Auditor's painting jug (7)
I believe the answer is:
pitcher
This might be a double definition.
'auditor's painting' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'jug' is the second definition.
(I know that pitcher is a type of jug)
Can you help me to learn more?
(Other definitions for pitcher that I've seen before include "Baseball bowler and large jug" , "large vessel" , "American player" , "Earthenware vessel" , "American sportsman" .)
