The term 'Pitcher Part' refers to the four components of a pitcher. The first part is the LIP, which is the top edge of the pitcher that helps to contain the liquid inside. The second part is the SPOUT, which is the opening through which the liquid is poured. The third part is the HANDLE, which is used to hold and pour the liquid. Finally, the fourth part is the EAR, which is a small HANDLE on the side of the pitcher that helps to balance it when pouring.
