Earthenware pot or jar (5)
I believe the answer is:
crock
This clue is a double definition.
'earthenware pot' is the first definition.
(I've seen this in another clue)
'jar' is the second definition.
(I know that crock is a type of jar)
(Other definitions for crock that I've seen before include "Jalopy; dish" , "Pot or jar" , "(Broken) pot; one decrepit, injured" , "Broken piece of earthenware" , "Earthen jar" .)
