Condemn show again (7)
I believe the answer is:
reprove
This clue is a double definition.
'condemn' is the first definition.
(thesaurus)
'show again' is the second definition.
('prove' is an answer for 'show' so perhaps 'reprove' is OK for 'show again')
(Other definitions for reprove that I've seen before include "Chide" , "carpet" , "To remonstrate" , "tick off" , "Rebuke, censure" .)
