Food for hogs (4)
I believe the answer is:
mast
'food for hogs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mast that I've seen before include "Pole to support a sail" , "Pole on ship" , "Large transmitter" , "Nautical pole" , "One carries the sails of a ship" .)
