Thanksgiving decorations often include MAIZE, COB, CORNUCOPIA, and horn of plenty. MAIZE is a type of cereal grain, also known as corn, which is used to make flour, meal, and other food products. COB is the hard, central core of an ear of MAIZE, which can be used to make decorations. CORNUCOPIA is a symbol of abundance and prosperity, usually depicted as a horn-shaped basket overflowing with fruits, vegetables, and other goods. Horn of plenty is another name for CORNUCOPIA, referring to its shape. All of these items are popular decorations for Thanksgiving celebrations.
