I'm five skills away from finishing the skill tree, yet I find that there is more vocabulary in a French 1 textbook I'm using than there is on Duolingo. Is it possible for you guys to add more complex vocabulary onto Duolingo, or even for users to suggest words/phrases?
Hi, I have been using Memrise in conjunction with Duolingo to learn more words. You might want to check that out, until the vocabulary is expanded here also.
There's a duolingo course on memrise too: http://www.memrise.com/course/61965/duolingo-french/
I think there used to be a vocab section and they're talking about bringing it back. I think it's a good idea. I've learnt a lot of new vocab by doing immersion too.
There has been some mentions of expanding the existing trees (I can't remember whether it was on here or in interviews with Luis), but no definite published plans for this, as far as I know. I guess the focus right now is on publishing new courses.
