"War and Peace," for one (4)
I believe the answer is:
epic
'war and peace for one' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for epic that I've seen before include "Long poem, book, film" , "eg The Iliad" , "Impressively great" , "Long literary work about great events" , "Long story telling of a hero's deeds" .)
