A married woman in the States (7)
I believe the answer is:
america
'the states' is the definition.
(I've seen this before)
'a married woman' is the wordplay.
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'woman' becomes 'erica' ().
'a'+'m'+'erica'='AMERICA'
'in' is the link.
(Other definitions for america that I've seen before include "Curious camera I take to the continent" , "Camera I take to the continent, oddly" , "Race aim (anag)" , "Land of the free and home of the brave?" , "Name of two continents" .)
