The word "上篮" is formed by combining the character "上" (shàng), meaning "to go up" or "upward", with "篮" (lán), meaning "basket", specifically referring to a basketball hoop. This creates a verb-object compound where "上" acts as the verb describing the action, and "篮" serves as the object denoting the target, resulting in a term that literally means "to go up to the basket" and specifically denotes the basketball shot known as a layup.
