Reckless lawman visibly embarrassed over wickedness (9)
I believe the answer is:
daredevil
'reckless' is the definition.
(thesaurus)
'lawman visibly embarrassed over wickedness' is the wordplay.
'lawman' becomes 'da'.
'visibly embarrassed' becomes 'red'.
'over' means one lot of letters go next to another.
'wickedness' becomes 'evil' ('evil' can be a synonym of 'wickedness').
'da'+'red'+'evil'='DAREDEVIL'
(Other definitions for daredevil that I've seen before include "Reckless person who enjoys danger" , "Lived, dear like rckless adventurer" , "rash" , "Dread evil, being a reckless person" , "Reckless person, thrill-seeker" .)
