Animated deer no youngster (7)
I believe the answer is:
bambino
'youngster' is the definition.
(bambino is a kind of youngster)
'animated deer no' is the wordplay.
'animated deer' becomes 'bambi' (I've seen this in another clue).
'bambi'+'no'='BAMBINO'
(Other definitions for bambino that I've seen before include "Babe'" , "Italian child or baby" , "youngster" , "Young child (Italian)" , "Baby with an Italian mother?" .)
