Gestural languages are forms of communication that use hand signs, facial expressions, and body movements instead of spoken words. These languages are often used by individuals who are deaf or hard of hearing, allowing them to express thoughts and emotions effectively. One well-known example is American Sign Language (ASL), which has its own grammar and vocabulary distinct from spoken English. In addition to serving the deaf community, gestural languages can also be used in various contexts, such as mime or dance, where movement conveys meaning. They can enhance communication in noisy environments or when verbal communication is not possible, demonstrating the versatility of human expression.
