ASSIGNMENT (index finger to palm version)
Yes, I'm cheating on my assignment (heh) and using the same graphic as I use in the sign for "NEGATIVE."
(Bad teacher.) Actually to differentiate between the two signs (if you need to) you can start the sign "ASSIGNMENT" closer to the mouth.
ASSIGNMENT ("appointment" version)This sign circles (horizontally, either counterclockwise or clockwise but I prefer clockwise) the dominant hand in an "A" handshape above the stationary non-dominant "A" hand (or "S" hand) then bring the dominant hand down on top of the non-dominant hand.
