Courage displayed in vessel? (6)
I believe the answer is:
bottle
I believe this is a double definition.
'courage' is the first definition.
(bottle can mean courage)
'vessel?' is the second definition.
(I know that bottle is a type of vessel)
'displayed in' is the link.
(Other definitions for bottle that I've seen before include "Heart" , "The spirit" , "Pitcher perhaps" , "Glass liquid container or slang courage" , "Device used by beer drinkers" .)
