These handshape primes found in ASL (American Sign Language) are the smallest units of language (ASL). This set of handshape primes is called "handshape paramater".
A single ASL word/sign is made up of these five parameters: handshape, movement, location, palm orientation, and non-manual marker. Each parameter has a number of primes. E.g. there are over 45 handshape primes.
The system of the sign language handshape chart below was developed by Jolanta Lapiak in 2013 or earlier. The system is organized into categories from "O" to "10" and 20. The "20" handshapes was originally categorized under "0" till 2015. Each handshape prime has a few examples of the ASL signs that contain the handshape.
