Sign language is a visual means of communication that uses hand shapes, facial expressions, and body movements to convey meaning. It is primarily used by the deaf and hard of hearing communities, allowing them to communicate effectively without spoken words. Each country often has its own unique sign language, such as American Sign Language (ASL) or British Sign Language (BSL). Sign language is not universal; different regions have developed distinct systems. It includes grammar and syntax, making it a fully functional language. Learning sign language can foster better communication and understanding between hearing individuals and those who are deaf or hard of hearing.
