sign language alphabet
There are over 300 different sign languages that vary from nation to nation. In addition to BSL, there are several sign languages used by English-speaking countries, including ASL, Auslan (in Australia) and NZSL (in new Zealand).Finger spelling is the representation of the letters of a writing system, and sometimes numeral systems, using only the hands. These manual alphabets have often been used in deaf education and have subsequently been adopted as a distinct part of a number of sign languages. An ASL user would use the American Finger spelled Alphabet, (also called the American Manual Alphabet). There are many different manual alphabets throughout the world.
