Stumbling, otherwise, around bar (5)
I believe the answer is:
ingot
'bar' is the definition.
(thesaurus)
'stumbling otherwise around' is the wordplay.
'around' indicates a hidden word.
'INGOT' is hidden in the letters of 'stumbling otherwise'.
(Other definitions for ingot that I've seen before include "this must be cast" , "Block of, eg, gold" , "Form of gold or silver" , "Block of precious metal" , "Piece of cast metal" .)
