SASL Video Dictionary

What is the SASL Dictionary?

The SASL Video Dictionary shows signs in crisp color video and links them to sentences that demonstrate how they change to convey different meanings. This is critical because unlike English words, SASL signs change - inflect - from sentence to sentence to show different meanings. The sign for help, for example, can change to mean help me, help them, help for a long time, etc.
