Run off to get receptacle (3)
I believe the answer is:
urn
'receptacle' is the definition.
(I know that urn is a receptacle)
'run off' is the wordplay.
'off' indicates an anagram.
'run' is an anagram of 'URN'.
'to get' is the link.
(Other definitions for urn that I've seen before include "Container for tea or ashes" , "Receptacle for human ashes" , "Large vase for holding ashes of dead person" , "Run to get funeral vase" , "Vase-shaped vessel" .)
