American Sign Language is a well known natural language that is predominant among deaf communities in the United States of America and Canada. ASL based creoles and ASL dialects are also used in many different parts of the globe such as in certain countries of Southeast Asia and West Africa. ASL is often learned by people around the world as a second language and has close resemblance to French. ASL as a language originated in the famous school for deaf children in America that was established in the early part of the 19th century. Since then, ASL came to be used quit widely in schools meant for deaf people all over America.
The ASL signs are comprised of Phonemic components that include the movement of the torso and the face as well as the hands. While ASL cannot be regarded as a form of pantomime, it is necessary to note that iconicity plays a far more crucial role in ASL than it does in any spoken language. ASL grammar is not related to English grammar. ASL has aspectual marking and verbal agreement with a very productive system of agglutinative classifier formation. Certain linguists regard ASL as an SVO or subject-verb-object language though there are many alternative proposals that can account for the ASL word order.
Pigdin Signed English is as sign language that entails a combination of English and the American Sign Language or ASL. ASL is known to be quite distinct as a language and cannot be regarded as similar to English in any way. The ASL syntax is very different and there are no equivalents in English for specific words that are used as a part of the ASL language. People who are culturally deaf and who sign with each other make use of ASL but there are many people who are hard of hearing or frequently deaf learning sign language later in their lives, after having learnt English first that is, who do not sign in ASL strictly but rather using a mixture of English and ASL that is known as Pigdin Signed English or PSE.
When communicating in PSE, a person may sign using approximately an English syntax and sign mostly the English words in a sentence. PSE is not the same as Signed Exact English or SEE that makes use of exact English sign language words and signs that do not even exist in the ASL and the exact English order of words. PSE is mainly used by people who speak English as the primary language. Culturally deaf people tend to be quite adept at understanding as well as using PSE when signing with a person who does not use ASL strictly.
Signed Exact English is a form of manual communication which strives to represent with full exactness the English grammar and vocabulary. It is widely used in a number of English speaking countries and is related in a significant way to SEE-1 or Seeing English Language that was invented in the year 1971 and which is based on English word morphemes. Signed Exact English uses a lot of the vocabulary that is contained in American Sign Language or ASL. It however modifies the hand shapes which are used in ASL for the purpose of using the hand shape of the very first letter of a corresponding English word. When it comes to Signed Exact English the four components of the signs include movement, location, orientation and hand shape.
A huge reason for the popularity of the Signed Exact English language is the fact that it is quite easy to pick up. It has promoted reading skills in deaf children by a considerable degree and has actually helped deaf children to graduate from school and even attend college. Signed Exact English is easy to use and master for non verbal and non deaf individuals who have highly receptive skills in the English language, such as autistic children for example.
