Bullfighter some diplomat adores (7)
I believe the answer is:
matador
'bullfighter' is the definition.
(synonyms)
'some diplomat adores' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'MATADOR' can be found hidden inside 'diplomat adores'.
(Other definitions for matador that I've seen before include "He kills the bull in formal fight" , "fighter in the ring?" , "A bull-fighter.11 Beginning to develop" , "Principal bullfighter" , "Ring butcher" .)
