Draw down is a term used to describe the process of reducing or depleting something, usually a resource. In this case, it can be broken down into three words: DEPLETE, EARN, and GET. DEPLETE means to reduce or use up a resource, EARN means to gain or receive something in return for effort, and GET means to obtain or acquire something. Together, these three words form the phrase draw down, which describes the process of reducing or depleting a resource in exchange for something else.
