The following list of notable constructed languages is divided into auxiliary, ritual, engineered, and artistic (including fictional) languages, and their respective subgenres. All entries on this list have further information on separate Wikipedia articles.
International auxiliary languages (IAL) are languages constructed to provide easy, fast, and/or improved communication among all human beings, or a significant portion, without necessarily replacing native languages.

Zonal auxiliary languages are languages created with the purpose of facilitating communication between speakers of a certain group of related languages. Unlike international auxiliary languages for global uses, they are intended to serve a limited linguistic or geographic area. Examples include Pan-Slavic languages, Pan-Romance languages and Pan-Germanic languages.

Fictional languages are the subset of constructed languages (conlangs) that have been created as part of a fictional setting. 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.
In 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. It can take different forms, typically 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.
An international auxiliary language is a language meant for communication between people from all different nations, who do not share a common first language. An auxiliary language is primarily a foreign language and often a constructed language. The concept is related to but separate from the idea of a lingua franca that people must use to communicate. The study of international auxiliary languages is interlinguistics.
An artistic language, or artlang, is a constructed language designed for aesthetic and phonetic pleasure. Constructed languages 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. They can also be used to test linguistical theories, such as Linguistic relativity.
Engineered languages 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, logical languages, and experimental languages. Raymond Brown describes engineered languages as "languages that are designed to specified objective criteria, and modeled to meet those criteria".
Although not used in general linguistic theory, the term preverb is used in Caucasian, Caddoan, Athabaskan, and Algonquian linguistics to describe certain elements prefixed to verbs. In the context of Indo-European languages, the term is usually used for separable verb prefixes.
Interlinguistics, also known as cosmoglottics, is the science of planned languages that has existed for more than a century. Formalised by Otto Jespersen in 1931 as the science of interlanguages, in more recent times, the field has been more focused with language planning, the collection of strategies to deliberately influence the structure and function of a living language. In this framework, interlanguages become a subset of planned languages, i.e. extreme cases of language planning.
A philosophical language is any constructed language that is constructed from first principles, sometimes following a classification. It is considered a type of engineered language. Philosophical languages were popular in Early Modern times, partly motivated by the goal of revising normal language for philosophical purposes. The term ideal language is sometimes used near-synonymously, though more modern philosophical languages such as Toki Pona are less likely to involve such an exalted claim of perfection. The axioms and grammars of the languages together differ from commonly spoken languages.
The Baháʼí Faith teaches that the world should adopt an international auxiliary language, which people would use in addition to their mother tongue. The aim of this teaching is to improve communication and foster unity among peoples and nations. The Baháʼí teachings state, however, that the international auxiliary language should not suppress existing natural languages, and that the concept of unity in diversity must be applied to preserve cultural distinctions. The Baha'i principle of an International Auxiliary Language (IAL) represents a paradigm for establishing peaceful and reciprocal relations between the world's primary speech communities – while shielding them from undue linguistic pressures from the dominant speech community/communities.
A modern language is any human language that is currently in use as a native language. The term is used in language education to distinguish between languages which are used for day-to-day communication and dead classical languages such as Latin and Classical Chinese, which are studied for their cultural and linguistic value. SIL Ethnologue defines a living language as "one that has at least one speaker for whom it is their first language".
In linguistic typology, object–verb–subject (OVS) or object–verb–agent (OVA) is a rare permutation of word order. OVS denotes the sequence object–verb–subject in unmarked expressions: Oranges ate Sam, Thorns have roses. The passive voice in English may appear to be in the OVS order, but that is not an accurate description. In an active voice sentence like Sam ate the oranges, the grammatical subject, Sam, is the agent and is acting on the patient, the oranges, which are the object of the verb, ate. In the passive voice, The oranges were eaten by Sam, the order is reversed and so that patient is followed by the verb and then the agent. However, the oranges become the subject of the verb, were eaten, which is modified by the prepositional phrase, by Sam, which expresses the agent, and so the usual subject–verb–(object) order is maintained.
Toki Pona is a philosophical, artistic, constructed language designed for its small vocabulary, simplicity, and ease of acquisition. It was created by Canadian linguist Sonja Lang to simplify her thoughts and communication. The first drafts were published online in 2001, while the complete form was published in the 2014 book Toki Pona: The Language of Good. Lang also released a supplementary dictionary, the Toki Pona Dictionary, in July 2021, describing the language as used by its community of speakers. In 2024, a third book was released, a Toki Pona adaptation of The Wonderful Wizard of Oz, written in Sitelen Pona.
A constructed language is a language whose phonology, grammar, orthography, 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 a fictional language. Planned languages are languages that have been purposefully designed; they are the result of deliberate, controlling intervention and are thus of a form of language planning.
Verdurian is a constructed language created by Mark Rosenfelder, first published in 1995 and hosted at his website, Zompist.com.
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 somewhat derogatory term for languages intended for global use but based (almost) exclusively 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.
Arika Okrent is an American linguist and writer of popular works on linguistic topics.
Bible translations into constructed languages include:
In the Land of Invented Languages: Esperanto Rock Stars, Klingon Poets, Loglan Lovers, and the Mad Dreamers who Tried to Build a Perfect Language is a 2009 non-fiction book by linguist Arika Okrent about the history and culture of constructed languages, or conlangs, languages created by individuals. Okrent explores the motivations for creating a language, the challenges faced by such projects, and the outcomes of a number of high-profile conlangs. The book revolves around six conlangs: John Wilkins' unnamed 'philosophical language', Esperanto, Blissymbols, Loglan and its descendant Lojban, and the Klingon language designed for the Star Trek universe. Okrent describes her personal experiences learning and interacting with these languages and their speakers, and provides historical and linguistic analyses of their structures and features.
Sitelen Pona is a constructed logography used for Toki Pona. It was originally designed circa 2013 and published in 2014 by Canadian linguist Sonja Lang, the language's creator.
