Urbane, put money aside to cover university (5)
I believe the answer is:
suave
'urbane' is the definition.
(thesaurus)
'put money aside to cover university' is the wordplay.
'put money aside' becomes 'save' (I've seen this before).
'to cover' indicates putting letters inside.
'university' becomes 'u'.
'save' placed around 'u' is 'SUAVE'.
(Other definitions for suave that I've seen before include "Debonair" , "Charming, elegant" , "Charming, confident" , "Superficially polite" , "Smooth-mannered and sophisticated" .)
