Takes a risk (5)
I believe the answer is:
dares
'takes a risk' 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 "Has the courage to do brave or dangerous thing" , "''Who ..., wins'' (SAS motto)" , "Makes bold, challenges" , "Risks" , "Challenges to do something dangerous" .)
