Right - not, vice versa, wrong (12)
I believe the answer is:
conservative
'right' is the definition.
(associated in meaning)
'not vice versa wrong' is the wordplay.
'wrong' is an anagram indicator.
'not'+'vice'+'versa'='notviceversa'
'notviceversa' with letters rearranged gives 'CONSERVATIVE'.
(Other definitions for conservative that I've seen before include "(Of dress) conventional and sober" , "Traditionalist" , "politician" , "True blue" , "square" .)
