You want to learn this beautiful conlang but are at a loss of how to start? Fear not, Eana Mokri will guide you! :P
The most effective way to learn and practice is to join our community, of course, via http://forum.learnnavi.org and especially http://discord.me/learnnavi. But even without joining you can learn the language:
Step 1: Leave your excuses why you can’t learn behind, roll up your sleeves and get to work!
Step 4: Use the language actively as soon as possible. Read, write, chat, translate back and forth, but most importantly, speak and listen as often as you can. That way you will automatically learn new vocabulary as you go. For this looking up unknown words is very useful, for example by using http://dict-navi.com.
These and more learning methods were discussed in Eana Mokri’s episode #5.
Step 5: Repeat step 1, 3 and 4 – and keep going!
