Aide's fist destroyed content (9)
I believe the answer is:
satisfied
'content' is the definition.
('satisfied' can be similar in meaning to 'content')
'aide's fist destroyed' is the wordplay.
'destroyed' indicates anagramming the letters.
'aides'+'fist'='aidesfist'
'aidesfist' with letters rearranged gives 'SATISFIED'.
(Other definitions for satisfied that I've seen before include "Complied with (a condition)" , "Well catered for" , "relieved of doubt" , "as one may be with a second helping" , "Pleased, contented" .)
