* No Central Registry: There's no official body that tracks every artificial language created.
* Varying Definitions: What constitutes an "artificial language" can be debated. Some might include constructed languages like Esperanto, while others might also include programming languages, specialized scientific notations, or even fictional languages from books or movies.
* Constant Creation: New artificial languages are constantly being invented, so any number would be outdated quickly.
However, we can say:
* Thousands Exist: There are definitely thousands of documented artificial languages.
* Esperanto is the Most Widely Known: Esperanto, created in the late 19th century, is the most famous and arguably the most widely spoken constructed language.
* Many are Specialized: Many artificial languages are created for specific purposes, like scientific communication or computer programming.
