Rebel Frenchman for example brought back without notice (8)
I believe the answer is:
Here is my best explanation:
'rebel' is the definition.
('renegade' can be a synonym of 'rebel')
'frenchman for example brought back without notice' is the subsidiary indication.
'frenchman' becomes 'rene' (**).
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'brought back' shows that the letters should be reversed in order.
'without' indicates putting letters inside.
'notice' becomes 'ad'.
'eg' reversed gives 'ge'.
'ge' enclosing 'ad' is 'gade'.
(Other definitions for renegade that I've seen before include "Person who deserts from cause or faith", "Treacherous person", "Deserter, betrayer", "Dare Gene to become a rebel", "Outlaw", "Rebel, outlaw", "Rebel deserter", "Deserter, turncoat", "One who deserts cause or faith" and "Apostate".)
