It's an interesting philosophical question. I certainly think Professor Tolkien made an effort to simulate real languages when he invented the Elvish languages. However, I would be hard pressed to consider something a real language without a community of speakers, something Quenya and Sindarin lack compared to, say, Esperanto. It's only possible to communicate in Elvish if you are very selective in your topic. As much as I love Elvish, I wouldn't consider it to be "real" in the normal sense of the world.

yes of course, a language should have a community speakers, maybe you should comment this in the page, that could help our page, more vital, thank you sir Paul
