Still in dodgy ethics (3)
I believe the answer is:
yet
'still' is the definition.
(yet can mean still or so far)
'in dodgy ethics' is the wordplay.
'in' indicates a hidden word.
'YET' is hidden in the letters of 'dodgy ethics'.
(Other definitions for yet that I've seen before include "Though; still" , "Up to this time and continuing" , "Still; nevertheless" , "Still, so far" , "in spite of that" .)
