lose, leave behind

遺 is composed of the radical of 辵 (movement) and 貴 (expensive). 辵 carries the meaning of moving, while 貴 represents something of high value. Therefore, 遺 conveys the idea of moving a valuable object to another place. If one possesses something of high value, it is usually stored in a hidden place and not moved casually, unless it has been lost or discarded.
