Constructed languages (conlangs) are those that are artificially constructed, rather than naturally developed.
Constructed languages (conlangs) are languages not developed by natural processes, but instead have an invented grammar, vocabulary, and phonology.
Constructed languages have been developed for a variety of purposes, including:
- Nationality transcendence and political neutrality (Esperanto)
- Use in fiction (Quenya, Klingon)
- The amusement of the inventor
Esperanto is one of the most popular constructed languages, possibly having up to 2 million speakers worldwide. source
