How Pidgin Signed English Bridges ASL and English | verywellhealth
What kind of sign language is it when you do not sign pure American Sign Language (ASL) with its own grammar or use signed exact English? It is called pidgin signed English or PSE. A more recent term is “contact signing,” which conveys that it is a language that develops between people who have contact with English and signing.
One variety is Conceptually Accurate Signed English (CASE) which chooses the sign based on its meaning in ASL rather than its sound or spelling in English but uses English grammatical order in constructing the signing. This differs from Manually Coded English where the signs represent English words rather than the concepts they represent in ASL.
