Reviled old rogue? (8)
I believe the answer is:
evildoer
'reviled old rogue?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'reviled old rogue?' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'rogue?' indicates anagramming the letters (I've seen 'rogue' mean this).
'reviled'+'o'='reviledo'
'reviledo' with letters rearranged gives 'EVILDOER'.
(Other definitions for evildoer that I've seen before include "Rode live over morally bad person" , "Over idle (anag) - villain" , "miscreant" , "criminal!" , "One committing wicked deeds" .)
