Ido (pronEng|ˈiːdoʊ) is a constructed language created with the goal of becoming a universal second language for speakers of different linguistic backgrounds as a language easier to learn than ethnic languages. This intended usage parallels the current use of English as a lingua franca, and of French, Latin, and Greek in earlier eras. Unlike English, which is a natural and frequently irregular language, Ido was specifically designed for grammatical, orthographic, and lexicographical regularity, and to favor no one who might otherwise be advantaged in a situation due to native fluency in a widespread language. In this sense, Ido is classified as a consciously created International Auxiliary Language (conIAL). Of the most widely used conIALs, the first one is Esperanto, Ido's predecessor; it is disputable whether the second place in usage goes to Ido or Interlingua.

Ido was developed in the early 1900s, and retains a sizable following today, primarily in Europe. It is largely based on Esperanto, created by L. L. Zamenhof. Ido first appeared in 1907 as a result of a desire to reform perceived flaws in Esperanto that some of its supporters believed to be a hindrance in its propagation as an easy-to-learn second language. Many other reform projects appeared after Ido: examples such as Occidental and Novial appeared afterwards but have since faded into obscurity. At present, Ido along with Esperanto and Interlingua are the only auxiliary languages with a large body of literature and a relatively large speaker base. The name of the language likely traces its origin to the Ido pronunciation of "I.D." (from "International Delegation", see below) or the word "esperantido", "descendant (of Esperanto)". Or, as with the case of "Esperanto", it could simply be adopted from the pseudonym its designer (Louis Couturat) used in presenting the language to the Delegation Committee. In IDO, it is simply an abbreviation of "Idiomo Di Omni" (language for all).

Ido uses the 26 Latin letters used in the English alphabet with no diacritics. While still being completely morphologically regular, Ido resembles the Romance languages in appearance and is sometimes mistaken for Italian or Spanish at first glance. Ido is largely intelligible to those who have studied Esperanto, though there are certain differences in word formation, grammar and grammatical-function words that make it more than a simple reform project. Ido is a stand-alone language.Fact|date=August 2008

After its inception, Ido gained support (estimates generally range around 20% ["Ido-movado". (2005, novembro 15). Vikipedio, La Libera Enciklopedio. Retrieved 19:04, novembro 28, 2005 from http://eo.wikipedia.org/w/index.php?title=Ido-movado&oldid=321224.] ) from some in the Esperanto community at the time, but following the sudden death in 1914 of one of its most influential proponents, Louis Couturat, it declined in popularity. There were two reasons for this: first, the emergence of further schisms arising from competing reform projects; and second, a general lack of awareness of Ido as a candidate for an international language. These obstacles weakened the movement and it was not until the rise of the Internet that it began to regain its former momentum.

History

The idea of a universal second language is not new, and constructed languages are not a recent phenomenon. The first known constructed language was created in the 12th century by St Hildegard of Bingen under the name Lingua Ignota. But the idea did not catch on in large numbers until the 19th century with the language Volapük, created in 1879 by German Catholic priest Johann Martin Schleyer. Volapük was popular for some time and apparently had a few thousand users, but was later eclipsed by the popularity of Esperanto, which arose from L. L. Zamenhof's book Unua Libro in 1887. The simpler grammar and less changed vocabulary of Esperanto appealed to many, and its popularity quickly rose. The first World Congress of Esperanto was held in 1905. However, some within the Esperanto community itself felt that the language should undergo further reform before being officially selected as a universal second language. It was at this time that Couturat formed the "Delegation for the Adoption of an International Auxiliary Language."

This delegation made a formal request to the International Association of Academies in Vienna to select an international language; the request was rejected in May 1907. The Delegation then decided to meet as a Committee in Paris in October 1907 to discuss the adoption of a standard international language among the various competitors that had been devised till then. According to the minutes of the Committee, it was decided that no language was completely acceptable, but that Esperanto could be accepted "on condition of several modifications to be realized by the permanent Commission in the direction defined by the conclusions of the Report of the Secretaries (Couturat and Leopold Leau) and by the Ido project." This (anonymous) "Ido project" was later suggested to have been primarily devised by Couturat with some help from Esperanto's representative before the Committee, Louis de Beaufront. Beaufront had himself argued for reforming Esperanto before he was selected to the Delegation. His eventual "conversion" to the Ido camp, upon the presentation of that language, was thus consistent with his earlier positions.

Early supporters of Esperanto tended to resist reforms, and its inventor, Zamenhof, deferred to their judgment. Several of the reforms adopted by Ido were themselves proposed at various times by Zamenhof, especially in 1894 when he proposed eliminating the accented letters and the accusative case (referring to it as "superfluous ballast" [ [http://web.archive.org/web/20021228070110/http://www.geocities.com/Paris/Rue/8009/idolinguo/054_074.html History of the International Language] ] ), changing the plural to an Italianesque "-i", and replacing the table of correlatives with more Latinate words (see History of Esperanto and Reformed Esperanto). The custom of keeping the basic rules of Esperanto fixed remains today.

Couturat, who was the leading proponent of Ido, was killed in an automobile accident in 1914, which, along with World War I, dealt a serious blow to the Ido movement. Although that movement recovered to some degree in the immediate postwar period, the whole movement of international languages became balkanized. With the publication of an even more Europeanized planned language, Occidental, in 1922, Ido went into decline. The Ido movement lost a majority of its published periodicals in the subsequent year or so, and the defection of its major intellectual supporter, the Danish linguist Otto Jespersen, in 1928 on the occasion of the publication of his own planned language Novial, seemed at the time to provide a quietus.

Some observers trace the eclipse of Ido to its hybrid character – part Esperanto reform project, part Standard Average European (see Sapir–Whorf hypothesis). In this view, once it was clear that Ido would neither displace Esperanto nor be adopted by the Esperanto community, many viewed its Esperanto-like features as unnecessary baggage and moved on to more naturalistic projects. Those who approved of them tended to return to the larger Esperanto community.

Ido's decline had slowed by the 1930s, and the movement was still a significant force in interlinguistics during the long gestation of the International Auxiliary Language Association's project. Like the Occidentalists, many Idists hoped that IALA would produce a language relatively close to their own preferences. In the end, the radically naturalistic Interlingua was even farther from Ido than Occidental, and (in contrast to Occidental) there was no major migration of Ido supporters to the new language.

Ido's survival during this period was assisted by financial resources accumulated during its heyday (e.g., the chemist Wilhelm Ostwald had donated the proceeds of his 1909 Nobel Prize to an Ido foundation).

The language still has active speakers today, and the Internet has sparked a renewal of interest in the language in recent years. The estimates of the number of speakers range from 2000 to 5000. In comparison, Esperanto has at least 100,000 (Sidney S. Culbert's widely cited estimate of 1.6 million speakers is controversial).

Jespersen, who was present during the ten days of Committee deliberations in Paris and later served as part of the permanent Commission, wrote a history of Ido. [Jespersen, Otto. "History of our Language (Ido)" from http://www.geocities.com/Athens/Forum/5037/Hist.html - 1912. Translated from the original Ido available at http://www.geocities.com/Athens/Forum/5037/OJhist.html]

A number of Esperanto supporters have attacked Ido over the years. The Esperantist Don Harlow has characterized Ido's founders as underhanded and conspiratorial;Harlow, Don. "The Esperanto Book", chapter 3: [http://donh.best.vwh.net/Esperanto/EBook/chap03.html "How to Build a Language"] .] see also Emile Boirac's report in the list of external links; also Gaston Waringhien's “Kulisaj manovroj” (Maneuvers in the Wings) in his "1887 kaj la sekvo", Antwerp: Stafeto, 1980. However, most Ido partisans argue that Harlow's history is polemical and is not consistent with all the eyewitness accounts, such as those reported by Jespersen. Harlow bases his account on material from some other eyewitnesses such as Emile Boirac and Gaston Moch and with other source documentation (such as Zamenhof's correspondence with Couturat and others during the period, as published in the two-volume "Leteroj de Zamenhof", Paris: SAT, 1948), to which Jespersen, according to Harlow, would not have had access.

Comparison with Esperanto

Ido inherits many features of the grammar of Esperanto, and in many cases, the vocabulary is similar. Ido shares with Esperanto the goals of grammatical simplicity and consistency, ease of learning, and the use of loanwords from various European languages. The two languages, to a great extent, are mutually intelligible. However, certain changes were introduced to address some of the concerns that had arisen about Esperanto. These include:

* Esperanto's alphabet uses six non-Latin letters, three of which are not found in any other existing language; as a result, Esperanto in typing and in Internet e-mail and newsgroups frequently resorts to any of several schemes to represent these special letters. This leads to the situation where the same word may be displayed any of several different ways. Ido addresses this issue by using the 26-letter Latin alphabet with two digraphs, "ch" (IPA|/ʧ/) and "sh" (IPA|/ʃ/) instead of Esperanto's "ĉ" and "ŝ". The digraph "qu", representing IPA|/kw/, as in English "quick", is used instead of Esperanto "kv", and likewise "gu" is used instead of "gv". Ido orthography is phonetic in the sense that each written word has an unambiguous pronunciation, but it does not have the one-to-one correspondence between letters and phonemes that Esperanto has.
* Ido generally does not impose rules of grammatical agreement between grammatical categories within a sentence, believing them to be grammatically complex and redundant in a potential universal second language. For example, in Esperanto, the verb in a sentence is invariable regardless of the number and person of the subject. This principle was not extended in Esperanto to adjectives and nouns, however; as a result, in Esperanto an adjective must agree in number and case with the noun it modifies as with the French "grands livres" (large books), where the adjective must be pluralized as well as the noun. There is no such requirement in English; for example, where number is emphasized by variation of the verb, and Ido eliminates this feature from its grammar.
* Esperanto requires the use of the "-n" ending to signify the use of the accusative case. Ido allows the use of this feature in ambiguous situations where the object of a sentence does not follow the subject, but in all other situations, the accusative case was eliminated as redundant.
* Ido imposes consistent rules on the use of endings to transform a word from one meaning or part of speech to another, thus simplifying the amount of vocabulary memorization that is necessary.
* Ido, unlike Esperanto, does not assume the male sex as the default for family relationship words. For example, Ido does not derive the word for "sister" by adding a feminine suffix to the word for "brother", as standard Esperanto does. Instead, some relationship root words are defined as sex neutral, and two different suffixes derive masculine- and feminine-specific words from the root—frato (sibling) > fratulo (brother), fratino (sister). In other cases, Ido has two or three root words where Esperanto has one—genitoro (parent), patro (father), matro (mother).
* Ido's vocabulary attempts to use cognates that are shared in common by as many of its six source languages as possible.Nevertheless, modern Esperanto has received some influence from Ido in areas such as a clarification of the rules for word derivation and suffixes like "-oz-" ("abundant in") and "-end-" ("required to").

Phonology

Ido has the same typical five-vowel system (a, e, i, o, u have their values) as Esperanto, and most of the same consonants, omitting two consonant phonemes used by Esperanto, IPA IPA|/x/ and IPA|/dʒ/. (The distinctions between IPA|/x/ : /h/ and between IPA|/dʒ/ : /ʒ/ carry a very low functional load in Esperanto, and so were deemed to be unnecessary in Ido.) Without those two consonant phonemes, the consonants in the language are as follows:

# "ci", while technically the familiar form of the word "you" in Esperanto, is almost never used. Results on Google have shown that while "tu" is only slightly less common than "vu" in Ido, "ci" is used less than half of one percent of the amount "vi" is in Esperanto. Esperanto's inventor himself did not include the pronoun in the first book on Esperanto and only later reluctantly; later he recommended against using "ci" on the grounds that different cultures have conflicting traditions regarding the use of the familiar and formal forms of "you", and that a universal language should avoid the problem by simply using the formal form in all situations. Unlike some other languages that use a formal second person pronoun, "vi" is not capitalized. [Eventoj, no. 103, ISSN 01215-959 X. "Ci" estas senvalora balasto ("Ci" is useless ballast). 1996. Available at http://www.eventoj.hu/arkivo/eve-103.htm]
# "tiu", though not a personal pronoun, is usually used in this circumstance, because many people have a hard time applying "it" to humans.

It should be noted that "ol", like English "it" and Esperanto "ĝi", is not limited to inanimate objects, but can be used "for entities whose sex is indeterminate: "babies, children, humans, youths, elders, people, individuals, horses, cows, cats," etc."

"Lu" is often mistakenly labeled an epicene pronoun, that is, one that refers to both masculine and feminine beings, but in fact, "lu" is more properly a "pan-gender" pronoun, as it is also used for referring to inanimate objects. From "Kompleta Gramatiko Detaloza di la Linguo Internaciona Ido" by Beaufront:

"Lu" (like "li") is used "for all three genders." That "lu" does duty for the three genders at will in the singular is not in itself any more astonishing than seeing "li" serve the three genders at will in the plural ... By a decision (1558) the Idist Academy rejected every restriction concerning the use of "lu." One may thus use that pronoun in exactly the same way for a thing and a person of obvious sex as for animals of unknown sex and a person that has a genderless name, like "baby, child, human," etc., these being as truly masculine as feminine.

The motives for this decision were given in "Mondo", XI, 68: "Lu" for the singular is exactly the same as "li" for the plural. Logic, symmetry and ease demand this. Consequently, just as "li" may be used for people, animals, and things whenever nothing obliges one to express the gender, so "lu" may be used for people, animals, and things under the same condition. The proposed distinction would be a bothersome subtlety...

Vocabulary

Vocabulary in Ido is based on words intended to give the greatest facility to the most speakers. Early on, the first 5000+ roots were analyzed compared to the vocabulary of English, French, Spanish, German, Russian and Italian, and the following result was found: [L. H. Dyer. "The Problem of an International Auxiliary Language and its Solution in Ido", pp. 101–124 [http://www.geocities.com/Paris/Rue/8009/idolinguo/101_121.htm] , 1923.]

*2024 roots (38%) belong to 6 languages
*942 roots (17%) belong to 5 languages
*1111 roots (21%) belong to 4 languages
*585 roots (11%) belong to 3 languages
*454 roots (8%) belong to 2 languages
*255 roots (5%) belong to 1 language
**Total 5371 100%

In addition, a comparison of Ido vocabulary to the six shows the following for the similarities of Ido to the six languages above:

*French 4880: 91%
*Italian 4454: 83%
*Spanish 4237: 79%
*English 4219: 79%
*German 3302: 61%
*Russian 2821: 52%

This is consistent with the fact that Ido is sometimes mistaken for French, Italian or Spanish at first sight.

Comparison of vocabulary with the six languages:

Vocabulary in Ido is often created through a number of official prefixes and suffixes that alter the meaning of the word. This allows a user to take existing words and modify them to create neologisms when necessary, and allows for a wide range of expression without the need to learn new vocabulary each time. Though their number is too large to be included in one article, some examples include:
*The diminutive suffix -et-. Domo (house) becomes dometo (cottage), and libro (book) becomes libreto (novelette or short story).
*The pejorative suffix -ach-. Domo becomes domacho (hovel), and libro becomes libracho (a shoddy piece of work, pulp fiction, etc.)
*The prefix retro-, which implies a reversal. Irar (to go) becomes retroirar (to go back, backward) and venar (to come) becomes retrovenar (to return).

New vocabulary is generally created through an analysis of the word, its etymology, and reference to the six source languages. If a word can be created through vocabulary already existing in the language then it will usually be adopted without need for a new radical (such as wikipedio for "Wikipedia", which consists of wiki + enciklopedio for "encyclopedia"), and if not an entirely new word will be created. The word alternatoro for example was adopted in 1926, likely because five of the six source languages used largely the same orthography for the word, and because it was long enough to avoid being mistaken for other words in the existing vocabulary. ["Lexiko di nova vorti" (lexicon of new words), available at http://www.geocities.com/Athens/Forum/5037/nova.html] Adoption of a word is done through consensus, after which the word will be made official by the union. Care must also be taken to avoid homonyms if possible, and usually a new word undergoes some discussion before being adopted. Foreign words that have a restricted sense and are not likely to be used in everyday life (such as the word "intifada" to refer to the conflict between Israel and Palestine) are left untouched, and often written in italics.

Ido-speaking community

As with all constructed languages, gauging the number of speakers of Ido is an extremely difficult task. Usenet postings by the prominent Esperantist Don Harlow have estimated the population at being somewhere in the thousands, but no accurate numbers exist. Moreover, given the often political IAL environment in which those that speak a language are not merely language users but adherents to its system and linguistic philosophy as well, there are two categories of those that know the language, Ido "speakers" and Ido "supporters". Ido resembles Esperanto to a large extent, and many Esperantists have learned Ido out of curiosity while still not using it, preferring to support the more well-known Esperanto movement instead. One Esperanto bulletin board included the following:

It is possible to find discussions of this nature on the Internet in English, Esperanto, Ido, Interlingua and other IALs, each understanding the other with little problem. [ [http://groups.google.com/group/bablo/tree/browse_frm/thread/12352c9b3e8d3f5d/2f8fbd25388dc8ca?rnum=1&q=esas+estas+non&_done=%2Fgroup%2Fbablo%2Fbrowse_frm%2Fthread%2F12352c9b3e8d3f5d%2Fb0b69d354b5ca8ed%3Flnk%3Dgst%26q%3Desas%2Bestas%2Bnon%26#doc_2f8fbd25388dc8ca Google Groups discussion in multiple planned languages] ]

A number of Esperantists viewed the schism of Ido as a mixed blessing, and a number of writings show that some were inversely glad to see those who were interested only in creating a perfect language by constantly reforming it leave the fold so that those remaining could work on using and promoting the language itself. However, these "constant reformers" eventually moved on to other reform projects, few of which survived much beyond the deaths of the authors themselves, and Ido has remained constant since then—it is safe to say that were Ido a community of language reformers during its early days, that this is not the case anymore. [Chandler, James. "Changes in Ido since 1922", from http://www.geocities.com/Athens/Forum/5037/changes.html]

A small sample of 24 Idists on the Yahoo! group "Idolisto" during late 2005 showed that 57% had begun their studies of the language during the past three years, 32% from the mid-1990s to 2002, and 8% had known the language from before.Fact|date=September 2008

Literature and publications

Ido has a number of publications that can be subscribed to or downloaded for free in most cases. "Kuriero Internaciona" is a magazine produced in France every few months with a range of topics. "Adavane!" is a magazine produced by the Spanish Ido Society every two months that has a range of topics, as well as a few dozen pages of work translated from other languages. "Progreso" is the official organ of the Ido movement and has been around since the inception of the movement in 1908. Other sites can be found with various stories, fables or proverbs along with a few books of the Bible translated into Ido on a smaller scale. The site "publikaji" has a few podcasts in Ido along with various songs and other recorded material.

The online encyclopedia Wikipedia includes an [http://io.wikipedia.org/ Ido-language edition] (known in Ido as "Wikipedio"); as of December 2007, it has over 15,000 articles.
