American Sign Language:  "everywhere"

There isn't "one" perfect and widely established sign for "everywhere."
We have signs for "every" and for "where." Many people do combine those two signs into a compound "everywhere" sign. When you combine two signs into one to form a compound you tend to reduce the movements of the individual signs, so "EVERY" ends up being signed as "EACH" with a single downward movement.
 

I'll paste my sign for "where" from the WHERE page here, but obviously the "WH-type question" facial expression I'm using would not be used as part of the "everywhere" sign.
 

EACH / EVERY	WHERE

 

EVERY (version 1)	EVERY (version 2)	EACH (version 2)

If the context allows it, I prefer to use a two-handed "all over out there" type of sign.
