Is bold (5)
I believe the answer is:
dares
'is bold' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dares that I've seen before include "Ventures" , "''Who ..., wins'' (SAS motto)" , "Challenges to do something dangerous" , "Has the courage to do brave or dangerous thing" , "Risks" .)
