International auxiliary language in the context of "Artistic languages"

An auxiliary language is one not the primary or native language of a community. It may refer to:

• Interlanguage, an idiolect that has been developed by a learner of a second language
• International auxiliary language, a planned language constructed for international communication, such as Esperanto or International Sign
• Zonal auxiliary language, a planned language focused on one particular region, often blending elements of somewhat related languages in that region
• Minority language, a secondary language that has official recognition
• Sacred language, also called liturgical language or initiation language, used in religious services
• Lingua franca, a language used to facilitate communication between groups without a common native language

A world language (sometimes called a global language or, rarely, an 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.

English is the foremost world language and, by some accounts, the only one. Other languages that can be considered world languages include Arabic, French, Russian, and Spanish, although there is no clear academic consensus on the subject. Some writers consider Latin to have formerly been a world language.

Zonal auxiliary languages, or zonal constructed languages, are constructed languages made to facilitate communication between speakers of a certain group of closely related languages. They form a subgroup of the international auxiliary languages but are intended to serve a limited linguistic or geographic area, rather than the whole world like Esperanto and Volapük. Although most zonal auxiliary languages are based on European language families, they should not be confused with "Euroclones", a pejorative term for languages intended for global use but based primarily on European material. Since universal acceptance is not the goal for zonal auxiliary languages, the traditional claims of neutrality and universalism, typical for IALs, do not apply. Although they may share the same internationalist commitments of the latter, zonal auxiliary languages have also been proposed as a defense against the effects of the growing hegemony of English on other cultures or as a means to promote a sense of ethnicity or community in a manner similar to revitalized languages, such as Modern Hebrew and Cornish. Related concepts are koiné language, a dialect that naturally emerges as a means of communication among speakers of divergent dialects of a language, and Dachsprache, a dialect that serves as a standard language for other, sometimes mutually unintelligible, dialects. The difference is that a zonal language is typically a mixture of several natural languages and is aimed to serve as an auxiliary for the speakers of different but related languages of the same family.

Most zonal constructed languages were developed during the period of romantic nationalism at the end of the 19th century, but some were created later. Most older zonal constructed languages are now known only to specialists. A modern example is Interslavic, which has become the most successful example of all zonal constructed languages.

Basic English (a backronym for British American Scientific International and Commercial English) is a controlled language based on standard English, but with a greatly simplified vocabulary and grammar. It was created by the linguist and philosopher Charles Kay Ogden as an international auxiliary language, and as an aid for teaching English as a second language. It was presented in Ogden's 1930 book Basic English: A General Introduction with Rules and Grammar.

The first work on Basic English was written by two Englishmen, Ivor Richards of Harvard University and Charles Kay Ogden of the University of Cambridge in England. The design of Basic English drew heavily on the semiotic theory put forward by Ogden and Richards in their 1923 book The Meaning of Meaning.

Esperanto (/ˌɛspəˈrɑːntoʊ, -ˈræntoʊ/) is the world's most widely spoken constructed international auxiliary language. Created by L. L. Zamenhof in 1887 to be 'the International Language' (la Lingvo Internacia), it is intended to be a universal second language for international communication. He described the language in Dr. Esperanto's International Language (Unua Libro), 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 translates into English as 'one who hopes'.

Within the range of constructed languages, Esperanto occupies a middle ground between "naturalistic" (imitating existing natural languages) and a priori (where features are not based on existing languages). Esperanto's vocabulary, syntax and semantics derive predominantly from languages of the Indo-European group. A substantial majority of its vocabulary (approximately 80%) derives from Romance languages, but it also contains elements derived from Germanic, Greek, and Slavic languages. One of the language's most notable features is its extensive system of derivation, where prefixes and suffixes may be freely combined with roots to generate words, making it possible to communicate effectively with a smaller set of words.

Ido (/ˈiːdoʊ/) is a constructed language derived from a reformed version of Esperanto, and designed similarly with the goal of being a 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.

Ido was created in 1907 due to a desire to reform the perceived flaws of Esperanto, a language that had been created 20 years earlier to facilitate international communication. The name comes from the Esperanto word ido, meaning "offspring", since the language is a derivative of Esperanto. After its inception, Ido was endorsed by some of the Esperanto community. A setback occurred with the sudden death in 1914 of one of its most influential proponents, Louis Couturat. In 1928, promoter Otto Jespersen quit the movement for his own language Novial.

Interlingua (/ɪntərˈlɪŋɡwə/, Interlingua: [inteɾˈliŋɡwa]) 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.

Interlingua was developed to combine a simple, mostly regular grammar with a vocabulary common to a wide range of western European languages, making it easy to learn for those whose native languages were sources of Interlingua's vocabulary and grammar.

International 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, Continental English, General English and Common English. These terms may describe the fact that English is spoken and used in numerous dialects around the world or refer to a desired standardisation (i.e. Standard English).

There have been many proposals for making International English more accessible to people from different nationalities but there is no consensus; Basic English is an example, but it failed to make progress. More recently, there have been proposals for English as a lingua franca (ELF) in which non-native speakers take a highly active role in the development of the language.
