Big coffee dispenser (3)
I believe the answer is:
urn
'big coffee dispenser' 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 "Spore-producing capsule of a moss" , "Pot, vase" , "Run to get funeral vase" , "Funereal vase" , "Large pot for coffee or tea" .)
