Caterer's coffeepot (3)
I believe the answer is:
urn
'caterer's coffeepot' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for urn that I've seen before include "Vessel for making hot drinks" , "Pot for human ashes" , "Run to get large jar" , "Container for tea or ashes" , "Receptacle for ashes of the dead" .)
