Attraction for important pickpocket (3,6)
I believe the answer is:
big dipper
'pickpocket' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'attraction for important' is the wordplay.
'attraction' becomes 'dipper' (I can't explain this - if you can you should give a lot more credence to this answer).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'important' becomes 'big' (similar in meaning).
'dipper' put after 'big' is 'BIG DIPPER'.
Can you help me to learn more?
(Other definitions for big dipper that I've seen before include "Familiar US stars" , "Large bird" , "Amusement park attraction" , "rollercoaster" , "North American 24 across" .)
