Reckless and somewhat super-duper (5)
I believe the answer is:
perdu
'reckless' is the definition.
(I've seen this before)
'somewhat super-duper' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'PERDU' is hidden in the letters of 'super duper'.
'and' is the link.
(Other definitions for perdu that I've seen before include "secret" , "Concealed; lie in ambush" , "lost to sight" , "Concealed; reckless" , "in hiding" .)
