The more than 3 500 illustrations arrayed in this volume display the most useful selection of signs to be found in any single ASL reference resource. Each sign illustration, some with fingerspelling depictions, incorporate a complete list of English synonyms. The dictionary also describes the history of ASL, explains the workings of ASL syntax and structure, and includes examples of idions with a special section on ASL classifiers.

A searchable, full-color disc is included, featuring a diverse group of native ASL signers demonstrating the signs. Created by an unparalleled board of experts led by renowned ASL linguist and poet Clayton Valli, the features in this dictionary combine to make it the outstanding ASL reference for instructors, students and users of ASL.
