Beauty in the artifice : an introduction to Lojban by Ewa
Lojban is a carefully constructed spoken language. It has been built for over 50 years by dozens of workers and hundreds of supporters.
Lojban's grammar is based on simple rules, and its linguistic features are inspired by predicate logic.
Lojban allows the expression of nuances in emotion using words called attitudinals, which are like spoken emoticons. ue marks that you're surprised; ba'u marks that you're exaggerating.
You can be as vague or detailed as you like when speaking lojban. For example, specifying tense (past, present or future) or number (singular or plural) is optional when they're clear from context.
Lojban is machine parsable, so the syntactic structure and validity of a sentence is unambiguous, and can be analyzed using computer tools.
There is a live community of speakers expanding the lojban vocabulary day by day.
