It's important to note that there are many different sign languages around the world, just like there are many spoken languages. These sign languages are not simply visual representations of spoken languages; they have their own unique grammatical structures, syntax, and vocabulary.
Here's a breakdown of why sign language is considered visual-gestural:
* Visual: Sign language relies on seeing the signs, rather than hearing sounds.
* Gestural: The signs themselves are primarily made with the hands, but also involve facial expressions and body movements.
Here are some further points about sign languages:
* Not universal: While there are some similarities between sign languages, they are not universally understood. Different countries and regions have their own distinct sign languages.
* Full-fledged languages: Sign languages are complete and complex languages, with their own grammar, syntax, and vocabulary. They are not just a collection of gestures.
* Diverse and evolving: Sign languages are constantly evolving and changing, just like spoken languages.
