Personal hint (8)
I believe the answer is:
intimate
I believe this clue is a double definition.
'personal' is the first definition.
('intimate' can be a synonym of 'personal')
'hint' is the second definition.
(intimating is a kind of hinting)
(Other definitions for intimate that I've seen before include "Private and personal like close acquaintanceship" , "Personal - hint - friend" , "Close acquaintance" , "Infer; personal" , "Familiar; imply" .)
