Linowan
The books pretty much always say "Linowan" but I have often wondered if the nation itself is Linowa and the people Linowan or if they must ALWAYS be referred to as "Linowan" whether you mean the place or the people. I tend to say "Linowa" if I am referring to the nation, and "Linowan" if I am referring to the language or people. The accuracy of my approach remains questionable, however.
