Tray (6)
I believe the answer is:
salver
'tray' is the definition.
(I know that salver is a type of tray)
This is all the clue.
(Other definitions for salver that I've seen before include "Maybe something on which to serve food" , "plate" , "piece of silver" , "A fancy metal tray" , "Tray, could be silver" .)
