Language creation, also known as conlanging, is the process of inventing a new language. This can involve developing unique grammar, vocabulary, and pronunciation rules. Many creators design languages for artistic purposes, such as in literature or film, with notable examples including J.R.R. Tolkien's Elvish languages and Marc Okrand's Klingon for the Star Trek franchise. Some individuals create languages for personal use or as a form of linguistic experimentation. These constructed languages can serve various functions, from facilitating communication among specific groups to exploring linguistic theories. The study of language creation also contributes to our understanding of how languages evolve and interact.
