A panhandle state (5)
I believe the answer is:
idaho
'a panhandle state' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for idaho that I've seen before include "part of US near Washington" , "My Own Private -- (1991 film)" , "American state, capital Boise (5)" , "US state, capital Boise" , "O, I had a change in this state" .)
