Courage, pluck (5)
I believe the answer is:
nerve
I believe this is a double definition.
'courage' is the first definition.
(I know that nerve is a type of courage)
'pluck' is the second definition.
(I've seen this in another clue)
(Other definitions for nerve that I've seen before include "Courage, coolness in danger" , "Audacity (informal)" , "Boldness" , "Bottle, courage" , "Mettle, daring" .)
