Foxy (3)
I believe the answer is:
sly
'foxy?' is the definition.
(I know that foxy can be written as sly)
This is the entire clue.
(Other definitions for sly that I've seen before include "'Crafty, cunning (3)'" , "Cunning, foxy" , "Devious, cunning" , "Doing things in unpleasant and secret way" , "Wily, shifty" .)
