Vase with a base (3)
I believe the answer is:
urn
'vase with a base' 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 "Run to get large jar" , "Source of tea" , "Large pot for making tea" , "Run to get Greek vase" , "Funerary vessel" .)
