Affectionate call after a party (7)
I believe the answer is:
adoring
'affectionate' is the definition.
(thesaurus)
'call after a party' is the wordplay.
'call' becomes 'ring' (telephone call).
'after' is a charade indicator (letters next to each other).
'party' becomes 'do' (do is a kind of party).
'a'+'do'='ado'
'ring' put after 'ado' is 'ADORING'.
(Other definitions for adoring that I've seen before include "Passionate" , "Devoted" , "Giving great love" , "Extravagantly indulgent" , "Holding dear" .)
