Kept out of sight (3)
I believe the answer is:
hid
'kept out of sight' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hid that I've seen before include "Concealed, kept secret" , "Remained out of sight" , "Kept out of sight" , "Stayed out of sight" , "Concealed in orchids" .)
