Pure and virtuous (6)
I believe the answer is:
chaste
'pure and virtuous' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for chaste that I've seen before include "Pure - virtuous" , "He-cats could be virtuous, strangely" , "Undefiled" , "Maidenly" , "Decorous" .)
