2. Sign Language
Sign language is used by deaf people. Since they can't hear, and many of them can't speak, they need the sign language. They use hand, arm, and face signals. It is not just deaf people who learn sign language. People who have a deaf relative, people who work with the deaf people and people who want to support the deaf people also learn sign language. But it is very difficult to learn. Some people think that sign language is similar to general language, but this is not true. Also, some people think that deaf people everywhere in the world use the same sign language, it is not true as well. Sign languages are very different from country to country.
