Novel in genuine resumption (7)
I believe the answer is:
renewal
'resumption' is the definition.
(I've seen this before)
'novel in genuine' is the wordplay.
'novel' becomes 'new' (similar in meaning).
'in' indicates putting letters inside.
'genuine' becomes 'real' (associated in meaning).
'new' going into 'real' is 'RENEWAL'.
(Other definitions for renewal that I've seen before include "Revitalisation" , "Fresh beginning" , "Regeneration" , "fresh start" , "Process of extending a subscription or licence" .)
