The term is formed through a layered, logical accumulation of negation: it starts with "one" or "the whole" (一), applies "not have" or "lack" (无) to that entirety, and then specifies that what is lacked is "all that is possessed" (所有). The construction moves from the general to the specific, painting a complete picture of absolute absence, first establishing the scope (all), then denying existence within it, and finally clarifying that the denial pertains to everything one could own or hold.
