US state; capital Hartford (11)
I believe the answer is:
connecticut
I believe this clue is a double definition.
'us state' is the first definition.
(I've seen this before)
'capital hartford' is the second definition.
(I know that Connecticut has the capital city Hartford)
(Other definitions for connecticut that I've seen before include "The Nutmeg State" , "America" , "state of the union" , "State of NE USA" , "One of original thirteen US states" .)
