ASL video dictionary and inflection guide

The ASL Video Dictionary and Inflection Guide shows thousands of 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, ASL 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. The experts at RIT’s National Technical Institute for the Deaf have developed this innovative dictionary that not only shows you 2,700 signs, but shows most of them in sentences. You can see the inflections and learn how they work to help gain a true understanding of the language of ASL, not just a list of its vocabulary.

This powerful program has many interactive features to help learn and study ASL.
