Gets gran to change hood (8)
I believe the answer is:
gangster
'hood' is the definition.
(I've seen this in another clue)
'gets gran to change' is the wordplay.
'to change' is an anagram indicator.
'gets'+'gran'='getsgran'
'getsgran' anagrammed gives 'GANGSTER'.
(Other definitions for gangster that I've seen before include "One of the mob, like Al Capone" , "Mafia man" , "Hood, desperado" , "Hoodlum" , "One of a group of violent criminals" .)
