As language learner and hobby linguist - the easiest way to learn a language is to actually familiarise yourself with it as much as possible.
Read dovahzul, listen to dovahzul - sadly there aint much avalaiable yet but it helps.

Use Dovahzul as much as possible - a very effective way to learn a language is by using it. If you want to go for the extreme take a dictionary along and try to speak only in Dovahzul for some days, using the dictionary every time if you dont know a word.

However i recommend doing grammatical studies first cause unlike real living languages there wont be native speakers correcting your grammar for you

If you haven't given the Memrise course a try yet, I'd recommend it. There will be new courses soon but this one should work for now. I find practice also really helps, whether that's writing, joining an RP in the forums, or dropping by the community chat every now and then.

I'd recommend focusing on a few words at a time, using them as much as you can. In my opinion, knowing a few words really well is much more important than vaguely knowing many words. The language can be helpful here because it tends to be short and oversimplified, so a few words can carry you a long way.

Play Labyrinthian game, do the canon-noncanon memrise course, use the translator for words, and keep trying to remember, that's how I'm learning.

Thanks, guys. I'm trying both of these, and they're really helpful!
