Sign language
A 'sign language' is a way of communicating by using the hands and other parts of the body. Sign languages are an important way for deaf people to communicate. Deaf people often use them instead of spoken languages. Spoken languages use sounds from the mouth and are understood with the ears. Sign languages use hands and are understood with the eyes. People who are blind and deaf can use sign languages too. They feel each others' hands while they are signing. Deaf people can use sign languages more easily than spoken languages.
