Dish; coat with metal (5)
I believe the answer is:
plate
I believe this is a double definition.
'dish' is the first definition.
(I know that dish can be written as Plate)
'coat with metal' is the second definition.
(I've seen this before)
(Other definitions for plate that I've seen before include "horseshoe" , "trophy" , "impression" , "Helping of food" , "Cover with metal" .)
