Constructed languages

Esperanto () is the world's most widely spoken constructed auxiliary language. Created by L. L. Zamenhof in 1887 as "the International Language" (), it is intended to be a universal second language for international communication. He described the language in ''Dr. Esperanto's International Language'' (known as , the "first book"), which he published under the pseudonym . Early adopters of the language liked the name and soon used it to describe his language. The word translates into English as "one who hopes".

Interlingue (; ISO 639 ie, ile), originally Occidental (), is an international auxiliary language created in 1922 and renamed in 1949.

The vocabulary is based on pre-existing words from various languages and a derivational system which uses recognized prefixes and suffixes.

Interlingua (, ) is an international auxiliary language (IAL) developed between 1937 and 1951 by the American International Auxiliary Language Association (IALA). It is a constructed language of the "naturalistic" variety, whose vocabulary, grammar, and other characteristics are derived from natural languages. Interlingua literature maintains that (written) Interlingua is comprehensible to the billions of people who speak Romance languages, though it is actively spoken by only a few hundred.

Ido () is a constructed language derived from a reformed version of Esperanto, and designed similarly with the goal of being an international auxiliary language (or universal second language) for people of diverse languages. To function as an effective international auxiliary language, Ido was designed specifically to be grammatically, orthographically, and lexicographically regular (and, above all, easy to learn and use). It is the most successful of the many Esperanto derivatives, known as Esperantidoj.

Volapük (; , 'Language of the World', or ) is a constructed language created in 1879 and 1880 by Johann Martin Schleyer, a Roman Catholic priest in Baden, Germany.

Its grammar is inspired largely by German, although it was heavily regularized by Schleyer, while its lexicon is rooted mostly in English, with additional influence from German, the Romance languages, and Russian. Despite some roots remaining recognizable, many words were altered beyond recognition, as Schleyer sought

Ithkuil is an experimental constructed language created by John Quijada. It is designed to express more profound levels of human cognition briefly yet overtly and clearly, particularly about human categorization. It is a cross between an a priori philosophical and a logical language. It tries to minimize the vagueness and semantic ambiguity in natural human languages. Ithkuil is notable for its grammatical complexity and extensive phoneme inventory, the latter being simplified in an upcoming redesign. The name "Ithkuil" is an anglicized form of Iţkuîl, which in the original form roughly meant

Loglan is a logical constructed language originally designed for linguistic research, particularly for investigating the Sapir–Whorf hypothesis. The language was developed beginning in 1955 by Dr. James Cooke Brown with the goal of making a language so different from natural languages that people learning it would think in a different way if the hypothesis were true. In 1960, Scientific American published an article introducing the language. Loglan is the first among, and the main inspiration for, the languages known as logical languages, which also includes Lojban.

The word Esperantido contains the affix (-ido), which means a "child (born to a parent), young (of an animal) or offspring".

Europanto is a macaronic language concept with a fluid vocabulary from European languages of the user's choice or need. It was conceived in 1996 by Diego Marani (a journalist, author and translator for the European Council of Ministers in Brussels) based on the common practice of word-borrowing usage of many European languages. Marani used it in response to the perceived dominance of the English language; it is an emulation of the effect that non-native speakers struggling to learn a language typically add words and phrases from their native language to express their meanings clearly.
