A view first seen in Virginia (5)
I believe the answer is:
vista
'a view' is the definition.
('vista' can be a synonym of 'view')
'first seen in virginia' is the wordplay.
'first' becomes 'ist' (ist resembles 1st).
'seen in' means one lot of letters goes inside another.
'virginia' becomes 'va' (US state abbreviation).
'ist' put inside 'va' is 'VISTA'.
(Other definitions for vista that I've seen before include "A view as seen through a long narrow opening" , "Broad prospect" , "Pleasant view" , "View (with avenue)" , "Panoramic view" .)
