Big vase (3)
I believe the answer is:
urn
'big vase' 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 "Large pot for coffee or tea" , "Run to get large vase" , "Tall stemmed vase" , "Spore-producing capsule of a moss" , "Container for tea or ashes" .)
