Schooner pole (4)
I believe the answer is:
mast
'schooner pole' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mast that I've seen before include "Spar to support a sail" , "food for pigs" , "Pole on ship" , "Pole to support a sail" , "Nuts for pigs" .)
