Ложбан (прозносится Шаблон:IPA-art) - искусственный, синтаксически недвусмысленный человеческий язык, основанный на логике предикатов, в 1987 году Группой логического языка (англ. The Logical Language Group, ложбан la lojbangirz.) на основе предшествующего проекта Логлан. Название "Lojban" - это комбинация loj и ban, являющихся короткими формами слов logji (логический) и bangu (язык), соответственно. Развитие языка началось в 1987 Группой Логического Языка (LLG), которая намеревалась реализовать цель логлана, а также дополнить язык, сделав его более практичным и доступным свободно (как указано в его официальном полном английском названии "Ложбан: реализация логлана"). После долгого начального периода дискуссий и тестирования, базис языка был проработан в 1998 с публикацией Эталонной Грамматики Ложбана. В 2012 году в интервью газетам New York Times и Arika Okrent автор книги In the Land of Invented Languages (В стране изобретённых языков) заявил: "Сконструированный язык с наиболее полной грамматикой - это, вероятно, ложбан – язык, созданный для того, чтобы отражать принципы логики." Основными источниками его базовой лексики были шесть (на тот момент) самые распространённых языков мира по числу говорящих на них: мандаринский, английский, хинди, испанский, русский и арабский, выбранные, чтобы уменьшить чувство незнакомства и непривычности корневых слов для людей разнообразного происхождения (в языковом смысле). В языке также использованы компоненты других сконструированных языков, примечательным примером чего могжет служить набор указателей отношения и эмоций языка Láadan.

История

У ложбана есть предшественник, Loglan, язык, разработанный Джеймсом Куком Брауном в 1955 году и развивавшийся Институтом Логлана. Логлан был первоначально задуман как средство проверки влияния языка на мысли говорящего на нём (предположение, известное как гипотеза Сэпира-Уорфа).

As Brown started to claim his natural copyright on the language's components, restraint was laid on the community's activity. In order to circumvent such control, a group of people decided to initiate a separate project, departing from the lexical basis of Loglan and reinventing the whole vocabulary, which led to the current lexicon of Lojban. In effect they established in 1987 The Logical Language Group, based in Washington DC. They also won a trial over whether they could call their version of the language "Loglan".

Following the publication of The Complete Lojban Language, it was expected that "the documented lexicon would be baselined, and the combination of lexicon and reference grammar would be frozen for a minimum of 5 years while language usage grew." As scheduled, this period, which has officially been called the "freeze", expired in 2002. The speakers of Lojban are now free to construct new words and idioms, and decide where the language is heading.

Lojban still shares many of the characteristics of Loglan:

• It has a grammar that is based on predicate logic, designed to express complex logical constructs precisely.
• It has no irregularities or ambiguities in spelling and grammar (although word derivation relies on arbitrary variant forms). This gives rise to high intelligibility for computer parsing.
• It is designed to be as culturally neutral as possible.
• It allows highly systematic learning and use, compared to most natural languages.
• It possesses an intricate system of indicators which effectively communicate contextual attitudes or emotions.
• It does not have simplicity as a design criterion.

Literature and vocabulary development

Lojban can be an intellectual device for creative writing and is deemed to have many potential aspects yet to be discovered or explored.

See also the proposed fourth tense of Lojban discussed by Arthur Protin, Bob LeChevalier, Carl Burke, Doug Landauer, Guy Steele, Jack Waugh, Jeff Prothero, Jim Carter, and Robert Chassell, as well as ZAhO tenses, the concepts which "average English speakers won't recognize" because most of them (the concepts) "have no exact English counterpart".

Like most languages with few speakers, Lojban lacks much of an associated body of literature and its creative extensions have not been fully realized (the true potential of its attitudinal system, for example, is considered unlikely to be drawn out "until and unless we have children raised entirely in a multi-cultural Lojban-speaking environment"). Also such collective or encyclopedic sources of knowledge like the Lojban Wikipedia, which may help expand the language's lexical horizon, are in need of development.

Presently accessible Lojbanic writings are principally concentrated on the Lojban.org, though there exist independent Lojbanic blog/journal sites as well. The Lojban IRC (or its archive) has a gathering of Lojbanic expressions too, but its grammatical correctness is not always guaranteed. These available materials on the internet include both original works and translations of classic pieces in the field of natural languages, ranging from poetry, short story, novel, and academic writing. This has been paralleled with a chrestomathy project aiming to produce a collection of translated writings in order to show wide samplings of various language, hopefully longer than 10000 words and with a variety of genres and styles (see also – External link: Literature). Exemplary works that are already available include:

• Alice in Wonderland by the English author Lewis Carroll
• One Thousand and One Nights
• The Moon is a Harsh Mistress (Chapter 1) by the science fiction writer Robert A. Heinlein
• The Prophet by the Lebanese-American writer Kahlil Gibran
• The Little Things by the short story writer/poet Raymond Carver
• The Man and the Snake by the short story writer/satirist Ambrose Bierce
• The Book by the cosmic horror writer H. P. Lovecraft
• The Book of Esther from the Bible

Other translation projects include:

• Eaton Interface: a translation of the Helen Eaton concept list into Lojban.
• Parliamentary Rules: Lojban terms for parliamentary actions.
• Lojban Adventure: a Lojban version of the classic Colossal Cave text adventure game.

Compound words (lujvo) and borrowed words (fu'ivla) are continually increasing as the speakers find demands. The number of root words (gismu) and structure words (cmavo) are basically unchanging, but new inventions are to be accepted as experimental components. In fact, it has been noticed that particular inclination or disproportion exists in the available vocabulary. Cortesi has pointed out the lack of certain terms for mathematics and geometry (although this demand may now be disputed as the current set of Lojban vocabulary does actually allow speakers to express such notions as steradian (stero), trigonometric tangent (tanjo), multiplicative inverse (fa'i), matrix transpose (re'a) among a number of other kinds of operators or metric units). Other instances which require speakers to construct noncanonical words:

• There are few (almost non-existent) entries of African country names on the official list of root words while other country names (especially those with large populations of speakers of the six source languages) are covered to a remarkable extent.
• Such distinction as between palne (tray) and palta (plate) exist while no distinction between "illustration" and "photography" is made by the available set of gismu (that is, no exclusive root word for "photography" exists except the generic pixra (picture) (see also – Grammar: Morphology: brivla: gismu).

Development of learning aids

Apart from the actual practice of the language, some members of the community and LLG have been endeavoring to create various aids for the learners. The Complete Lojban Language (CLL, also known as The Red Book, due to its colour, and The Codex Woldemar, after its author), the definitive word on all aspects of Lojban, is one of them, finalized in 1997. Some of the projects in varying stages of completeness are:

• Phrasebook: Lojbanic Phrasebook Project, CVS/Wiki Lojban Phrasebook, Pocket Dictionary
• Parser: Lojban Parser/Machine Grammar (by Robin Lee Powell), jbofi'e (by Richard Curnow), valfendi (by Pierre Abbat)
• Database: jbovlaste (by Robin Lee Powell), Reference Database (by Matt Arnold on DabbleDB)
• Others: Lojban/Logic book and webpage (by John Clifford), TLI Loglan Interface (by Steven Belknap and Bob LeChevalier)

(see also – External link: Learning Courses/Resources)

Community development

Currently, Lojban's learning resources available on the internet are available mainly to speakers of English, French, Spanish, Russian, Hebrew, and Esperanto, to varying degrees.

Disproportion in the community population is still noticeable. It is reasonably hoped among Lojbanists that more people from different cultural/linguistic backgrounds join the community in order to maintain and further complement the intended neutrality of the language. (see also – Community)

Future goals

While the initial aim of the Loglan project was to investigate the Sapir–Whorf hypothesis, the active Lojban community recognizes additional goals for the language to be attained in the future, including but not limited to:

• Eliminating ambiguity in language
• Use as a potential International Auxiliary Language
• Use as a potential academic language, such as in science or philosophy
• Use as an educational tool
• Research in linguistics
• Research in artificial intelligence and machine understanding
• Improved human-computer communication, storage ontologies, and computer translation of natural language text
• Improved human-human communication, due to the logical and unambiguous structure and greater means of expression

Note that these goals are not crucial to the Lojban community, most of whom simply want to enjoy communicating with each other in Lojban.

Grammar

Phonology and orthography

Lojban has 6 vowels and 17 consonants. Some of them have, apart from the preferred/standard sounds, permitted variants intended to cover dissimilitude in pronunciation by speakers of different linguistic backgrounds.

Stress normally falls on the penultimate syllable.

There are 16 diphthongs (and no triphthongs). A distinction between diphthongs and monophthongs can be written by inserting a comma in the Latin alphabet. Vowel hiatus is also prevented by inserting an apostrophe, which usually indicates [h], though there are other valid realizations. For those who have trouble pronouncing certain consonant clusters, there is the option of adding vowels between them (epenthesis), as long as they differ sufficiently from the phonological vowels and are pronounced as short as possible. The resulting additional syllables are not factored in the grammar, including for the purposes of stress determination.

Lojban is written almost entirely with lower-case letters; upper-case letters are used to mark stress in words that do not fit the normal rules of stress assignment, or when whitespace is omitted.

The letters in Lojban and their respective pronunciations are shown in the table below. The IPA symbols in parentheses indicate alternative pronunciations; preferred pronunciations have no parentheses.

In principle, Lojban may be written in any orthographic system as long as it satisfies the required regularities and unambiguities. Some of the reasons for such elasticity would be as follows:

1. Lojban is defined by the phonemes rather than graphemes; as long as they are correctly rendered so as to maintain the Lojbanic audio-visual isomorphism, a representational system can be said to be an appropriate orthography of the language;
2. Lojban is meant to be as culturally neutral as possible, so it is never crucial or fundamental to claim that some particular orthography of some particular languages (e.g. the Latin alphabet) should be the dominant mode.

Some Lojbanists extend this principle to claim that even an original orthography of the language is to be sought.

This article will use the common Latin alphabet mode.

Morphology

Lojban has three word-classes: predicate words (brivla), structure words (cmavo), and name words (cmevla). Each of them has uniquely identifying properties, so that one can unambiguously recognize which word is of which part of speech in a string of the language. They may be further divided in sub-classes. There also exists a special fragmental form assigned to some predicate words and structure words, from which compound words (lujvo) may be created.

Syntax and semantics

The language's grammatical structures are "defined by a set of rules that have been tested to be unambiguous using computers", which is in effect called the "machine grammar". Hence the characteristics of the standard syntactic (not semantic) constructs in Lojban:

• each word has exactly one grammatical interpretation;
• the words relate grammatically to each other in exactly one way.

Such standards, however, are to be attained with certain carefulness:

The computer-tested, unambiguous rules also include grammar for 'incomplete' sentences e.g. for narrative, quotational, or mathematical phrases.

Lojbanic expressions are modular; smaller constructs of words are assembled into larger phrases so that all incorporating pieces manifest as a possible grammatical unity. This mechanism allows for simple yet infinitely powerful phrasings; "a more complex phrase can be placed inside a simple structure, which in turn can be used in another instance of the complex phrase structure".

Its typology can be said to be basically subject–verb–object and subject–object–verb. However, it can practically be anything:

• mi prami do (SVO) (I love you)
• mi do prami (SOV) (By me, you are loved)
• do se prami mi (OVS) (You are loved by me)
• do mi se prami (OSV) (You, I love)
• prami fa mi do (VSO) (Loved by me, you are)
• prami do fa mi (VOS) (Love you, I do)

Such flexibility has to do with the language's intended capability to translate as many expressions of natural languages as possible, based on a unique positional case system. The meaning of the sentence {mi prami do} is determined by {prami} realizing, with its own predefined "place structure", a specific semantic relation between {mi} and {do}; when the positional relation between {mi} and {do} changes, the meaning of the sentence changes too. As shown above, Lojban has particular devices to preserve such semantic structure of words while altering their order.

As befits a logical language, there is a large assortment of logical connectives. Such conjunction words take different forms depending on what they connect, another reason why the (standard) Lojbanic expressions are typically precise and clear.

Multiple predicate words may be linked up together so as to narrow the semantic scope of the phrase. In skami pilno "computer user(s)", the modifying word skami narrows the sense of the modified word pilno to form a more specific concept (in which case the modifier may resemble English adverbs or adjectives).

• English: Several small fires were burning in the house.
• Lojban: so'i cmalu fagri puca'o jelca ne'i le zdani
• Gloss: many small fire past-continuing burn inside the house (Translation after English)

One could go still further, adding a quite extreme example of its syntactical flexibility.

Lojban can easily "imitate" even Amerindian one-word sentences like this one:

• Nuu-chah-nulth language: inikwihl'minik'isit
• Lojban: zdane'ikemcmafagyso'ikemprununjelca (so-called lujvo or compound word mainly using the underlying rafsi or roots according to strict compositional rules)
• Gloss: (about) house-inside type-of small fire multitude type-of past event type of burning

The Nuu-chah-nulth one-word sentence breaks down a bit differently as:

inkiw (fire/burn) -ihl (in-the-house) -'minik (plural) -'is (diminutive) -'it (past-tense)

which can be readily expressed in Lojban the same way:

• Lojban: fagykemyzdanerso'icmapru
• Gloss: fire-type-house-inside-many-small-past-event

The Logfest

Gatherings of Lojbanists have been organized in USA annually since as early as 1990, called Logfest. It is mostly informal, taking place on a weekend, with the only scheduled activity being the annual meeting of the LLG. Those who cannot be present may still be involved via IRC. Activities may be whatever the attendees want to do: Lojban conversation, lessons, technical discussions, or socializing.

Population

The total number of Lojban speakers is unknown.

According to Lojban.org, places known to have concentration of Lojbanists are:

• Australia, Israel, United States

Also Frappr.com shows that, as of August 2007, some people from the following countries are interested in or enthusiasts of the language:

• Argentina, Canada, China, Estonia, France, Germany, Ireland, Mexico, The Netherlands, New Zealand, Norway, Russia, Thailand, Ukraine, United Kingdom, Venezuela.

Below are some of the notable personalities who have contributed to the development of Lojban:

• Bob LeChevalier (aka lojbab): the president of the LLG.
• John Cowan (aka jcowan): the author of The Complete Lojban Language.
• Jorge Llambías (aka xorxes): one of the most active Lojbanists, having done several translations. He is also a prominent figure on the mailing list, helping beginners with the language.
• Matt Arnold (aka epkat): one of the most active Lojbanists. He has been contributing to the translation project and software development.
• Nick Nicholas (aka nitcion): an Australian linguist. He is the first fluent Lojban speaker (although he insists that he was the second; he is known to be excessively modest). He has done Lojbanic writing, including Lojban For Beginners coauthored by Robin Turner.
• Robin Lee Powell (aka camgusmis): the current webmaster of Lojban.org. He provides the machine and bandwidth from which the site is served. He has also written several Lojbanic materials including a novel-sized story, la nicte cadzu (Night Walkers).
• Robin Turner: a British philosopher and linguist living in Turkey. He is the coauthor of Lojban For Beginners.

Comparison with other logical languages

Loglan

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.

The principal difference between Lojban and Loglan is one of lexicon. A Washington DC splinter group, which later formed The Logical Language Group, LLG, decided in 1986 to remake the entire vocabulary of Loglan in order to evade Dr. Brown's claim of copyright to the language. After a lengthy battle in court, his claim to copyright was ruled invalid. But by then, the new vocabulary was already cemented as a part of the new language, which was called Lojban: A realization of Loglan by its supporters.

The closed set of five-letter words was the first part of the vocabulary to be remade. The words for Lojban were made by the same principles as those for Loglan; that is, candidate forms were chosen according to how many sounds they had in common with their equivalent in some of the most commonly spoken languages on Earth, which was then multiplied by the number of speakers of the languages with which the words had letters in common. The difference with the Lojban remake of the root words was that the weighting was updated to reflect the actual numbers of speakers for the languages. This resulted in word forms that had fewer sounds taken from English, and more sounds taken from Chinese. For instance, the Loglan word norma is equivalent to the Lojban word cnano (cf. Chinese 常, pinyin cháng), both meaning "normal".

Grammatical words were gradually added to Lojban as the grammatical description of the language was made.

Loglan and Lojban still have essentially the same grammars, and most of what is said in the Grammar section above holds true for Loglan as well. Most simple, declarative sentences could be translated word by word between the two languages; but the grammars differ in the details, and in their formal foundations. The grammar of Lojban is defined mostly in the language definition formalism YACC, with a few formal "pre-processing" rules. Loglan also has a machine grammar, but it is not definitive; it is based on a relatively small corpus of sentences that has remained unchanged through the decades, which takes precedence in case of a discrepancy.

There are also many differences in the terminology used in English to talk about the two languages. In his writings, Brown used many terms based on English, Latin and Greek, some of which were already established with a slightly different meaning. On the other hand, the Lojban camp freely borrowed grammatical terms from Lojban itself. For example, what linguists call roots or root words, Loglanists call primitives or prims, and Lojbanists call gismu. The lexeme of Loglan and selma'o of Lojban have nothing to do with the linguistic meaning of lexeme. It is a kind of part of speech, a subdivision of the set of grammatical words, or particles, which loglanists call little words and lojbanists cmavo. Loglan and Lojban have a grammatical construct called metaphor and tanru, respectively; this is not really a metaphor, but a kind of modifier-modificand relationship, similar to that of a noun adjunct and noun. A borrowed word in Loglan is simply called a borrowing; but in English discussions of Lojban, the Lojban word fu'ivla is used. This is probably because in Lojban, unlike Loglan, a certain set of CV templates is reserved for borrowed words.

In the new phonology for Lojban, the consonant q and the vowel w were removed, and the consonant h was replaced by x. The consonant ' (apostrophe) was added with the value of [h] in the International Phonetic Alphabet, but its distribution is such that it can appear only intervocally, and in discussions of the morphology and phonotactics, it is described not as a proper consonant, but a "voiceless glide". (This phoneme is realized as [θ] by some speakers.) A rigid phonotactical system was made for Lojban, but Loglan does not seem to have had such a system.

Lojsk

Lojsk was conceived by Ari Reyes, heavily influenced by Loglan, Lojban, Universal Networking Language (UNL), Esperanto, Visual Basic, Dutton's Speedwords, Ceqli and Gua\spiШаблон:Citation needed. 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 isШаблон:Says who, therefore its practicality in oral communication may be questionedШаблон:Ref.

Voksigid

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.

Gua\spi

Gua\spi is a descendent of Lojban and Loglan but is tonal, developed by Jim Carter. Instead of structure words there are in Gua\spi six different tones. Predicates have only one syllable instead of two. Some of its characteristics, including tones, phonotactics, expressions for masses vs sets, non-existence of metalinguistic negation, etc, received criticism.
