Daring adventurer (12)
I believe the answer is:
swashbuckler
'daring adventurer' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for swashbuckler that I've seen before include "Gascon" , "Errol Flynn on film, for instance" , "One given to derring-do" , "To prepare explorer" , "Daring and romantic adventurer" .)
