Translation:The Viking snuggles under the duvet, when it is cold at night.
Historically, danish vikings were famous not only for their raids but for their snuggles as well
I simply thought because it refers to the weather rather than the Viking himself.
Because it says "det" in the Danish sentence. If it would say "han", he would be appropriate.
What the heck is a duvet? I'm a native speaker, with three college degrees (one which qualifies me to teach English) and this is the first time I've ever heard the word duvet. Looking it up in a dictionary it is evidently some kind of a quilt. If that is what it means then the word 'quilt' should be accepted as 'duvet' sounds absolutely bizarre. Duvet is probably a common word in some places, but in others it's completely unknown.
Then Oxford is wrong, it is also used in the US. I may be wrong, but I think duvet actually refers to the thing that you put a comforter into. I assume it is orginally a French word, but I'm just guessing.
Yeah I'd never heard of them until I went to college. It's like a comforter.
