Gangster; covering (4)
I believe the answer is:
hood
I believe this is a double definition.
'gangster' is the first definition.
(I've seen this in another clue)
'covering' is the second definition.
(I know that hood is a type of covering)
(Other definitions for hood that I've seen before include "Bronx district" , "See 8" , "Outlaw and gangster" , "this could provide cover" , "Head covering or American car bonnet" .)
