Large coffee maker (3)
I believe the answer is:
urn
'large coffee maker' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for urn that I've seen before include "A large vase as for human ashes" , "Tea vessel or ash container" , "Tall stemmed vase" , "Large pot for coffee or tea" , "Holder of the Ashes?" .)
