摘要

More than 140 sign languages are used today, primarily by deaf communities around the world. Like spoken languages, each sign language has its own grammar, vocabulary?and other special features. For example, American Sign Language and British Sign Language are mutually unintelligible. In fact, American Sign Language has more in common with French Sign Language, largely because French educators were instrumental in helping get deaf schools established in the United States during the 19th century.
