Nebuchadnezzar for example daring (6)
I believe the answer is:
bottle
This clue is a double definition.
'nebuchadnezzar for example' is the first definition.
(I know that nebuchadnezzar is a type of wine bottle)
'daring' is the second definition.
(thesaurus)
(Other definitions for bottle that I've seen before include "Narrow-necked vessel" , "(Drink) container" , "See 11" , "Preserve" , "Glass container or slangy courage" .)
