Lojban

A constructed language by The Logical Language Group.

Claudio Gnoli writes, "A revised version of Loglan, with mainly lexical changes, began by a group of loglanists disagreeing with Cooke Brown's way of managing it. A fixed grammar, written by John Cowan, has been published in 1997. LLG has several active members, who are in contact via a mailing list, some of which, like Jorge Llambias and Nick Nicholas, are able to speak current Lojban. All this makes Lojban to be the main reference language for today's loglangers.""Lojban has a whole array of emotional indicators, with optional intensity indicators as well, expressing about 80 significant emotions. These can also be subdivided as physical, social, emotional, intellectual, sexual, or spiritual varieties. AFAIK, Lojban has the richest facility for emotional expression of any known conlang, which is rather ironic for a 'logical language' (but moving the emotional expressiveness out of thelogic-based core makes sense in its own way)." - John Cowan

Language sources: Root words based on the six most widely spoken languages; grammar based on first-order predicate logic. It has 1350 root words, hundreds of particles and thousands of compound words.

Predicate Logic, consistency. The original idea was to create an artificial language with which to test the Sapir-Whorf hypothesis.
