Confident, daring (4)
I believe the answer is:
bold
I believe this is a double definition.
'confident' is the first definition.
(similar in meaning)
'daring' is the second definition.
(I've seen this in another clue)
(Other definitions for bold that I've seen before include "Daring, courageous" , "Like heavy type" , "Suspended; kept cold" , "Thick and heavy (type)" , "Courageous, confident" .)
