Sign language is used by deaf and hard-of-hearing people to communicate. Instead of sound, it uses hand motions, facial expressions, and body movements for communication. Different regions of the world have different forms. In America, we use the ASL, the American Sign Language.
American Sign Language (ASL) is commonly used in the US and English-speaking parts of other countries in North America. In regards to the most used languages in the US, you may be surprised to discover American Sign Language ranks fourth. Many universities accept ASL as a foreign language and you can study for a bachelor’s or master’s degree in ASL.
It is estimated between 500,000 and 2 million Americans can communicate using ASL.
As one would expect, the origins are based on necessity. Early use can be found in Martha’s Vineyard way back in the late 17th century. There was a very high rate of deafness amongst the community at Martha’s Vineyard.
