The SIGN LANGUAGE is a full and rich type of language using sign patterns to convey meaning. Furthermore, the expressions of the face and the body posture are part of the grammatical and syntax structure of the sign language.
Most people who do not have personal or social encounters with deaf or hearing impaired people believe that the sign language is a form of pantomime. However, the sign language is not used to create “pictures” or “symbols” when used to refer to a specific object, but rather, signs that correspond to the words, even the phrases of the spoken languages. The pictures are easily understood by everyone, but the words and the signs need to be learned. In other word, one cannot learn the sign language through reading, but through the way it is taught and the relationship that is developed between the student and the specialist. The behavior of the children who learn and use the sign language is identical to the behavior of the children who learn and use the spoken language.
The sign language, like the spoken language, features the same type of organizational structure, the same type of grammar rules and exhibits similar expressive strength. The users (people and adults) use the sign language in order to cover the same communication needs as their hearing counterparts. That is, to express desires, raise questions, give orders, pass on information, to train and communicate with other people.
