Staple shape for dishes (6)
I believe the answer is:
plates
'dishes' is the definition.
(plate is a kind of dish)
'staple shape' is the wordplay.
'shape' is an anagram indicator.
'staple' with letters rearranged gives 'PLATES'.
'for' acts as a link.
(Other definitions for plates that I've seen before include "Staple for food containers" , "dentures" , "They're on the table" , "Eating utensils of staple kind" , "Flat dishes" .)
