News: 20 July 2006|#20July2006 - Have you visited the land where Lojban is spoken? It's called samxarmuj, meaning "computerized imaginary universe". It's a text-based world on the internet, where you can operate a character using commands in either English or Lojban: the online software is bilingual. Lojban is like the language of magic in samxarmuj-- speaking it can bring objects into existence and give them form and function.

You don't even need a plane ticket. Just click here and use the password "moo" to log in as a guest until you have your own account. Commands are typed in the bottom-most part of the window. Guest accounts are limited to using English, so type the "register" command to get your own account. It's totally free.

More information, including other ways to access samxarmuj, is available at the wiki page about The Lojban MOO.

What Is Lojban?

Lojban is a carefully constructed spoken language designed in the hope of removing a large portion of the ambiguity from human communication. It was made well-known by a Scientific American article and references in both science fiction and computer publications. Lojban has been built over five decades by dozens of workers and hundreds of supporters.

While there are many artificial languages, Lojban has a number of features which make it unique:

• Lojban is designed to be used by people in communication with each other, and possibly in the future with computers.
• Lojban is designed to be culturally neutral.
• Lojban grammar is based on the principles of logic.
• Lojban has an unambiguous grammar.
• Lojban has phonetic spelling, and unambiguous resolution of sounds into words.
• Lojban is simple compared to natural languages; it is easy to learn.
• Lojban's 1300 root words can be easily combined to form a vocabulary of millions of words.
• Lojban is regular; the rules of the language are without exception.
• Lojban attempts to remove restrictions on creative and clear thought and communication.
• Lojban has a variety of uses, ranging from the creative to the scientific, from the theoretical to the practical.

This site is the official repository of materials from The Logical Language Group (the LLG), the non-profit corporation which has led Lojban development since 1987.

As part of the LLG's commitment to the community, this site attempts to reflect a cross section of the Lojban community outside of the LLG. Fortunately, there are too many Lojban sites for the webmaster to keep track of, and so occasionally a site is overlooked.

This means that there are links here that point to other sites. Many of these sites contain material not sanctioned by the LLG. In fact, some of the material on this site isn't officially sanctioned, but we'll make it clear what is and is not official LLG material.
