The sign for "sun" has several versions. Use whatever
version your local teacher or Deaf friends use.
Here is version of "sun"
that is based on the sign "sunlight"
(like a ray of sunlight coming down from the sky.) If you just do a
small movement, it is interpreted as "sun." If you do a larger
downward movement it will be interpreted as "sunlight."
Circle a flattened "O" handshape once and then bring it downward
an inch or two as you open it
Sample sentence: "Why do pilots wear sun glasses?"
= PLANE-PERSON USE SUN GLASSES, WHY?
Note: Usually I tend to just
spell S-U-N and sign glasses.
As with most compound signs, the movements are condensed and quick.
There is another popular version of the sign for "sun" that uses a "C"
Start near the eye and move it up into the "sky."
SUN ("C"-hand version)
Note: The "C"-hand version of SUN is somewhat paired with the sign for
"moon." The sign for "sun" uses a full "C" hand, whereas the
sign for "moon" uses just the thumb and index finger.
