Hint for one's confidant (8)
I believe the answer is:
I believe this clue is a double definition.
'hint' is the first definition.
(I know that intimate is a more specific form of the action hint)
'one's confidant' is the second definition.
(intimate can mean a friend of confidant)
'for' is the link.
(Other definitions for intimate that I've seen before include "Bosom" , "Tip off" , "Personal - hint - friend" , "Suggest to trusted friend?" , "cosy" .)
