Lives with a girl in spring (5)
I believe the answer is:
issue
'spring' is the definition.
(thesaurus)
'lives with a girl' is the wordplay.
'lives' becomes 'is' ('be' can be a synonym of 'live').
'with' is a charade indicator (letters next to each other).
'a girl' becomes 'sue' (girl's name).
'is'+'sue'='ISSUE'
'in' acts as a link.
(Other definitions for issue that I've seen before include "Problem < children" , "Spring - children - publication" , "Important question" , "Number (of periodical)" , "that may be taken where there's disagreement?" .)
