Some vindictive charge (6)
I believe the answer is:
indict
'charge' is the definition.
(I know that indict is a more specific form of the action charge)
'some vindictive' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'INDICT' is hidden in the letters of 'vindictive'.
(Other definitions for indict that I've seen before include "Make accusation or charge against an accused" , "Charge (someone) with a crime (mainly US)" , "Make written statement of charge or accusation" , "Formally charge with a crime" , "Charge (someone) with serious crime" .)
