American Sign Language [SEP] Classification
ASL emerged as a language in the American School for the Deaf (ASD), founded in 1817, which brought together Old French Sign Language, various village sign languages, and home sign systems; ASL was created in that situation by language contact. ASL was influenced by its forerunners but distinct from all of them. The influence of French Sign Language (LSF) on ASL is readily apparent; for example, it has been found that about 58% of signs in modern ASL are cognate to Old French Sign Language signs. However, that is far less than the standard 80% measure used to determine whether related languages are actually dialects.
