After a video Nakia Smith did with her grandfather went viral, Netflix asked her to explain what Black American Sign Language is, how it came about, and how it differs from American Sign Language.
Black American Sign Language is a dialect of American Sign Language. It’s still a language. It was developed by Black deaf people in the 1800s and 1900s during segregation. For reference, the first American school for the deaf was created in 1817, but only started admitting Black students in 1952. So as a result, Black communities had a different means of language socialization and BASL was born.
Smith demonstrates a few BASL signs that differ from ASL signs and you can see more of those differences in the video w/ her grandfather, who is also deaf.
