Censure each retro top (7)
I believe the answer is:
reproof
'censure' is the definition.
(I've seen this before)
'each retro top' is the wordplay.
'each' becomes 'per' ('per' can mean for each).
'retro' shows that the letters should be reversed in order (retro is Latin for 'backwards').
'top' becomes 'roof' (top of a house).
'per' reversed gives 'rep'.
'rep'+'roof'='REPROOF'
(Other definitions for reproof that I've seen before include "Criticism" , "Reprimand" , "Rocket" , "Dressing down" , "Castigation" .)
