Piece of dinnerware (5)
I believe the answer is:
plate
'piece of dinnerware' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for plate that I've seen before include "Illustration on special paper in a book" , "that batter will stand on" , "Put film on" , "Coat with metal" , "Flat dish; gold and silver ware" .)
