The Beehive State (4)
I believe the answer is:
utah
'the beehive state' is the definition.
('Utah' can be a synonym of 'beehive state')
This is the entire clue.
(Other definitions for utah that I've seen before include "Mormon US state" , "member of union" , "The American Morman state" , "The American Mormon state" , "US state settled by the Mormons" .)
