Noble, a sporting venue (7)
I believe the answer is:
augusta
'sporting venue' is the definition.
The answer and definition can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'noble a' is the wordplay.
'noble' becomes 'august' (similar in meaning).
'august'+'a'='AUGUSTA'
Can you help me to learn more?
(Other definitions for augusta that I've seen before include "City of Georgia" , "Girl - state capital" , "Georgian city, noted for golf tournaments" , "Place in Georgia" , "Lady Bracknell" .)
