Performed a ritual that holds back abuse (6)
I believe the answer is:
tirade
'abuse' is the definition.
(verbal abuse)
'performed a ritual that holds back' is the wordplay.
'that holds' indicates a hidden word.
'back' says the letters should be written backwards.
'edarit' can be found hidden inside 'performed a ritual'.
'edarit' reversed gives 'TIRADE'.
(Other definitions for tirade that I've seen before include "Broadside of denunciation" , "Verbal outburst" , "Erode or melt (material)" , "String of invectives" , "strong words" .)
