Lojban language resources – Language Links Database
Lojban – is a constructed, syntactically unambiguous human language based on predicate logic, succeeding the project of Loglan. The name “Lojban” is a compound formed from loj and ban, which are short forms of logji (logic) and bangu (language). Development of the language began in 1987 by The Logical Language Group (LLG), who intended to realize Loglan’s purposes as well as further complement the language by making it more usable, and freely available (as indicated by its official full English name “Lojban: a realization of Loglan”).
