Rural skyscraper (4)
I believe the answer is:
silo
'rural skyscraper' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for silo that I've seen before include "Store for grain or fodder" , "Storage unit for animal feed" , "Tower for storing grain" , "Launch site" , "Farm store; soil (anag.)" .)
