Arousing feeling I have backing revolutionary book (7)
I believe the answer is:
emotive
'arousing feeling' is the definition.
(I've seen this before)
'i have backing revolutionary book' is the wordplay.
'i have' becomes 'ive'.
'backing' says to put letters next to each other.
'revolutionary' shows that the letters should be reversed in order.
'book' becomes 'tome' (tome is a kind of book).
'tome' in reverse letter order is 'emot'.
'ive' after 'emot' is 'EMOTIVE'.
(Other definitions for emotive that I've seen before include "Stimulating to feelings" , "Moving - controversial" , "Highly-charged" , "Showing feelings" , "Arousing great feeling" .)
