Constructed languageA constructed language (shortened to a conlang) is a language whose phonology, grammar, and vocabulary, instead of having developed naturally, are consciously devised for some purpose, which may include being devised for a work of fiction. A constructed language may also be referred to as an artificial, planned or invented language, or (in some cases) a fictional language. Planned languages (or engineered languages/engelangs) are languages that have been purposefully designed; they are the result of deliberate, controlling intervention and are thus of a form of language planning.
NovialNovial 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'. Its vocabulary is based largely on the Germanic and Romance languages while its grammar is influenced by English.
Native Esperanto speakersNative Esperanto speakers (Esperanto: denaskuloj or denaskaj esperantistoj) 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
InterlingueInterlingue (interˈliŋɡwe; ISO 639 ie, ile), originally Occidental (oktsidenˈtaːl), is an international auxiliary language created in 1922 and renamed in 1949. Its creator, Edgar de Wahl, sought to achieve maximal grammatical regularity and natural character. The vocabulary is based on pre-existing words from various languages and a derivational system which uses recognized prefixes and suffixes. Many of Interlingue's derived word forms reflect those common to certain Western European languages, primarily the Romance languages, along with some Germanic vocabulary.
VolapükVolapük (ˈvɒləpʊk; volaˈpyk, "Language of the World", or lit. "World Speak") is a constructed language created between 1879 and 1880 by Johann Martin Schleyer, a Catholic priest in Baden, Germany, who believed that God had told him in a dream to create an international language. Notable as the first major constructed international auxiliary language, the grammar comes from European languages and the vocabulary mostly from English (with some German and French). However, the roots are often distorted beyond recognition.
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.
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.
EsperantoEsperanto (ˌɛspəˈrɑːntoʊ or ˌɛspəˈræntoʊ) is the world's most widely spoken constructed international auxiliary language. Created by the Warsaw-based ophthalmologist L. L. Zamenhof in 1887, it is intended to be a universal second language for international communication, or "the international language" (la Lingvo Internacia). Zamenhof first described the language in Dr. Esperanto's International Language (Unua Libro), which he published under the pseudonym Doktoro Esperanto.
Natural languageIn neuropsychology, linguistics, and philosophy of language, a natural language or ordinary language is any language that occurs naturally in a human community by a process of use, repetition, and change without conscious planning or premeditation. It can take different forms, namely either a spoken language or a sign language. Natural languages are distinguished from constructed and formal languages such as those used to program computers or to study logic. Natural language can be broadly defined as different from artificial and constructed languages, e.
International EnglishInternational English is the concept of using the English language as a global means of communication similar to an international auxiliary language, and often refers to the movement towards an international standard for the language. Related and sometimes synonymous terms include: Global English, World English, Common English, Continental English, General English, and Engas (English as associate language). Sometimes, these terms refer to the actuality of the situation, where English is spoken and used in numerous dialects around the world.
