Dramatic scene: gold being taken on board (7)
I believe the answer is:
tableau
'dramatic scene' is the definition.
(I've seen this before)
'gold being taken on board' is the wordplay.
I cannot quite understand how this works, but
'gold' could be 'au' (Au is the chemical symbol for gold) and 'au' is present in the answer.
'board' could be 'table' (both can mean food) and 'table' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tableau that I've seen before include "picture that's striking" , "Living picture" , "Frozen stage scene" , "Dramatic scene (where the action is frozen?)" , "Dramatic setting" .)
