A bundle bound is a collection of items that are tied together. The term can be broken down into three parts: SHEAF (5 letters), BALE (4 letters), and WAD (3 letters). A SHEAF is a group of stalks of grain or grass that have been cut and bound together. A BALE is a large bundle of material, such as hay, straw, or cotton, that has been tightly compressed and bound together. Lastly, a WAD is a small, compact mass of material, such as paper, cloth, or tobacco, that has been rolled or pressed together. All three terms are used to describe a bundle bound, which is a collection of items that have been tied together.
