The sign for "fingerspell" (or "fingerspelling" or
"spell") wiggles the fingers as you move the
hand a bit to the side.
SPELL: Version 2
There is another way to sign fingerspell which looks like you are throwing a
piece of paper. It uses a quick double movement. I use this sign for
sentences like: "I spelled to them." "He spelled to me."
This sign is "directional," it involves "noun/verb" agreement. That means
if you do it like in the picture it means SPELL in general or "I SPELLED it to
YOU." This version is "directional." That means you can modify the sign by
aiming it at a third person or even at yourself. If I aim it at myself
it could mean the person I am talking about spelled something to me.
Note: if you use just a single movement with this variation it can mean a
version of the sign "SEND."
