Desk compartment (6)
I believe the answer is:
drawer
'desk compartment' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for drawer that I've seen before include "Sliding storage box" , "Person writing cheque" , "Sliding part in a piece of furniture" , "neither winner nor loser?" , "Boxlike compartment in piece of furniture" .)
