Learn SignWriting for American Sign Language/Handshapes

Basic Handshapes
In ASL, there are about 150 distinct handshapes. In SignWriting, the handshape symbols are all derived from 3 basic handshapes:
 * /Closed fist/
 * The S and index finger handshapes are both derived from the closed fist, since the fingers touch the palm in both cases.
 * /Open fist/
 * The O and D handshapes are derived from the open fist, since the fingers contact each other, not the palm.
 * /Flat palm/
 * The claw or 5-hand handshapes are derived from the flat palm, since the fingers do not contact each other or the palm.

Orientation

 * The palm of the hand is represented in white; the back of the hand in black.
 * Signs in the wall plane have no space at the knuckle joint; signs in the floor plane have a small space present.

Combined, these provide easy identifiers for the hand's position in space.
