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.
LojbanLojban (pronounced ˈloʒban) is a logical, constructed, human language created by the Logical Language Group which aims to be syntactically unambiguous. It succeeds the Loglan project. The Logical Language Group (LLG) began developing Lojban in 1987. The LLG sought to realize Loglan's purposes and further improve the language by making it more usable and freely available (as indicated by its official full English title, Lojban: A Realization of Loglan).
Linguistic relativityThe idea of linguistic relativity, also known as the Sapir–Whorf hypothesis səˌpɪərnbspˈhwɔːrf , the Whorf hypothesis, or Whorfianism, is a principle suggesting that the structure of a language influences its speakers' worldview or cognition, and thus individuals' languages determine or shape their perceptions of the world. The hypothesis has long been controversial, and many different, often contradictory variations have existed throughout its history.
LinguisticsLinguistics is the scientific study of language. The modern-day scientific study of linguistics takes all aspects of language into account — i.e., the cognitive, the social, the cultural, the psychological, the environmental, the biological, the literary, the grammatical, the paleographical, and the structural. Linguistics is based on a theoretical as well as descriptive study of language, and is also interlinked with the applied fields of language studies and language learning, which entails the study of specific languages.
