Sign Language
Sign Language you would think is only for deaf people. Guess again. Everybody uses sign language. Sign Language is a pose or motion made by your body. There are millions of people in America with hearing disabilities. Many deaf people in the USA use American Sign Language or ASL for short. Sign Language isn't always used for just the alphabet. It can be used to express money, pizza, or emotions.
