Coffee vessel (3)
I believe the answer is:
urn
'coffee vessel' 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 "Water vessel" , "Spore-producing capsule of a moss" , "Large pot for coffee or tea" , "Vase; tea vessel" , "Large vessel for making coffee or tea" .)
