As we all know sign language a way of communicating among people who are having hearing disabilities. It comprises of hand gestures, face expressions, body language and lip patterns. Their spatial grammar are different from normal grammar of spoken languages. Hundreds of sign languages are used around the world and are at the cores of the local Deaf Cultures. Some sign languages have obtained some form of legal recognition, while others have no status at all. In addition to sign languages, various signed codes of spoken languages have been developed, such as signed English and Walpiri Sign Languages. These are not to be confused with languages, oral or signed; a signed code of an oral language is simply a signed mode of the language it carries, just as a writing system is a written mode. Signed codes of oral languages can be useful for learning oral languages or for expressing and discussing literal quotations from those languages, but they are generally too awkward and unwieldy for normal discourse. For example, a teacher and deaf student of English in the United States might use Signed English to cite examples of English usage, but the discussion of those examples would be in American Sign Language.
Uses Of Signs In Hearing Communities
Sign language can be used in various different types of situations, where speech is not permitted or practical for example, in cloistered religious communities, scuba diving, television recording studios and stock exchanges. Sometimes, if the prevalence of deaf people is high enough, a deaf sign language will be taken up by an entire local community.
