loglang

From Lojban
Revision as of 05:17, 10 May 2020 by Mediator64 (talk | contribs) (Laadan is a feminist language, and therefore is not only inspired by "logical principles". I do not know which order it should appear in, which may be problematic. It also seems strange that Loglan and Nalgol are not under the "Loglan family".)

loglang - a constructed language recognizably based on logical principles.

a language in which every utterance is traceable to a unique representation in a suitable logic formalism, which representation correctly gives the meaning of the utterance, and is reached from the linguistic form by automatic formal rules (parsing).

John Clifford

Alternatively, the term loglang is used to describe a language that belongs to the Loglan family.

Loglangs based on logical principles only

Languages in Loglan family

Others (in historical order)

  • Loglan is now a generic term that refers both to James Cooke Brown's Loglan, and all languages descended from it. Since the organization that Dr. Brown established, The Loglan Institute (TLI), still calls its language Loglan, it is necessary to state that this section refers specifically to the TLI language, instead of the entire family of languages.
  • Nalgol, which was a project of totally redoing Loglan.
  • Láadan is a language from which Lojban took some of its evidentials.
  • gua\spi, which is in the same string as Nalgol. Gua\spi is a descendent of Lojban and Loglan which uses Chinese-like tones to mark grammatical structure, developed by Jim Carter. By using tones instead of structure words, and cutting predicates from two to one syllable, Carter has fixed a minor flaw in Gua\spi's predecessors – they take a lot of syllables to say things – albeit at the expense of adding tone, which is a far from universal language trait.
  • Ithkuil is a cross between a logical and philosophical language, designed to minimize ambiguity and maximize efficiency in speech.
  • Ceqli by Rex F. May is an auxiliary language project with origins in James Cooke Brown's Loglan, but has influences from English and Mandarin.
  • Plan B
  • New LoCCan is a possible next revision of Loglan/Lojban.
  • Logic Language Draft 2.1
  • Voksigid created by an Internet working group led by Bruce R. Gilson, attempts to construct a predicate language of a different type from those which had gone before. Its syntax was somewhat influenced by Japanese, and its vocabulary was based mostly on European language roots. Loglan and Lojban both use word order to mark the various places in the predication, but because remembering which position means which role in the predication might be beyond easy memorization for most people, Voksigid was designed in order to overcome this issue. It uses an extensive set of very semantically specific prepositions to mark the roles of verb arguments, instead of positional order as in Loglan and Lojban.
  • Trari is a continuation of ideas from Voksigid
  • Xorban was developed in engelang mailing list in 2012.
  • Lojsk was conceived by Ari Reyes, heavily influenced by Loglan, Lojban, Universal Networking Language (UNL), Esperanto, Visual Basic, Dutton's Speedwords, Ceqli and Gua\spi. It is designed to be more single-syllable oriented. If possible, that would nonetheless lead Lojsk to be more sensitive to noisy environments than Lojban is, therefore its practicality in oral communication may be questioned.
  • Viku (pronounced "VEE-koo") is an art language, created as an expression of Victor Medrano's personal philosophy of minimalism, simplicity, and xenophilia. Inspiration for Viku arose from Japanese and Polynesian languages. Lojban has a great influence on Viku grammar. Viku is said to be a crucible for blending primitivism with modernism.
  • X-1 and X-2
  • Fith and Shallow Fith
  • Toaq is a tonal loglang, developed by la selpa'i.
  • tanbau is a logical language developed by la tsani.
  • toki pona enhanced is a modification of toki pona based on advances of Lojban studies.
  • U - a Zen conlang, the most specified language in the world.
