Around my house, we use a very simple sign for "DRYER" (a device that dries
clothing) -- we just do a double movement on the sign DRY. Much of the
meaning for this sign is conveyed by context. Most of the time you can
just sign "dry." For example, "Put your clothes in the dryer" = "YOUR
CLOTHES, PUT DRY." It is obvious that you mean "the dryer."
To do the sign for
"dry," change an index finger into an X handshape as your
pull your hand from left to right in front of your mouth. (Left handed
people do the opposite.)
actually touch the mouth.
To be even more clear, you can sign DRYER by doing the sign DRY twice.
Another way to sign DRYER is to combine the sign for dry and "spin around."
I might use this version on the "first usage" in a conversation and then
drop the "spin around."
