Container for ashes (3)
I believe the answer is:
urn
'container for ashes' is the definition.
(ashes are typically stored in an urn)
This is all the clue.
(Other definitions for urn that I've seen before include "Without cost; last word of Tempest" , "Water vessel" , "Large ornamental vase" , "Source of tea" , "Receptacle for ashes of the dead" .)
