Before lunch, man a country (7)
I believe the answer is:
america
'country' is the definition.
(I know that America is a country)
'before lunch man a' is the wordplay.
'before lunch' becomes 'am' (I've seen this in other clues).
'man' becomes 'eric' (I've seen this before).
'am'+'eric'+'a'='AMERICA'
(Other definitions for america that I've seen before include "Take care and aim for the continent" , "Race aim (anag)" , "World power" , "Song title shared by Sondheim-Bernstein and Paul Simon among others" , "The USA" .)
