La Portalo pri Esperanto

The Esperanto flag.

Esperanto is the most widely spoken constructed international auxiliary language in the world. Its name derives from Doktoro Esperanto, the pseudonym under which L. L. Zamenhof published the first book detailing Esperanto, the Unua Libro, in 1887. The word esperanto means 'one who hopes' in the language itself. Zamenhof's goal was to create an easy and flexible language that would serve as a universal second language to foster peace and international understanding.

Esperanto has had continuous usage for over a century by a community now estimated at about 2 million speakers, and approximately one thousand native speakers. However, no country has adopted the language officially. Today, Esperanto is employed in world travel, correspondence, cultural exchange, conventions, literature, language instruction, television, and radio broadcasting. Also, there is an Esperanto Wikipedia with over 238,500 articles (as of April 15, 2017). Over 150,000 users now consult the Esperanto Wikipedia regularly.

There is evidence that learning Esperanto may provide a good foundation for learning languages in general. Some state education systems offer basic instruction and elective courses in Esperanto. Esperanto is also the language of instruction in one university, the Akademio Internacia de la Sciencoj in San Marino.

Free on-line courses to teach the international language are available through lernu.net and duolingo.com. The first of these sites has nearly 244,000 registered users, who are able to view the site's interface in their choice of 17 languages; a further six languages have at least 60 percent of the interface localized. About 50,000 of the lernu.net users possess a basic, intermediate or advanced understanding of Esperanto. On March 25, 2016, when the Duolingo Esperanto course completed its beta-testing phase, that course had 350,000 people registered to learn Esperanto through the medium of English; in the subsequent year, the number of learners has more than doubled and now stands at 812,000.

Duolingo has developed a second Esperanto course for which the language of instruction is Spanish; public beta testing began in October of 2016. Over 96,000 students are currently beta-testing this course. A third Esperanto course, this one to be taught in Brazilian Portuguese, has begun development and is expected to be released to beta testing by the end of 2017.

The italic spesmilo sign for the obsolete Esperanto currency, a ligature of S and m.

Esperanto is written in a Latin alphabet of twenty-eight letters, with upper and lower case. This is supplemented by punctuation marks and by various logograms, such as the numerals 0–9, currency signs such as $, and mathematical symbols.

Twenty-two of the letters are identical in form to letters of the English alphabet (q, w, x, and y being omitted). The remaining six have diacritic marks, ĉ, ĝ, ĥ, ĵ, ŝ, and ŭ (that is, c, g, h, j, and s circumflex, and u breve). Find out more...

In Esperanto, numbers can be compounded or derived to form larger numbers or related concepts. For example, dudek = "twenty" is made from the words du = "two" and dek = "ten." Likewise, dek du = "twelve" is created from the same numbers, but the different order results in a different number. In the same way, ducent = "two hundred" (from the words du = "two" and cent = "hundred"), while cent du = "one hundred two" and cent dudek = "one hundred twenty." Also, numbers can be combined with other suffixes to form derivatives like tria = "third" (adding the adjective suffix -a), trie = "thirdly" (with the adverb suffix -e instead), triono = "one-third" (adding the noun suffix -ono to create a fraction), triopo = "trio" or "triad" (adding the noun suffix -opo to make a group of three) and triobla = "threefold" (adding the adjective suffix -obla).
