Cheese -- a part brought into court (9)
I believe the answer is:
camembert
'cheese' is the definition.
(Camembert is an example)
'a part brought into court' is the wordplay.
'part' becomes 'member' (member is a kind of part**).
'brought into' indicates putting letters inside.
'court' becomes 'ct'.
'a'+'member'='amember'
'amember' inserted inside 'ct' is 'CAMEMBERT'.
(Other definitions for camembert that I've seen before include "For something to eat" , "Soft rich cheese as made in Normandy" , "soft fare" , "Soft creamy French cheese" , "French produce" .)
