I believe the answer is:

bottle

I'm a little stuck... Click here to teach me more about this clue!

'courage' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for bottle that I've seen before include "Glass liquid container or slang courage" , "Heart" , "confidence" , "Narrow-necked vessel" , "Device used by beer drinkers" .)

I've seen this clue in The Sun.
