Bottle; impudence (5)
I believe the answer is:
nerve
This clue is a double definition.
'bottle' is the first definition.
(both can mean courage)
'impudence' is the second definition.
(I know that impudence can be written as nerve)
(Other definitions for nerve that I've seen before include "Grit" , "Impudence; courage" , "Cheek; self-possession" , "Mettle, daring" , "Brass neck" .)
