Found in Maine a month before (7)
I believe the answer is:
augusta
'found in maine' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe there's a link between them I don't understand?
'a month before' is the wordplay.
'month' becomes 'August' (August is an example).
'before' is a charade indicator (letters next to each other).
'a' after 'august' is 'AUGUSTA'.
Can you help me to learn more?
(Other definitions for augusta that I've seen before include "Georgian city, noted for golf tournaments" , "22 [MAINE] 's capital" , "American city" , "US city" , "Algernon's aunt (Importance of Being Earnest)" .)
