Street urchin gets game point, poet leaves (5)
I believe the answer is:
gamin
'street urchin' is the definition.
(I know that gamin is a type of street urchin)
'game point poet leaves' is the wordplay.
'leaves' suggests deleting specific letters.
'game'+'point'='gamepoint'
'gamepoint' with 'poet' taken out is 'GAMIN'.
'gets' is the link.
(Other definitions for gamin that I've seen before include "Ragged child" , "Waif" , "stray" , "Street urchin or impudent child" , "Little urchin" .)
