Married man in AA in country (7)
I believe the answer is:
america
'country' is the definition.
(United States of America)
'married man in aa' is the wordplay.
'married' becomes 'm'.
'man' becomes 'eric' (I've seen this before).
'in' means one lot of letters goes inside another.
'm'+'eric'='meric'
'meric' put within 'aa' is 'AMERICA'.
'in' is the link.
(Other definitions for america that I've seen before include "Land of the free and home of the brave?" , "Camera I found in the continent" , "Song title shared by Sondheim-Bernstein and Paul Simon among others" , "North or South, it's a continent" , "Country bordering Mexico" .)
