The word 不止 is formed through the direct logical combination of its two constituent characters: 不, meaning "not", and 止, meaning "to stop" or "to cease". Conceptually, they are placed together to create the core idea of "not stopping", which inherently extends to notions of continuation, exceeding a limit, or going beyond a certain point. It is a conceptual compound where the negation modifies the action, picturing a state or action that does not come to an end at a presumed boundary.
