Rounded vase (3)
I believe the answer is:
urn
'rounded vase' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for urn that I've seen before include "Container for tea or ashes" , "Receptacle for ashes of the dead" , "Water vessel" , "A ceremonial vase as for human ashes" , "Receptacle for human ashes" .)
