Recommendation of American director with immoral habit (6)
I believe the answer is:
advice
'recommendation' is the definition.
(I've seen this in another clue)
'american director with immoral habit' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'director' becomes 'd' (abbreviation eg in film reviews).
'with' is a charade indicator (letters next to each other).
'immoral habit' becomes 'vice' (I have seen 'Bad habit' mean 'vice' so perhaps 'habit' could also mean 'vice'. I am not sure about the 'immoral' bit.).
'a'+'d'+'vice'='ADVICE'
'of' is the link.
Can you help me to learn more?
(Other definitions for advice that I've seen before include "Supposed words of wisdom" , "Formal notice" , "Intelligence" , "Suggestion for appropriate course of action" , "Supposedly wise words" .)
