Country girl in pursuit of a male (7)
I believe the answer is:
america
'country' is the definition.
(United States of America)
'girl in pursuit of a male' is the wordplay.
'girl' becomes 'erica' ().
'in pursuit of' means one lot of letters go next to another (some letters chase after others).
'male' becomes 'm' (common abbreviation).
'a'+'m'='am'
'erica' put after 'am' is 'AMERICA'.
(Other definitions for america that I've seen before include "Camera I turn on the continent" , "Camera I used in New World" , "country targeted by 3 [ROMNEY]" , "United States" , "Camera I take to the continent, oddly" .)
