I'll be honest from the get-go. I am NOT a fan of Tolkien, and would prefer if we keep his Elvish out of it. I don't know why, but it doesn't strike me as being very ordinary or something. I think it's my general dislike of stereotypical high fantasy. So, lately I've been thinking that I'd really like to learn to speak and type in Na'vi. Several months ago, I found the linked website, which I thought was pretty great. Only recently did I realise that there's actually guides (some are parts of incomplete series') on there for download that will teach you the grammar and syntax of Na'vi. What I find extremely interesting is the syntax. Paul Frommer, the creator of Na'vi, really outdid himself, I think. A few examples follow. That's two mostly related sections. What I'm wondering is whether any of you have taken the time to learn fictional, or, rather, constructed, languages (Tolkien's English aside) fluently? Particular examples (others found on this Wiki article) are Na'vi from James Cameron's Avatar, Nadsat from Anthony Burgess's A Clockwork Orange, or even Loglan and Lojban, the logical languages. Discussion commence.
