Run off to get receptacle (3)
I believe the answer is:
urn
'receptacle' is the definition.
(I've seen this in another clue)
'run off' is the wordplay.
'off' is an anagram indicator.
'run' with letters rearranged gives 'URN'.
'to get' acts as a 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" .)
