cumulative 和 accumulative 的差別在哪裡？如果不好說明，請提供一些例句。

@yyyynn Cumulative refers to amassing or building up over time; growing by successive additions. I've used cumulative in more conceptual contexts, for example talking about data or cumulative assessments, a test testing various chapters, topics, or lessons learned throughout a set period of time.

Accumulative refers to the result of accumulating. I believe accumulation refers to a more physical form of building or gathering such as accumulating debt or wealth or accumulating so many things that they topple over. I would use it for things which you gather that actually have mass.
