ASL stands for American Sign Language. This is the most commonly used sign language among the Deaf community in the United States as well as parts of Canada. Because sign languages are not invented languages, nor are they the signed counterparts of the spoken languages of their region, the grammatical structure of sign languages is clearly distinct from spoken languages. While spoken languages are made up of a combination of sounds (phonemes), sign languages are made of a combination of handshapes, palm orientations, locations, movements, and non-manual markers, such as facial expressions. Students who enroll in our ASL courses online will learn more about the grammatical features of ASL.
