American Sign Language, or ASL as it’s often abbreviated to, is a natural visual language. It originally evolved from French Sign Language and has adopted a wide variety of home signs—signs first used by a small group of deaf people that then become widely adopted—along the way. Written and directed by Professor Geoffrey S. Poor, 1,000 Words to Sign is a practical, authoritative, and effective learning aid to this beautiful and creative language. Numbers, letters of the alphabet, days of the week, colors, and countries of the world are all covered, along with essential words that will allow you to express yourself, understand others, and communicate clearly. When ASL signs and sentences are put together, the result is a playful, creative, and beautiful language of great precision and eloquence.
