is a strive to use the correct forms as often as possible in this course, they shouldn't be accepted.
