Catalogue of exquisite misery (7)
I believe the answer is:
itemise
'catalogue' is the definition.
(both can mean to make a list)
'of exquisite misery' is the wordplay.
'of' says the answer is hidden in the clue.
'ITEMISE' is hidden within 'exquisite misery'.
(Other definitions for itemise that I've seen before include "Formulate a list" , "break down" , "List each thing separately" , "catalogue" , "Enumerate" .)
