Table's gold dish seen first (7)
I believe the answer is:
plateau
'table's' is the definition.
(I've seen this before)
'gold dish seen first' is the wordplay.
I cannot really understand how this works, but
'gold' could be 'au' (Au is the chemical symbol for gold) and 'au' is found in the answer.
'dish' could be 'plate' (plate is a kind of dish) and 'plate' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for plateau that I've seen before include "plane" , "Area of livel high ground" , "Levelling off" , "Stop progressing" , "High flat land" .)
