ASL’s roots

A language belongs
to its community.

ASL grew from French signing traditions and the signs Deaf students brought from communities such as Martha’s Vineyard, New York, and Philadelphia.

Deaf students, families, and teachers shaped the language. Their communities continue to shape it today. [1]
