Wrong translation for “å kunne” - it is not “to know” - should be “to be able to/ can”. Will this be corrected?
The original creator of this course has the memrise name “shamiim”, but they don’t seem to be a member @of this forum.
If you want to change entries to this course and the original course creator has moved on and no longer wishes to curate it, then you could ask @MemriseSupport or @Lien (I hope this is the memrise member of staff I was thinking of) to ask if you can be made a course contributor, which means you would be able to access the course database and make any changes you think are necessary.
While “to know” is translated to “å vite” most of the time, you can use “å kunne” to mean “to know” in some cases, like…
“Jeg kan gangetabellen utenat.” (I know the table of multiplication by heart)
“Jeg kan hele historien.” (I know the whole story)
It’s a way to express that you’re possessing certain information or knowledge. In the examples above, you actually cannot use “å vite” (maybe the second example, but not without paraphrasing).
But you’re absolutely right it means “å vite” most of the time and should be translated as such.

Hi Amanda. Thank you for the information. I’m not sure how to contact “shamiim” so I’ll try the contacts you suggested.
Thanks!
With any luck, they will reply here directly in this thread, now that I have tagged them. At least that is how it has worked before.
