Still-life jug (4)
I believe the answer is:
ewer
'still-life jug' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ewer that I've seen before include "Oversized jug" , "Large, wide-mouthed jug" , "Large water jug" , "Water jug with wide mouth" , "Water-jar" .)
