Wow. 473 is very specific--Is it derived from corpus linguistics analysis? (or fun hyperbole :) ?)
Oh, I should probably mention my sources; I simply compared the number of search results on a search engine :) Probably not a reliable figure, but it might tell you that it's not a very common word. It's mostly used in formal texts.
It would be correct but trips are more like vacations, road trips, traveling. "alle Nordmenn liker å dra på turer"
"every Norwegian person likes to go on walks" wasn't accepted? In British English going "on" walks is correct? Also, is there a substantive for Norwegian? Like as in, a Swede or a Dane? Thanks!
Yes, "going on walks," "going for walks" and "going walking" are all commonly used.
I believe "Every Norwegian [person] likes to..." would be "Hver Nordmann liker å..."
I hope that helps. :0)
