language specially made for a purpose; non-natural language
An artificial language is a language specially made for a purpose. These languages can be based on an existing natural language or can be artificial.
Some types of artificial languages are:
- Constructed languages take the place of natural languages. They make human communication simpler, or make fictional worlds believable. Basic English, Esperanto, Tolkien's Quenya, and Lojban are examples.
- Formal languages are tools in mathematical logic and computer science where the terms are very precise and clearly defined.
- Computer languages are formal languages used by humans to program computers or for communication among computers. Programming languages and markup languages are types of computer languages.
