Wildly romanced, clutching English or Italian love stories (9)
I believe the answer is:
decameron
'italian love stories' is the definition.
(collection of tales by Giovanni Boccaccio)
'wildly romanced clutching english' is the wordplay.
'wildly' is an anagram indicator.
'clutching' is an insertion indicator.
'english' becomes 'E' (abbreviation).
'romanced' with letters rearranged gives 'dcameron'.
'dcameron' placed around 'e' is 'DECAMERON'.
'or' is the link.
(Other definitions for decameron that I've seen before include "books" , "Collection of 100 short stories by Boccaccio - rename cod (anag)" , "One hundred stories" , "A hundred tales" , "14th century Italian book of tales" .)
