*Lojban's grammar is simpler than of most natural languages, but complex in its own unique way. Lojban is an experiment in thought, as well: its users aim to see how its unique language structures affect thought and understanding.
*Lojban's grammar is based on simple rules, and its linguistic features are inspired by predicate logic. <!--There is no distinction between nouns, verbs, and adjectives; rather, Lojban sentences are held up by ''relations'' (like “… gives … to …”) and the ''arguments'' satisfying them.-->
*Lojban allows the expression of tiny nuances in emotion, using words called [[attitudinals]], which are essentially spoken emoticons.
*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.
*Lojban allows you to communicate concisely without unnecessary or undesired details. For example, you don't have to always think of what tense (past, present or future) to use in a verb when it's already clear from context.
*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, which allows potential new explorations in the fields of artificial intelligence and machine translation.
*Lojban is machine parsable, so the syntactic structure and validity of a sentence is unambiguous, and can be analyzed using computer tools.
<!--*Lojban is unambiguous in syntax. Natural languages often have ambiguous sentences — does "He's left" mean that he's still here or that he's gone? Lojban systematically eliminates this.-->

What is Lojban?

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.

Lojban means different things to different people

  • a linguistic curiosity - a test-bed for language experimentation
  • a challenging way to expand their minds or discipline their thoughts
  • a new perspective on languages
  • an entertaining medium to communicate with friends or create art
  • a domain for exploring the intersection of human language and software
