Denounce celebrity accepting help making a comeback (9)
I believe the answer is:
repudiate
'denounce' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for repudiate that I've seen before include "Give denial" , "Refuse to be associated with" , "Make a disclaimer" , "Denounce" , "Renounce, disown" .)
