Cited true form of morality (9)
I believe the answer is:
rectitude
'morality' is the definition.
(I know that rectitude is a type of righteousness)
'cited true form' is the wordplay.
'form' indicates an anagram (another form of the letters).
'cited'+'true'='citedtrue'
'citedtrue' with letters rearranged gives 'RECTITUDE'.
'of' is the link.
(Other definitions for rectitude that I've seen before include "Correctness" , "Certitude about moral goodness" , "Uprightness, integrity" , "Strict propriety" , "Moral integrity" .)
