Corrupt woman, quiet one, seen with saint (9)
I believe the answer is:
dishonest
'corrupt' is the definition.
(associated in meaning)
'woman quiet one seen with saint' is the wordplay.
'woman' becomes 'Di' (short for Diana).
'quiet' becomes 'sh' (both can be said to tell someone to be quiet).
'seen with' is a charade indicator (letters next to each other).
'saint' becomes 'st' (abbreviation).
'di'+'sh'+'one'+'st'='DISHONEST'
(Other definitions for dishonest that I've seen before include "Not true!" , "shady" , "shifty" , "cheat" , "Corrupt" .)
