Cost including epic rewritten for Cliff (9)
I believe the answer is:
precipice
'cliff' is the definition.
(precipice is a kind of cliff)
'cost including epic rewritten' is the wordplay.
'cost' becomes 'price' (price is a kind of cost).
'including' indicates putting letters inside.
'rewritten' indicates anagramming the letters.
'epic' with letters rearranged gives 'ecip'.
'price' placed around 'ecip' is 'PRECIPICE'.
'for' acts as a link.
(Other definitions for precipice that I've seen before include "High, very steep cliff" , "Sheer drop" , "Steep cliff face" , "High vertical cliff" , "Overhanging cliff or rock face" .)
