Street urchin: a male consumed by alcohol (5)
I believe the answer is:
gamin
'street urchin' is the definition.
(gamin is a kind of street urchin)
'a male consumed by alcohol' is the wordplay.
'a male' becomes 'am' (I've seen this in other clues).
'consumed by' is an insertion indicator.
'alcohol' becomes 'gin' (gin is a kind of alcohol).
'am' put into 'gin' is 'GAMIN'.
(Other definitions for gamin that I've seen before include "Waif" , "Little urchin" , "Ragged child" , "Street urchin or impudent child" , "Little devil" .)
