Rise includes unemployment benefit for a youngster (10)
I believe the answer is:
adolescent
'a youngster' is the definition.
(thesaurus)
'rise includes unemployment benefit' is the wordplay.
'rise' becomes 'ascent' ('ascent' can be a synonym of 'rise'**).
'includes' is an insertion indicator.
'unemployment benefit' becomes 'dole' (I've seen this before).
'ascent' placed around 'dole' is 'ADOLESCENT'.
'for' is the link.
(Other definitions for adolescent that I've seen before include "Developing" , "One growing" , "At the stage between childhood and maturity" , "Person in child-adult transition" , "Youngster" .)
