for international communication, or "the international language" (). Zamenhof first described the language in ''
Dr. Esperanto's International Language'' (), which he published under the pseudonym . Early adopters of the language liked the name ''Esperanto'' and soon used it to describe his language. The word translates into English as "one who hopes".
Within the range of constructed languages, Esperanto occupies a middle ground between "naturalistic" (imitating existing natural languages) and
''a'priori'' (where features are not based on existing languages). Esperanto's

also influenced the grammar and phonology. One of the language's most notable features is its
extensive system of derivation, where prefixes and suffixes may be freely combined with roots to generate words, making it possible to communicate effectively with a smaller set of words.
Esperanto is the most successful constructed international auxiliary language, and
the only such language with a sizeable population of
native speakers, of which there are perhaps several thousand.
Usage estimates are difficult, but two estimates put the number of people who know how to speak Esperanto at around 100,000.
Concentration of speakers is highest in Europe, East Asia, and South America. Although no country has adopted Esperanto officially, ("Esperanto-land") is used as a name for the collection of places where it is spoken. The language has also gained a noticeable presence on the internet in recent years, as it became increasingly accessible on platforms such as

History
Creation
Esperanto was created in the late 1870s and early 1880s by
L. L. Zamenhof, a
Polish-Jewish ophthalmologist from

. In the 1870s, just a few years before Zamenhof created Esperanto,
Polish was banned in public places in Białystok.
According to Zamenhof, he created the language to reduce the "time and labor we spend in learning foreign tongues", and to foster harmony between people from different countries: "Were there but an international language, all translations would be made into it alone ... and all nations would be united in a common brotherhood."
[L.L.Zamenhof]
International Language
. Warsaw. 1887 His feelings and the situation in Białystok may be gleaned from an extract from his letter to Nikolai Borovko:
Zamenhof's goal was to create an easy and flexible language that would serve as a universal

and international understanding, and to build a "community of speakers".
His original title for the language was simply "the international language" (), but early speakers grew fond of the name ''Esperanto,'' and began to use it as the name for the language just two years after its creation. The name quickly gained prominence, and has been used as an official name ever since.
In 1905, Zamenhof published the ''
Fundamento de Esperanto'' as a definitive guide to the language. Later that year, French Esperantists organized with his participation the first
World Esperanto Congress, an ongoing annual conference, in
Boulogne-sur-Mer, France. Zamenhof also proposed to the first congress that an independent body of linguistic scholars should steward the future evolution of Esperanto, foreshadowing the founding of the
Akademio de Esperanto (in part modeled after the
Académie Française

, they have been attended by an average of more than 2,000 people, and up to 6,000 people at the most.
Zamenhof wrote that he wanted mankind to "learn and use ... en masse ... the proposed language as a living one".
The goal for Esperanto to become a
global auxiliary language was not Zamenhof's only goal; he also wanted to "enable the learner to make direct use of his knowledge with persons of any nationality, whether the language be universally accepted or not; in other words, the language is to be directly a means of international communication."
After some ten years of development, which Zamenhof spent translating literature into Esperanto, as well as writing original prose and verse, the
first book of Esperanto grammar was published in
Warsaw

on July 26, 1887. The number of speakers grew rapidly over the next few decades; at first, primarily in the Russian Empire and Central Europe, then in other parts of Europe, the Americas, China, and Japan. In the early years before the world congresses, speakers of Esperanto kept in contact primarily through correspondence and periodicals.
Zamenhof's name for the language was simply ("International Language"). December 15, Zamenhof's birthday, is now regarded as
Zamenhof Day or Esperanto Book Day.
20th century

The autonomous territory of
Neutral Moresnet, between what is today Belgium and Germany, had a sizable proportion of Esperanto-speakers among its small and multi-ethnic population. There was a proposal to make Esperanto its official language.
However, neither Belgium nor Germany had ever surrendered its original claim to it. Around 1900, Germany, in particular, was taking a more aggressive stance towards the territory and was accused of sabotage and of obstructing the administrative process to force the issue. It was the First World War, however, that was the catalyst that brought about the end of neutrality. On August 4, 1914, Germany invaded Belgium, leaving Moresnet at first "an oasis in a desert of destruction". In 1915, the territory was annexed by the Kingdom of Prussia, without international recognition. Germany lost the war, Moresnet was returned to Belgium, and today it is the German-speaking Belgian municipality of
Kelmis.
After the Great War, a great opportunity seemed to arise for Esperanto when the Iranian delegation to the

. Ten delegates accepted the proposal with only one voice against, the French delegate,
Gabriel Hanotaux. Hanotaux opposed all recognition of Esperanto at the League, from the first resolution on December 18, 1920, and subsequently through all efforts during the next three years. Hanotaux did not approve of how the French language was losing its position as the international language and saw Esperanto as a threat, effectively wielding his veto power to block the decision. However, two years later, the League recommended that its member states include Esperanto in their educational curricula. The French government retaliated by banning all instruction in Esperanto in France's schools and universities.
The French Ministry of Public Instruction said that "French and English would perish and the literary standard of the world would be debased".
Nonetheless, many people see the 1920s as the heyday of the Esperanto movement. During this time,

Esperanto has been described as "a language
lexically predominantly
Romanic,
morphologically intensively
agglutinative, and to a certain degree
isolating in character".
Typologically, Esperanto has
prepositions and a
pragmatic word order that by default is ''
subject–verb–object'' (SVO). Adjectives can be freely placed before or after the nouns they modify, though placing them before the noun is more common. New words are formed through extensive

Phonology
Esperanto typically has 22 to 24 consonants (depending on the phonemic analysis and individual speaker), five vowels, and two

) can cause problems with printing and computing, because they are not found on most physical keyboards and are left out of certain fonts.
There are two principal workarounds to this problem, which substitute
digraphs for the accented letters. Zamenhof, the inventor of Esperanto, created an "h-convention", which replaces ''ĉ, ĝ, ĥ, ĵ, ŝ,'' and ''ŭ'' with ''ch, gh, hh, jh, sh,'' and ''u,'' respectively. If used in a database, a program in principle could not determine whether to render, for example, ''ch'' as ''c'' followed by ''h'' or as ''ĉ'', and would fail to render, for example, the word properly, unless its component parts were intentionally separated, as in e.g. ''senc·hava''. A more recent "
x-convention" has gained ground since the advent of computing. This system replaces each diacritic with an ''x'' (not part of the Esperanto alphabet) after the letter, producing the six digraphs ''cx, gx, hx, jx, sx,'' and ''ux''.
There are computer
keyboard layouts that support the Esperanto alphabet, and some systems use software that automatically replaces x- or h-convention digraphs with the corresponding diacritic letters (for example, for

Criticisms are levied against the letters with circumflex diacritics, which some find odd or cumbersome, along with their being invented specifically for Esperanto rather than borrowed from existing languages. Additionally, some of them are arguably unnecessary — for example, the use of ''ĥ'' instead of ''x'' and ''ŭ'' instead of ''w''.
However, Zamenhof did not choose these letters arbitrarily: In fact, they were inspired by Czech letters with the
caron diacritic but replaced the caron with a circumflex for the ease of those who had access to a French typewriter (with a circumflex
dead-key). The Czech letter ''ž'' was replaced with ''ĵ'' to match the French letter ''j'' with the same sound. The letter ''ŭ'' on the other hand comes from the
u-breve used in
Latin prosody, and is also speculated to be inspired by the
Belarusian Cyrillic letter ''
ў''; French typewriters can render it approximately as the French letter ''ù''.

Vocabulary
The core vocabulary of Esperanto was defined by , published by Zamenhof in 1887. This book listed 900 roots; these could be expanded into tens of thousands of words using prefixes, suffixes, and compounding. In 1894, Zamenhof published the first Esperanto
dictionary

, , which had a larger set of roots. The rules of the language allowed speakers to borrow new roots as needed; it was recommended, however, that speakers use most international forms and then derive related meanings from these.
Since then, many words have been borrowed, primarily (but not solely) from the European languages. Not all proposed borrowings become widespread, but many do, especially
technical and
scientific terms. Terms for everyday use, on the other hand, are more likely to be derived from existing roots; "computer", for instance, is formed from the verb "compute" and the suffix "tool". Words are also

from its usage in many languages (English ''mouse'', French ''souris'', Dutch ''muis'', Spanish ''ratón'', etc.). Esperanto speakers often debate about whether a particular borrowing is justified or whether meaning can be expressed by deriving from or extending the meaning of existing words.
Some compounds and formed words in Esperanto are not entirely straightforward; for example, , literally "give out", means "publish", paralleling the usage of certain European languages (such as German ''herausgeben'', Dutch ''uitgeven'', Russian ''издать izdat'''). In addition,
the suffix ''-um-'' has no defined meaning; words using the suffix must be learned separately (such as "to the right" and "clockwise").
There are not many idiomatic or slang words in Esperanto, as these forms of speech tend to make international communication difficult—working against Esperanto's main goal.
Instead of derivations of Esperanto roots, new roots are taken from European languages in the endeavor to create an international language.

At that time the dragon was a symbol of the supernatural creature. Later on, it became the ancestor of the highest rulers and symbolized the absolute authority of a feudal emperor. The emperor claimed to be the son of the dragon. All of his personal possessions carried the name "dragon" and were decorated with various dragon figures. Now dragon decorations can be seen everywhere in China and legends about dragons circulate.''

Svend Nielsen has found no significant correlation between the number of Esperanto speakers and the similarity of a given national native language to Esperanto. He concludes that Esperanto tends to be more popular in rich countries with widespread Internet access and a tendency to contribute more to science and culture.

In the Almanac, his estimates for numbers of language speakers were rounded to the nearest million, thus the number of Esperanto speakers is shown as two million. This latter figure appears in ''

Though there are undoubtedly many Esperanto speakers who are not members of any Esperanto organization, he thinks it unlikely that there are fifty times more speakers than organization members.

Jouko Lindstedt, an expert on native-born Esperanto speakers, presented the following scheme
[Lindstedt, Jouko. "Re: " (posting)]
DENASK-L@helsinki.fi
, April 22, 1996. to show the overall proportions of language capabilities within the Esperanto community:
* 1,000 have Esperanto as their native family language.
* 10,000 speak it fluently.
* 100,000 can use it actively.
* One million understand a large amount passively.
* Ten million have studied it to some extent at some time.
In 2017, doctoral student Svend Nielsen estimated around 63,000 Esperanto speakers worldwide, taking into account association memberships, user-generated data from Esperanto websites and census statistics. This number, however, was disputed by statistician Sten Johansson, who questioned the reliability of the source data and highlighted a wide margin of error, the latter point with which Nielsen agrees. Both have stated, however, that this new number is likely more realistic than some earlier projections.
In the absence of Dr. Culbert's detailed sampling data, or any other census data, it is impossible to state the number of speakers with certainty. According to the website of the
Universal Esperanto Association:

s sold and membership of local societies put "the number of people with some knowledge of the language in the hundreds of thousands and possibly millions".
Native speakers
Native Esperanto speakers, , have learned the language from birth from Esperanto-speaking parents.
This usually happens when Esperanto is the chief or only common language in an international family, but sometimes occurs in a family of Esperanto speakers who often use the language. The 15th edition of ''Ethnologue'' cited estimates that there were 200 to 2,000 native speakers in 1996, but these figures were removed from the 16th and 17th editions. The 2019 online version of ''Ethnologue'' gives "L1 users: 1,000 (Corsetti et al 2004)". As of 1996, there were approximately 350 attested cases of families with native Esperanto speakers (which means there were around 700 Esperanto speaking natives in these families, not accounting for older native speakers).
However, native speakers do not occupy an authoritative position in the Esperanto community, as they would in other language communities. This presents a challenge to linguists, whose usual source of grammaticality and meanings are native speakers.

Popular culture
In the futuristic novel ''
Lord of the World'' by Robert Hugh Benson, Esperanto is presented as the predominant language of the world, much as Latin is the language of the Church. A reference to Esperanto appears in the science-fiction story ''
War with the Newts'' by Karel Čapek, published in 1936. As part of a passage on what language the salamander-looking creatures with human cognitive ability should learn, it is noted that "...in the Reform schools, Esperanto was taught as the medium of communication." (P. 206).
Esperanto has been used in many films and novels. Typically, this is done either to add the exotic flavour of a foreign language without representing any particular ethnicity, or to avoid going to the trouble of inventing a new language. The

Goals of the movement
Zamenhof had three goals, as he wrote already in 1887: to create an easy language, to create a language ready to use "whether the language be universally accepted or not" and to find some means to get many people to learn the language.
So Zamenhof's intention was not only to create an easy-to-learn language to foster peace and international understanding as a general language, but also to create a language for immediate use by a (small) language community. Esperanto was to serve as an international auxiliary language, that is, as a universal second language, not to replace ethnic languages. This goal was shared by Zamenhof among Esperanto speakers at the beginning of the movement. Later, Esperanto speakers began to see the language and the culture that had grown up around it as ends in themselves, even if Esperanto is never adopted by the United Nations or other international organizations.
Esperanto speakers who want to see Esperanto adopted officially or on a large scale worldwide are commonly called , from , meaning "final victory".
It has to be noted that there are two kinds of "finvenkismo"–"desubismo" and "desuprismo"; the first aims to spread Esperanto between ordinary people ("desube", from below) aiming to form a steadily growing community of Esperanto speakers. The second aims to act from above ("desupre"), beginning with politicians. Zamenhof considered the first way to have a better perspective, as "for such affairs as ours, governments come with their approval and help usually only, when everything is already finished".
Those who focus on the intrinsic value of the language are commonly called , from
Rauma, Finland, where a declaration on the short-term improbability of the and the value of Esperanto culture was made at the International Youth Congress in 1980.
However the "Manifesto de Raŭmo" clearly mentions the intention to further spread the language: "We want to spread Esperanto to put into effect its positive values more and more, step by step".
In 1996 the
Prague Manifesto was adopted at the annual congress of the Universal Esperanto Association (UEA); it was subscribed by individual participants and later by other Esperanto speakers. More recently, language-learning apps like
Duolingo and
Amikumu have helped to increase the amount of fluent speakers of Esperanto, and find others in their area to speak the language with.
Symbols and flags
The earliest flag, and the one most commonly used today, features a green five-pointed star against a white
canton, upon a field of green. It was proposed to Zamenhof by
Richard Geoghegan, author of the first Esperanto textbook for English speakers, in 1887. The flag was approved in 1905 by delegates to the first conference of Esperantists at Boulogne-sur-Mer.
The green star on white (') is also used by itself as a round (buttonhole, etc.) emblem by many esperantists, among other reasons to enhance their visibility outside the Esperanto world.
A version with an "" superimposed over the green star is sometimes seen. Other variants include that for Christian Esperantists, with a white
Christian cross superimposed upon the green star, and that for Leftists, with
the color of the field changed from green to red.
In 1987, a second flag design was chosen in a contest organized by the UEA celebrating the first centennial of the language. It featured a white background with two stylised curved "E"s facing each other. Dubbed the "" (
jubilee symbol), it attracted criticism from some Esperantists, who dubbed it the "" (melon) because of the design's elliptical shape. It is still in use, though to a lesser degree than the traditional symbol, known as the "" (green star).

`Abdu'l-Bahá praised the ideal of Esperanto, and there was an affinity between Esperantists and Baháʼís during the late 19th century and early 20th century.
On February 12, 1913, `Abdu'l-Bahá gave a talk to the Paris Esperanto Society, stating:
Now, praise be to God that Dr. Zamenhof has invented the Esperanto language. It has all the potential qualities of becoming the international means of communication. All of us must be grateful and thankful to him for this noble effort; for in this way he has served his fellowmen well. With untiring effort and self-sacrifice on the part of its devotees Esperanto will become universal. Therefore every one of us must study this language and spread it as far as possible so that day by day it may receive a broader recognition, be accepted by all nations and governments of the world, and become a part of the curriculum in all the public schools. I hope that Esperanto will be adopted as the language of all the future international conferences and congresses, so that all people need acquire only two languages—one their own tongue and the other the international language. Then perfect union will be established between all the people of the world. Consider how difficult it is today to communicate with various nations. If one studies fifty languages one may yet travel through a country and not know the language. Therefore I hope that you will make the utmost effort, so that this language of Esperanto may be widely spread.
Lidia Zamenhof, daughter of L. L. Zamenhof, became a Baháʼí around 1925.

movement, a fact which disenfranchised liberal and Jewish members, thus severely limiting the growth of the KELI during the first half of the 20th century.
KELI's bimonthly interdenominational magazine, ''Dia Regno'', continues to be published and is reportedly made available to readers in 48 countries. They have also published several Esperanto hymnals including the 1971 ''Adoru Kantante'' (Worship by Singing) and ''Tero kaj Ĉielo Kantu'' (Earth and Heaven Sing).

Modifications
Though Esperanto itself has changed little since the publication of (''Foundation of Esperanto''), a number of reform projects have been proposed over the years, starting with
Zamenhof's proposals in 1894 and in 1907. Several later constructed languages, such as
Universal,
Saussure, Romániço,
Internasia,
Esperanto sen Fleksio, and Mundolingvo, were all based on Esperanto.
In modern times, conscious attempts have been made to eliminate perceived sexism in the language, such as
Riism. Many words with now have alternative spellings with and occasionally , so that may also be spelled ; see
Esperanto phonology for further details of replacement. Reforms aimed at altering country names have also resulted in a number of different options, either due to disputes over suffixes or Eurocentrism in naming various countries.
Criticism
There have been numerous objections to Esperanto over the years. For example, there has been criticism that Esperanto is not neutral enough, but also that it should convey a specific culture, which would make it less neutral; that Esperanto does not draw on a wide enough selection of the world's languages, but also that it should be more narrowly European.
Language-neutrality
Esperantists often argue for Esperanto as a culturally neutral means of communication. However, it is often accused of being

is arguably more European than not. Supporters have argued that the agglutinative grammar and verb regularity of Esperanto has more in common with Asian languages than with European ones. A 2010 typological study concluded that "Esperanto is indeed somewhat European in character, but considerably less so than the European languages themselves."
Critics argue that a truly neutral language would draw its vocabulary from a much wider variety of languages, so as not to give an unfair advantage to speakers of any of them. Although a truly representative sampling of the world's thousands of languages would be unworkable, a derivation from, e.g. the Romance, Germanic,
Semitic,
Indo-Aryan,
Bantu, and
Sino-Tibetan language families would strike many as being fairer than Esperanto-like solutions, as these families cover about 60% of the world's population, compared to a fifth for Romance and Germanic.
Gender-neutrality

sexist

, because the default form of some nouns is masculine while a derived form is used for the feminine, which is said to retain traces of the male-dominated society of late 19th-century Europe of which Esperanto is a product.
[Bertilo](_blank)
(in Esperanto) These nouns are primarily titles and kin terms, such as ''sinjoro'' "Mr, sir" vs. ''sinjorino'' "Ms, lady" and ''patro'' "father" vs. ''patrino'' "mother". In addition, nouns that denote persons and whose definitions are not explicitly male are often assumed to be male unless explicitly made female, such as ''doktoro,'' a PhD doctor (male or unspecified) versus ''doktorino,'' a female PhD. This is analogous to the situation with the English suffix ''-ess,'' as in the words ''baron/baroness'', ''waiter/waitress'', etc. On the other hand, the pronoun ''ĝi'' ("it") may be used generically to mean he/she/they; the pronoun ''li'' ("he") is always masculine and ''ŝi'' ("she") is always female, despite some authors' arguments.

forms of the plural (nouns in ''-oj,'' adjectives in ''-aj)'' to be awkward, proposing instead that Italian ''-i'' be used for nouns, and that no plural be used for adjectives. These suggestions were adopted by the
Ido reform.
A reply to that criticism is that the presence of an accusative case allows much freedom in word order, e.g. for emphasis ("Johano batis Petron", John hit Peter; "Petron batis Johano", it is Peter whom John hit), that its absence in the "predicate of the object" avoids ambiguity ("Mi vidis la blankan domon", I saw the white house; "Mi vidis la domon blanka", the house seemed white to me) and that adjective agreement allows, among others, the use of
hyperbaton in poetry (as in Latin, cf. Virgil's

1:1 ''Tityre, tu
patulæ recubans sub tegmine
fagi…'' where "patulæ" (spread out) is epithet to "fagi" (beech) and their agreement in the genitive feminine binds them notwithstanding their distance in the verse).
Alphabet
The Esperanto alphabet uses two diacritics: the circumflex and the breve. The alphabet was designed with a French typewriter in mind, and although modern computers support Unicode, entering the letters with diacritic marks can be more or less problematic with certain operating systems or hardware. One of the first reform proposals (for
Esperanto 1894) sought to do away with these marks and the language
Ido went back to the basic Latin alphabet.
Achievement of its creator's goals
One common criticism is that Esperanto has failed to live up to the hopes of its creator, who dreamed of it becoming a universal second language.
[Saul Levin, 1993. "Can an Artificial Language Be More than a Hobby? The Linguistic and Sociological Obstacles". In Ian Richmond (ed.) ''Aspects of internationalism: language & culture''.][''The Christian Century'', 1930, 47:846] Because people were reluctant to learn a new language which hardly anyone spoke, Zamenhof asked people to sign a promise to start learning Esperanto once ten million people made the same promise. He "was disappointed to receive only a thousand responses."
However, Zamenhof had the goal to "enable the learner to make direct use of his knowledge with persons of any nationality, whether the language be universally accepted or not",
as he wrote in 1887. The language is currently spoken by people living in more than 100 countries; there are about 2,000 native Esperanto speakers and probably up to 100,000 people who use the language regularly.
In this regard, Zamenhof was well aware that it might take much time for Esperanto to achieve his desired goals. In his speech at the 1907
World Esperanto Congress in

he said, "we hope that earlier or later, maybe after many centuries, on a neutral language foundation, understanding one another, the nations will build ... a big family circle."
The poet
Wisława Szymborska expressed doubt that Esperanto could "produce works of lasting value," saying it is "an artificial language without variety or dialects" and that "no one thinks in Esperanto." Esperantists have replied that "lasting value" is a statement of opinion, that Esperanto grew "naturally" by the actions of its speakers on Zamenhof's intentionally elementary ''Fundamento'', and that the last sentence ("No one thinks in Esperanto") is false-to-fact.

John Ronald Reuel Tolkien (, ; 3 January 1892 – 2 September 1973) was an English writer and philologist. He was the author of the high fantasy works ''The Hobbit'' and ''The Lord of the Rings''.

wrote in support of the language in a 1932 ''British Esperantist'' article, but criticised those who
sought to adapt or "tinker" with the language, which, in his opinion, harmed unanimity and the goal of achieving wide acceptance.
