Edgar de WahlEdgar Alexei Robert von Wahl (Interlingue: Edgar de Wahl; 23 August 1867 – 9 March 1948) was a Baltic German mathematics and physics teacher who lived in Tallinn, Estonia. He is best known as the creator of Interlingue, an international auxiliary language that was known as Occidental throughout his life. A Baltic German, De Wahl was born, raised and lived most of his life in the Russian Empire. Born in the territory of today's Ukraine, he spent his childhood in Tallinn and Saint Petersburg.
Fictional languageFictional languages are the subset of constructed languages (conlangs) that have been created as part of a fictional setting (e.g. for use in a book, movie, television show, or video game). Typically they are the creation of one individual, while natural languages evolve out of a particular culture or people group, and other conlangs may have group involvement. Fictional languages are also distinct from natural languages in that they have no native speakers. By contrast, the constructed language of Esperanto now has native speakers.
Louis CouturatLouis Couturat (kutyʁa; 17 January 1868 – 3 August 1914) was a French logician, mathematician, philosopher, and linguist. Couturat was a pioneer of the constructed language Ido. Born in Ris-Orangis, Essonne, France. In 1887 he entered École Normale Supérieure to study philosophy and mathematics. In 1895 he lectured in philosophy at the University of Toulouse and 1897 lectured in philosophy of mathematics at the University of Caen Normandy, taking a stand in favor of transfinite numbers.
Universal languageUniversal language may refer to a hypothetical or historical language spoken and understood by all or most of the world's people. In some contexts, it refers to a means of communication said to be understood by all humans. It may be the idea of an international auxiliary language for communication between groups speaking different primary languages. In other conceptions, it may be the primary language of all speakers, or the only existing language.
Toki PonaToki Pona (rendered as toki pona and often translated as 'the language of good'; ˈtoki ˈpona ; ˈtoʊki_ˈpoʊnə) is a philosophical artistic constructed language (philosophical artlang) known for its small vocabulary, simplicity, and ease of acquisition. It was created by Sonja Lang, a Canadian linguist and translator, to simplify thoughts and communication. The first drafts were published online in 2001, while the complete form was published in the book Toki Pona: The Language of Good in 2014.
IdoIdo (ˈiːdoʊ) 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 (and, above all, easy to learn and use). It is the most successful of the many Esperanto derivatives, called Esperantidoj.
InterlinguaInterlingua (ɪntərˈlɪŋɡwə; ISO 639 language codes ia, ina) is an international auxiliary language (IAL) developed between 1937 and 1951 by the American International Auxiliary Language Association (IALA). It ranks among the most widely used IALs and is the most widely used naturalistic IAL – in other words, those IALs whose vocabulary, grammar, and other characteristics are derived from natural languages, rather than being centrally planned.
World languageA world language (sometimes global language, rarely international language) is a language that is geographically widespread and makes it possible for members of different language communities to communicate. The term may also be used to refer to constructed international auxiliary languages such as Esperanto. English is the foremost—and by some accounts the only—world language. Beyond that, there is no academic consensus about which languages qualify; Arabic, French, Russian, and Spanish are other possible world languages.
IthkuilIthkuil 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.
Klingon languageThe Klingon language (tlhIngan Hol, : , ˈt͡ɬɪ.ŋɑn xol) is the constructed language spoken by a fictional alien race called the Klingons, in the Star Trek universe. Described in the 1985 book The Klingon Dictionary by Marc Okrand and deliberately designed to sound "alien", it has a number of typologically uncommon features. The language's basic sound, along with a few words, was devised by actor James Doohan ("Scotty") and producer Jon Povill for Star Trek: The Motion Picture. That film marked the first time the language had been heard.
