Awning (6)
I believe the answer is:
canopy
'awning' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for canopy that I've seen before include "Ornamental awning" , "Covering against sun or rain" , "Hanging cover forming shelter over bed or throne" , "Uppermost branches of forest trees" , "Roof-like awning" .)
