To put a wrong clause right is only civil (7)
I believe the answer is:
secular
'civil' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for secular that I've seen before include "Not concerned with religion" , "Non-religious" , "Profane" , "Not spiritual" , "without religion" .)
