Nonverbal approval (3)

Ross

I believe the answer is:

nod

'nonverbal approval' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for nod that I've seen before include "Doze" , "Asleep in the land" , "Where Cain went to" , "Signify agreement" , "'A . . . is as good as a wink to a blind horse'" .)

I've seen this clue in the Universal and the Newsday.
