Exaggerate about a court (7)
I believe the answer is:
overact
'exaggerate' is the definition.
(thesaurus)
'about a court' is the wordplay.
'about' becomes 'over' (I've seen this before).
'court' becomes 'ct'.
'over'+'a'+'ct'='OVERACT'
(Other definitions for overact that I've seen before include "Cartoon twenty four across" , "Be excessive like fulsome thespian" , "Play role exaggeratedly" , "Perform hammily" , "Perform in an exaggerated manner" .)
