Stay out of sight (4)
I believe the answer is:
hide
'stay out of sight' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hide that I've seen before include "Conceal with leather" , "Secrete - animal skin" , "(Place of) conceal(ment)" , "Flog" , "go to ground" .)
