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.
Global language systemThe global language system is the "ingenious pattern of connections between language groups". Dutch sociologist Abram de Swaan developed this theory in 2001 in his book Words of the World: The Global Language System and according to him, "the multilingual connections between language groups do not occur haphazardly, but, on the contrary, they constitute a surprisingly strong and efficient network that ties together – directly or indirectly – the six billion inhabitants of the earth.
International scientific vocabularyInternational scientific vocabulary (ISV) comprises scientific and specialized words whose language of origin may or may not be certain, but which are in current use in several modern languages (that is, translingually, whether in naturalized, loanword, or calque forms). The name "international scientific vocabulary" was first used by Philip Gove in Webster's Third New International Dictionary (1961). As noted by David Crystal, science is an especially productive field for new coinages.
Characteristica universalisThe Latin term characteristica universalis, commonly interpreted as universal characteristic, or universal character in English, is a universal and formal language imagined by Gottfried Leibniz able to express mathematical, scientific, and metaphysical concepts. Leibniz thus hoped to create a language usable within the framework of a universal logical calculation or calculus ratiocinator. The characteristica universalis is a recurring concept in the writings of Leibniz.
Controlled natural languageControlled natural languages (CNLs) are subsets of natural languages that are obtained by restricting the grammar and vocabulary in order to reduce or eliminate ambiguity and complexity. Traditionally, controlled languages fall into two major types: those that improve readability for human readers (e.g. non-native speakers), and those that enable reliable automatic semantic analysis of the language.
Engineered languageEngineered languages (often abbreviated to engelangs, or, less commonly, engilangs) are constructed languages devised to test or prove some hypotheses about how languages work or might work. There are at least three subcategories, philosophical languages (or ideal languages), logical languages (sometimes abbreviated as loglangs), and experimental languages. Raymond Brown describes engineered languages as "languages that are designed to specified objective criteria, and modeled to meet those criteria".
InterslavicInterslavic (Medžuslovjansky / Меджусловјанскы) is a pan-Slavic auxiliary language. Its purpose is to facilitate communication between speakers of various Slavic languages, as well as to allow people who do not speak a Slavic language to communicate with Slavic speakers by being mutually intelligible with most, if not all, Slavic languages. For Slavs and non-Slavs, it can fulfill an educational role as well. Interslavic can be classified as a semi-constructed language.
An Essay Towards a Real Character, and a Philosophical LanguageAn Essay Towards a Real Character, and a Philosophical Language (London, 1668) is the best-remembered of the numerous works of John Wilkins, in which he expounds a new universal language, meant primarily to facilitate international communication among scholars, but envisioned for use by diplomats, travelers, and merchants as well. Unlike many universal language schemes of the period, it was meant merely as an auxiliary to—not a replacement of—existing natural 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.
Artistic languageAn artistic language, or artlang, is a constructed language designed for aesthetic and phonetic pleasure. Language can be artistic to the extent that artists use it as a source of creativity in art, poetry, calligraphy or as a metaphor to address themes such as cultural diversity and the vulnerability of the individual in a globalizing world. Unlike engineered languages or auxiliary languages, artistic languages often have irregular grammar systems, much like natural languages.
