British Sign Language interpreting is the means of passing messages between hearing and hard of hearing people, through a variety of ways, which include using different hand shapes and movements, facial expressions, lip patterns, upper body and head movement.
As well as translating the meaning of the words, professional interpreters transfer the real meaning and feeling with its own grammar and syntax.
The British Deaf Association estimates that there are approximately 70,000 people in Britain, whose first or preferred language is BSL.
