Excellent produce limited for example over country (7)
I believe the answer is:
georgia
'excellent produce' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'limited for example over country' is the wordplay.
'limited for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin; 'limited' suggests a short form).
'over' says the letters should be written in reverse.
'country' becomes 'orgia' (I can't explain this - if you can you should believe this answer much more).
'eg' in reverse letter order is 'ge'.
'ge'+'orgia'='GEORGIA'
Can you help me to learn more?
(Other definitions for georgia that I've seen before include "Girl on my mind" , "part of US or USSR formerly" , "Its capital is Tbilisi (or Atlanta)" , "Southern US state" , "Country on the Black Sea, where Stalin was born" .)
