Tableware ten diners ordered (6,3)
I believe the answer is:
dinner set
'tableware' is the definition.
(dinner set is a kind of tableware)
'ten diners ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'ten'+'diners'='tendiners'
'tendiners' is an anagram of 'DINNER-SET'.
(Other definitions for dinner set that I've seen before include "China" , "might be taken out for a meal" , "Complete service of plates and dishes for a meal" , "Plates etc" , "Collection of plates and dishes" .)
