For a long time I've wanted an artificial language that was deliberately unambiguous. At times I even felt the urge to try to create it myself, but other obsessions also demand their time.
Then I, entirely by chance, found out about Lojban. An international vocabulary, no exceptions, no irregularities, no ambiguity, no homophones, no polysemy, no possibility for puns. It's everything I want in a language. Even allophones bother me in natural languages, and Lojban makes every reasonable effort to minimize them.
What do you think of Lojban?
