Piece of pottery one throws (7)
I believe the answer is:
pitcher
This clue could be a double definition.
'piece of pottery' is the first definition.
(ceramic vessel)
'one throws' is the second definition.
Although both the answer and 'throws' are nouns, they are not in the same form of the noun. However, I know that 'throws' relates to this answer.
Can you help me to learn more?
(Other definitions for pitcher that I've seen before include "US sportsman" , "Baseball player; big jug" , "Baseball player throws the vessel" , "Baseball thrower or water jug" , "that can hold his drink" .)
