Secluded corner (4)
I believe the answer is:
nook
'secluded corner' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nook that I've seen before include "Cranny or niche" , "Hidey-hole" , "Corner or small recess" , "Sheltered corner" , "Recess or cranny" .)
