People like learning a foreign language or special languages because they need them for different purposes. Children, adults and old people can learn them when they read, hear or write. What about blind people and deaf people ? They can learn a special language, too. Deaf people or hard of hearing people use a sing language. A sing language generally uses gestures to communicate. The movements of hands , arms or body and facial expresions help to show speakers thoughts and ideas. The history of the sing language began in Spain in the 17th century. A sing language has special hand movements for every letter. These movements are not always the same . These generally differ from one region to another or one countery to another. But it doesn´t make big in problems in communication. When they use this language, communication is possible, even in another language. There is a language for blind people, too. They use a special language. Louis Braille, a Frenchman, invented a system for blind people. He was blind. This system is for reading and writing and there are points like small dots from one to six. Every latter has different dots and people can read these latters when they pass their fingers over the characters. Every language adopted this system. Learning doesn´t have excuses. If you want to learn, you can learn. Go ehead. Good luck!
