Level ground dish of gold (7)
I believe the answer is:
plateau
'level' is the definition.
(thesaurus)
'ground dish of gold' is the wordplay.
I cannot really see how this works, but
'dish' could be 'plate' (plate is a kind of dish) and 'plate' is located in the answer.
'gold' could be 'au' (Au is the chemical symbol for gold) and 'au' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for plateau that I've seen before include "Stop progressing" , "High tableland" , "Area of level high ground" , "High plain" , "Flat raised land" .)
