Esperanto FAQ: 31 questions answered with facts

These are the questions people most often type into search engines or ask AI assistants about Esperanto. Each answer is short; follow the links for details and sources.

#The basics

#What is Esperanto?

Esperanto is a constructed language designed for international communication. L. L. Zamenhof published it in Warsaw in 1887 to give people of different countries an easy, neutral second language. It has regular grammar, phonetic spelling and a vocabulary drawn mainly from European languages. See about Esperanto.

#Is Esperanto a real language?

Yes: it has a fixed grammar, a large vocabulary, an estimated 1,000–2,000 native speakers, published writing since the Unua Libro of 1887, which already contained poems and translations, and a world congress held almost every year since 1905. It has its own ISO 639-1 code (eo) and ISO 639-3 code (epo, type "constructed"), and its Wikipedia has nearly 390,000 articles (October 2026). What sets it apart from natural languages is its origin – it was designed, then adopted by a community – not its status. See native speakers.

#What language is Esperanto based on?

No single language. Most roots come from Latin and the Romance languages (French, Italian), about a quarter from Germanic languages (German, English, Yiddish), and a few percent from Slavic, Greek and others, while the grammar is Esperanto's own regular system. In our analysis of the 1,000 most frequent roots, 69% were Romance, 24% Germanic and 4% Slavic. See what Esperanto is based on.

#Who invented Esperanto?

Ludwik Lejzer Zamenhof (1859–1917), an eye doctor from Białystok, then in the Russian Empire and now in Poland. He grew up among speakers of Yiddish, Russian, Polish and German and believed a shared neutral language could reduce conflict. Read his biography.

#When was Esperanto created?

The first textbook, the Unua Libro, was published in Warsaw on 26 July 1887. Zamenhof had worked on the language since the 1870s and showed a first draft to friends in December 1878. See the history of Esperanto.

#What does "Esperanto" mean?

"One who hopes". Zamenhof published his first book under the pen name Doktoro Esperanto – "Doctor Hopeful" – and early users soon called the language by that name. Its official name was Lingvo Internacia, "International Language".

#What does the Esperanto flag look like?

It is green with a white square in the upper corner containing a green five-pointed star. Green stands for hope, white for peace and the star's five points for the five continents. It was adopted in 1905. See flag and symbols.

#Speakers and status

#How many people speak Esperanto?

Nobody knows exactly, because no census covers all speakers. Serious estimates range from about 60,000 (Nielsen, 2017) to about 2 million (Culbert; Wandel, 2015). See how many people speak Esperanto for every estimate and its method.

#Does Esperanto have native speakers?

Yes, an estimated 1,000–2,000. They grow up with at least one parent who speaks Esperanto to them, sometimes because it is the parents' only common language. See native speakers.

#Is Esperanto an official language anywhere?

No. No country or region uses Esperanto as an official language. UNESCO adopted resolutions supporting it in 1954 and 1985, and the Universal Esperanto Association has official relations with UNESCO (since 1954) and special consultative status with the UN's Economic and Social Council (since 1998).

#Where do people speak Esperanto?

Everywhere and nowhere in particular: speakers live in more than 120 countries. The largest organised communities are in Europe (especially France and Germany), Brazil, the United States and East Asia (especially Japan), with growing groups in Africa. See where Esperanto is spoken.

#Is Esperanto dead?

No. It has an active community, a congress held almost every year since 1905, new books and music, and one of the 40 largest Wikipedias, with about 390,000 articles in 2026. Millions have started learning it online since 2015. It is small, but it is used every day.

#Why didn't Esperanto become the world language?

Mostly politics, not grammar. Governments never adopted it: France blocked a League of Nations proposal in the early 1920s, the Nazi and Soviet regimes persecuted its speakers, and after 1945 English spread with American economic power. See the history and criticism pages.

#What is the point of Esperanto?

To give people with different native languages a neutral, easy common language, so that nobody has to give way to another's mother tongue – Zamenhof's aim in 1887. Today speakers use it mainly to meet and write to people in other countries, at congresses, through Pasporta Servo hosting and in books and music, rather than for business. Its regular grammar and phonetic spelling make it quick to learn, but it has not replaced English as the world's default second language. See is Esperanto dead? for the size of the community.

#What is the World Esperanto Congress?

The main yearly meeting of Esperanto speakers, held since 1905 in a different city each year (in 2020 and 2021 it was replaced by online congresses). Recent congresses have drawn about 850–1,300 participants; the record was 5,946 in Warsaw in 1987. The 2026 congress met in Graz, Austria, and 2027 is planned for Melbourne. See World Congress.

#Learning Esperanto

#Is Esperanto easy to learn?

For most people it is much easier than a national language. Spelling is phonetic, there are no irregular verbs, and word-building lets you make many words from one root. How long it takes depends on your native language and practice; see how long it takes to learn Esperanto.

#Is Esperanto worth learning?

It depends on your goal. Esperanto will not help in business like English or Chinese, but it gives access to an international community, free hosting through Pasporta Servo, congresses and a culture of its own. Some studies suggest it can make later language learning easier, although the evidence is debated. See how to learn Esperanto.

#Can I learn Esperanto on Duolingo?

Yes. Duolingo launched a beta Esperanto course for English speakers on 28 May 2015; versions for Spanish (2016), Portuguese (2018) and French (2020) speakers followed. By March 2020, 2.8 million people had started the English-, Spanish- and Portuguese-based courses. Other free options are listed in learning resources.

#Does Google Translate support Esperanto?

Yes. Google Translate added Esperanto on 22 February 2012 as its 64th language. The Google team was surprised by the quality despite little training data and suggested that a language designed to be easy for humans to learn seems to help machine translation too.

#How do I type the Esperanto letters ĉ, ĝ, ĥ, ĵ, ŝ, ŭ?

Use an Esperanto keyboard layout, or type the "x-system" (cx, gx, sx…): the search and the typing exercises on this site understand it. The alphabet page explains both ways.

#How many words does Esperanto have?

The main monolingual dictionary, the Plena Ilustrita Vortaro (2002 edition), has 16,780 headwords – mostly roots – and 46,890 lexical units. Because roots combine freely with prefixes and suffixes, speakers can form many more words than any dictionary lists. See Esperanto vocabulary.

#Culture and debate

#Is Esperanto Eurocentric?

Its vocabulary is largely European – mostly from Romance and Germanic languages, with Slavic, Greek and other elements. Its grammar, however, works by gluing unchanging parts together, which resembles languages like Chinese, Turkish or Swahili. Critics and supporters weigh this differently; see criticism of Esperanto.

#Is Esperanto sexist?

Many basic nouns are masculine or neutral by default and form the feminine with the suffix -in-, as in patro "father" and patrino "mother". Speakers have debated reforms such as the pronoun ri for "he or she"; usage is slowly changing. See criticism of Esperanto.

#Is there literature in Esperanto?

Yes. Estimates range from about 10,000 to more than 25,000 titles, including original novels and poetry and translations of the Bible, Shakespeare, Dante and The Lord of the Rings. See Esperanto literature.

#Are there films and music in Esperanto?

Yes. The best-known film is Incubus (1966), starring William Shatner. Music ranges from rock and hip-hop to folk, with labels such as Vinilkosmo. See music and film.

#Which famous people spoke Esperanto?

Documented examples include the writer Leo Tolstoy, who said he learned to read it within hours, the Nobel laureate Daniel Bovet, a native speaker, and the economist Reinhard Selten. See famous Esperanto speakers.

#How is Esperanto different from Ido, Volapük or Klingon?

Volapük (1879–80) came earlier, peaked around 1889 and declined sharply in the 1890s; Ido (1907) is a reform of Esperanto with a few hundred to a few thousand speakers; Klingon (1985) and Toki Pona (2001) were made for fiction or as a minimalist art language, not for world communication. See Esperanto compared.

#What is Zamenhof Day?

15 December, Zamenhof's birthday, is the most widely celebrated day among Esperanto speakers. It is also Esperanto Book Day, when people buy or give books in Esperanto. See Zamenhof Day.

#Is there an organisation for Esperanto speakers?

Yes. The Universal Esperanto Association (UEA), founded in 1908 and based in Rotterdam, is the largest. Its youth section is TEJO, and the Academy of Esperanto watches over the language. See Esperanto organisations.

#What are the 16 rules of Esperanto?

The original grammar in the Unua Libro (1887) was summarised in 16 short rules, covering endings, plurals, the accusative, verbs and stress. See the 16 rules of Esperanto grammar.

#How do you say "hello" in Esperanto?

Saluton! – "Hello!" To ask how someone is, say Kiel vi fartas? – "How are you?" See basic Esperanto phrases.
