An artificial language is a language that has been created by humans rather than naturally developed. Esperanto is an example of an artificial language, created in 1887 by L.L. Zamenhof with the intention of providing a universal second language. It is based on European languages and is now spoken by millions of people around the world. CANAL is another artificial language, created in the early 2000s by a group of linguists. It is designed to be easy to learn and is based on English, Spanish, French, and Italian.
