New York city gangster meeting sticky end after Prohibition (6)
I believe the answer is:
albany
'new york city' is the definition.
(I've seen this in another clue)
'gangster meeting sticky end after prohibition' is the wordplay.
'gangster' becomes 'al' (Al Capone).
'meeting' is a charade indicator (letters next to each other).
'end' indicates one should take the final letters.
'after' is a charade indicator (letters next to each other).
'prohibition' becomes 'ban' (ban is a kind of prohibition).
The final letter of 'sticky' is 'y'.
'y' put after 'ban' is 'bany'.
'al' next to 'bany' is 'ALBANY'.
(Other definitions for albany that I've seen before include "Husband of Goneril (Lear)" , "capital in USA" , "Capital of New Yorki state" , "Capital of NY state" , "and a third" .)
