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.
Separation of mechanism and policyThe separation of mechanism and policy is a design principle in computer science. It states that mechanisms (those parts of a system implementation that control the authorization of operations and the allocation of resources) should not dictate (or overly restrict) the policies according to which decisions are made about which operations to authorize, and which resources to allocate. While most commonly discussed in the context of security mechanisms (authentication and authorization), separation of mechanism and policy is applicable to a range of resource allocation problems (e.
Philosophical languageA philosophical language is any constructed language that is constructed from first principles. 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 (i.e. scientific) 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.
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.
