Trouble with allowance, love? (9)
I believe the answer is:
adoration
'love?' is the definition.
(thesaurus)
'trouble with allowance' is the wordplay.
'trouble' becomes 'ado' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'allowance' becomes 'ration' (I've seen this before).
'ado'+'ration'='ADORATION'
(Other definitions for adoration that I've seen before include "Not a radio (anag.)" , "enormous respect" , "Deep love and respect" , "passionate allegiance" , "Hero-worship" .)
