Morals of ladies becoming corrupted (6)
I believe the answer is:
ideals
'morals' is the definition.
(I've seen this before)
'ladies becoming corrupted' is the wordplay.
'becoming corrupted' is an anagram indicator.
'ladies' anagrammed gives 'IDEALS'.
'of' acts as a link.
(Other definitions for ideals that I've seen before include "High standards for ladies" , "Lofty aims for ladies" , "Noble aspirations for ladies" , "Standards for attainment or imitation" , "Moral standards" .)
