It is incompatible with spoken English. Hearing people attach English words to signs so they can better understand the unspoken message. But hearing people must understand that signing is not using English, even if they sign in English word order. The importance of signs in the life of a deaf person cannot be underestimated. It is important for deaf children to learn signs.
Signs are the language of the deaf.
Thus, a majority of profoundly deaf adults sign fluently, even those raised orally or with Cued Speech. It is important to note that the Cued Speech group of young adults also lipread with ease and have a natural tendency to swing back and forth between the hearing and the deaf world. The deaf must be able to learn to read and write and be literate members of society. Being deaf does not mean being dumb. Hearing people underestimate the ability of deaf children if they expect no more than a fourth grade reading level from deaf children graduating high school.
