sign language alphabet

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 The ASL manual alphabet is a system that uses the signer's dominant hand to represent each letter of the English language alphabet. Finger spelling is the act of using a manual alphabet to sign each individual letter of a word. Finger spelling is used for proper nouns, such as names, places, titles, and brands. Sign language is manual communication commonly used by people who are deaf. Sign language is not universal; people who are deaf from different countries speak different sign languages. The gestures or symbols in sign language are organized in a linguistic way. A good example is the difference between American Sign Language (ASL) and British Sign Language (BSL). Both the spoken languages of these communities are the same in that they verbally speak in English, although minute differences exist, for example, the difference between sidewalk and pavement.
