Outlaw speed off on rough road? (9)
I believe the answer is:
desperado
'outlaw' is the definition.
(I know that desperado is a type of outlaw)
'speed off on rough road?' is the wordplay.
'off' is an anagram indicator.
'on' is a charade indicator (letters next to each other).
'rough' indicates an anagram (a rough or broken ordering of the letters).
'speed' anagrammed gives 'despe'.
'road' anagrammed gives 'rado'.
'despe'+'rado'='DESPERADO'
(Other definitions for desperado that I've seen before include "reckless type" , "Reckless outlaw" , "Wild ruffian" , "Bravo" , "Reckless guy" .)
