"American Sign Language (ASL) is a complex visual-spatial language that is used by the Deaf community in the United States and English-speaking parts of Canada. It is a linguistically complete, natural language.
It is the native language of many Deaf men and women" (Karen Nakamura Deaf Library).
"
ASL is the recognized sign language of the deaf community in the United States of America. As is the case with standardized spoken, written, and signed languages worldwide, ASL conforms to linguistic principles (e.g., semantics, syntax, morphology, phonology, and pragmatics). The complex visual-spatial linguistic structure of ASL is distinct from English, a linear, sequential language based on auditory processes." (AMERICAN SIGN LANGUAGE Position Statement National Association of the Deaf)
"American Sign Language (or ASL, Ameslan) is the dominant sign language
of the Deaf community in the United States" (2005, Downs, Sharon. Make A Difference. University of Arkansas at Little Rock.)
