Hog holder (3)
I believe the answer is:
sty
'hog holder' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sty that I've seen before include "Farmyard enclosure" , "Animal pen" , "Enclosure for swine" , "Eye ailment or pig's home" , "Sore on eyelid" .)
