A "trunk" typically refers to the main stem of a tree, which supports its branches and leaves. It is usually thick and sturdy, allowing the tree to grow tall and withstand various weather conditions. The trunk is essential for transporting water and nutrients from the roots to the rest of the tree. In addition to trees, the term "trunk" can also describe a large, strong container used for storage or travel. These trunks are often made of wood or metal and can hold clothing, personal items, or other belongings. They are commonly associated with travel, especially in the context of luggage or suitcases.
