Probably not. It’s a good word, but it’s firstly mostly used in writing in Swedish and not as much in everyday conversation and also the course teaches elementary Swedish, and that word belongs to a whole other level. But I’m sure it’s being mentioned in the forum if learners want to pick it up.

I thought it was in there already. If not, I hope it gets added soon! ^_^

I think it would be nice if "hen" would appear in tips and notes, even if just shortly. Duolingo seems to have quite open-minded community, so I think it would be helpful :)

This is my biggest problem with duoLingo!
