The Ultimate American Sign Language Dictionary is the first sign language dictionary on CD-ROM to be totally accessible to deaf users. Produced by an award-winning team of professionals in the field of deaf education, over three years of research went into the development of this innovative software. Designed to be a true dictionary for deaf and hearing people alike, this package provides an opportunity to discover how ASL signs and English relate through meaning. The meaning of signs that have no single English word equivalent can be discerned (e.g., What's happening?), and multiple English words that share the same sign (e.g., all, total, whole) can be found by describing the sign. Variations of a single English word that share the same sign (e.g., happy, happily) are shown with the part of speech.
