Stately potato? (5)
I believe the answer is:
idaho
'stately potato?' 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 "The Gem State, known for its potatoes" , "My Own Private -- (1991 film)" , "North-western US state" , "Rocky Mountain state" , "One of 22 Across, capital Boise" .)
