The term 'Barrel Part' can refer to four different components of a barrel: STAVE (5 letters), SLAT (4 letters), HOOP (4 letters), and BOTTOM (6 letters). A STAVE is a thin strip of wood that is used to form the sides of a barrel. A SLAT is a thin, flat piece of wood that is used to reinforce the staves. A HOOP is a metal band that is used to hold the staves together. The BOTTOM of a barrel is a flat piece of wood or metal that is used to close off the BOTTOM of the barrel.
