Here's a breakdown:
* Deaf communities: Sign languages are the primary communication mode for Deaf communities worldwide.
* Around the world: There are hundreds of sign languages used across the globe, with some estimates reaching over 300.
* Regional variations: Just like spoken languages, sign languages can vary significantly from region to region. For example, American Sign Language (ASL) is different from British Sign Language (BSL) and French Sign Language (LSF).
To give you a more specific answer, I'd need to know what you're looking for.
Do you want to know:
* Where a specific sign language is spoken? (e.g., "Where is American Sign Language spoken?")
* The number of sign languages in a specific country or region?
* The origin and history of a specific sign language?
