Esperanto is the world's most widely spoken constructed international auxiliary language. Created by L. L. Zamenhof in 1887, it is intended to be a universal second language for international communication, or "the international language". Zamenhof first described the language in Dr. Esperanto's International Language, which he published under the pseudonym Doktoro Esperanto. Early adopters of the language liked the name Esperanto and soon used it to describe his language. The word esperanto translates into English as "one who hopes".
Esperanto is the most widely used constructed language intended for international communication; it was designed with highly regular grammatical rules, and as such is considered an easy language to learn.
Ido is a constructed language derived from Reformed Esperanto, and similarly designed with the goal of being a universal second language for people of diverse backgrounds. To function as an effective international auxiliary language, Ido was specifically designed to be grammatically, orthographically, and lexicographically regular. It is the most successful of the many Esperanto derivatives, called Esperantidoj.
Novial is a constructed international auxiliary language (IAL) for universal human communication between speakers of different native languages. It was devised by Otto Jespersen, a Danish linguist who had been involved in the Ido movement that evolved from Esperanto at the beginning of the 20th century, and participated later in the development of Interlingua. The name means 'new' + 'international auxiliary language'.
Native Esperanto speakers are people who have acquired Esperanto as one of their native languages. As of 1996, there were 350 or so attested cases of families with native Esperanto speakers. Estimates from associations indicate that there were around 1,000 Esperanto-speaking families, involving perhaps 2,000 children in 2004. According to a 2019 synthesis of all the estimates made, they would be between several hundred and 2000, and would compose between <1% and 4.5% of the Esperanto community. In all known cases, speakers are natively bilingual, or multilingual, raised in both Esperanto and either the local national language or the native language of their parents. In all but a handful of cases, it was the father who used Esperanto with the child. In the majority of such families, the parents had the same native language, though in many the parents had different native languages, and only Esperanto in common.
Esperanto is written in a Latin-script alphabet of twenty-eight letters, with upper and lower case. This is supplemented by punctuation marks and by various logograms, such as the digits 0–9, currency signs such as $ € ¥ £ ₷, and mathematical symbols. The creator of Esperanto, L. L. Zamenhof, declared a principle of "one letter, one sound", though this is a general rather than strict guideline.
Proto-Esperanto is the modern term for any of the stages in the evolution of L. L. Zamenhof's language project, prior to the publication of Unua Libro in 1887.
Catalan grammar, the morphology and syntax of the Catalan language, is similar to the grammar of most other Romance languages. Catalan is a relatively synthetic, fusional language. Features include:
This article discusses the forms and functions of the personal pronouns in Catalan grammar.
A limited number of Esperanto adverbs do not end with the regular adverbial ending -e. Many of them function as more than just adverbs, such as hodiaŭ "today" and ankoraŭ "yet" or "still". Others are part of the correlative system, and will not be repeated here.
Gender asymmetry is an aspect of the constructed international auxiliary language Esperanto which has been challenged by numerous proposals seeking to regularize both grammatical and lexical gender.
The original word base of Esperanto contained around 900 root words and was defined in Unua Libro, published by L. L. Zamenhof in 1887. In 1894, Zamenhof published the first Esperanto dictionary, Universala vortaro, which was written in five languages and supplied a larger set of root words, adding 1740 new words.
An Esperantido is a constructed language derived from Esperanto. Esperantido originally referred to the language which is now known as Ido. The word Esperantido contains the affix (-ido), which means a "child, young or offspring". Hence, Esperantido literally means an 'offspring or descendant of Esperanto'.
Esperanto II or Esperanto 2 was a reform of Esperanto proposed by René de Saussure in 1937, the last of a long series of such proposals beginning with a 1907 response to Ido with a project called Lingwo Internaciona, later called Antido 1. Esperanto II was one of several languages investigated by the International Auxiliary Language Association, the linguistic research body that eventually standardized and presented Interlingua de IALA.
Arcaicam Esperantom, is an auxiliary sociolect for translating literature into Esperanto created to act as a fictional 'Old Esperanto', in the vein of languages such as Middle English or the use of Latin citations in modern texts.
Reformed Esperanto, or Esperanto 1894, is a constructed language derived from Esperanto, created by the original creator of Esperanto. It is notable as the only complete Esperantido by L. L. Zamenhof. Pressured to address proposed reforms after some six years, the project was eventually rejected by the majority and even Zamenhof himself later. However, some of the proposed reforms were used in the language Ido, beginning in 1907, and live on in that language.
Adjuvilo is a constructed language created in 1910 by Claudius Colas under the pseudonym of "Profesoro V. Esperema". Although it was a full language, it may not have been created to be spoken. Many believe that as an Esperantist, Colas created Adjuvilo to help create dissent in the then-growing Ido movement. Colas himself called his language simplified Ido and proposed several reforms to Ido.

Intal is an international auxiliary language, published in 1956 by the German linguist Erich Weferling. Its name is an acronym for INTernational Auxiliary Language. Intal was conceived to unite the most important features of existing international auxiliary languages, like Esperanto, Ido, Occidental-Interlingue, Neo, Novial and Interlingua, into a compromise system.
