The kanji 尽 is a phono-semantic compound (形声文字). The left side is a simplified form of the character for "river" (originally depicting a river flowing). The right side is "to kneel" or "to prostrate." The original meaning was likely connected to the idea of the river flowing to its end, or emptying into the sea. Over time, it evolved to represent the broader concepts of depletion, completion, and the act of putting forth all effort.
