* No Single Origin: Sign languages developed naturally within deaf communities as a way to communicate. It's not a single language that was invented at a specific time.
* Ancient History: Evidence of sign language use dates back centuries, with some scholars believing it existed even in ancient times.
* Diverse Forms: There are hundreds of sign languages around the world, each with its own unique structure and history.
Instead of a specific "start" date, we can look at key moments:
* Formalization and Education: Some sign languages began to be formalized and taught in schools during the 18th and 19th centuries, which helped to standardize them and make them more accessible.
* Modern Recognition: The 20th and 21st centuries saw increased recognition and acceptance of sign languages as valid languages, leading to more research and development.
While we may never know the exact origins of sign language, it's important to recognize its long history and its vital role in the lives of deaf communities around the world.
