Here's a breakdown of its key functions:
* Primary Language: For many deaf individuals, sign language is their first and primary language. It's how they learn, think, and express themselves.
* Visual Communication: Unlike spoken language, sign language is visual, utilizing handshapes, facial expressions, and body movements to convey meaning.
* Cultural Identity: Sign language is more than just a means of communication; it's a vital part of deaf culture. It fosters a sense of community and shared identity.
* Accessibility: Sign language provides access to information and education for deaf people. It allows them to participate fully in society, learn, work, and connect with others.
* Preservation of Culture: Each sign language is unique, reflecting the history and culture of its users. By learning and using sign language, we contribute to its preservation.
It's important to note that sign language is not a universal language. Different countries and regions have their own unique sign languages, just like spoken languages.
