Love helping after a party (9)
I believe the answer is:
adoration
'love' is the definition.
(thesaurus)
'helping after a party' is the wordplay.
'helping' becomes 'ration' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'party' becomes 'do' (do is a kind of party).
'a'+'do'='ado'
'ration' put after 'ado' is 'ADORATION'.
(Other definitions for adoration that I've seen before include "passionate allegiance" , "Not a radio (anag.)" , "enormous respect" , "Hero-worship" , "holding someone up a lot" .)
