Earthen pot or jar (5)
I believe the answer is:
crock
I believe this clue is a double definition.
'earthen 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 "Decrepit person" , "Broken piece of earthenware" , "Jalopy; dish" , "(Broken) pot; one decrepit, injured" , "Large pot" .)
