ASL Online Dictionary

There's an interactive dictionary links thousands of signs to sentences illustrating how the signs change, or inflect, from sentence to sentence to show different meanings. The ASL Video Dictionary and Inflection Guide was put together by the Rochester Institute of Technology's National Technical Institute for the Deaf. The CD edition is used in many schools and has been updated for the online version. There are 2700 signs and 650 sentences signed by deaf native signers. Special attention is given to the slight inflections of some signs that can give words nuanced meaning. Access runs $40 a year.
