County in England or New Jersey (5)
I believe the answer is:
essex
'county in england or new jersey' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for essex that I've seen before include "Harlow's county" , "Queen's favourite" , "Southeastern English county" , "Favourite of Elizabeth I" , "County, its tasteless moneyed Man" .)
