Buckeye's home (4)
I believe the answer is:
ohio
'buckeye's home' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ohio that I've seen before include "Turning engine part" , "E. central US state" , "American river" , "State of the union" , "Midwestern US state and river" .)
