Some Bedouin go to bar (5)
I believe the answer is:
ingot
'bar' is the definition.
(block of metal, eg a bar of gold)
'some bedouin go to' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'INGOT' is hidden within 'bedouin go to'.
(Other definitions for ingot that I've seen before include "Block of precious metal" , "Piece of cast metal" , "Bar, brick of metal" , "Form of gold or silver" , "Bar of bullion, for example" .)
