As a native of Pandora, I can assure you that Na’vi isn’t all that hard to learn. Any language is learnable. It just takes dedication. Look at me. I learned English after my trip to Earth in a matter of weeks. Fluently within months. And now? Well now I’m the greatest extraterrestrial blogger on Earth.
I jest, of course. Arianna Huffington is a much better blogger than I. Though in my defense, she’s had a lot more time to learn the language of your planet. If you one day wish to be the greatest alien blogger on Pandora, you can go to LearnNavi.org to learn our beautiful language. Maybe we’ll even throw in a few curse words.
