Call for verse within novel I revised (7)
I believe the answer is:
involve
'call for' is the definition.
('involve' can be a synonym of 'call for')
'verse within novel i revised' is the wordplay.
'verse' becomes 'v'.
'within' is an insertion indicator.
'revised' indicates anagramming the letters.
'novel'+'i'='noveli'
'noveli' is an anagram of 'inolve'.
'v' going into 'inolve' is 'INVOLVE'.
(Other definitions for involve that I've seen before include "Entangle; complicate" , "Engage as a participant" , "Consist of, or include" , "Concern" , "Implicate or be bound up with" .)
