Love on the dole is trouble (9)
I believe the answer is:
adoration
'love' is the definition.
(to adore someone is to love them)
'on the dole is trouble' is the wordplay.
'on' means one lot of letters go next to another.
'the dole' becomes 'ration' (both can mean to allocate).
'is trouble' becomes 'ado' (both can mean bother or commotion).
'ration' put after 'ado' is 'ADORATION'.
(Other definitions for adoration that I've seen before include "praise" , "passionate allegiance" , "Feeling of profound love" , "high regard" , "Deep love and respect" .)
