Will a drink from this give you courage? (6)
I believe the answer is:
bottle
'courage?' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bottle that I've seen before include "Nerve (sl.)" , "Pitcher perhaps" , "It keeps drink" , "cool" , "Container for liquids" .)
