“last straw”源于伊索寓言中“压垮骆驼的最后一根稻草”（It's the last straw that breaks the camel's back.）的典故：骆驼已承载大量重物，一根看似微不足道的稻草，却成为压垮它的“最后一击”。18世纪末，该短语从完整典故中简化为“last straw”，进入英语日常用语，核心比喻义沿用至今——不强调事物本身的重量，而突出其“累积压力下的最终触发点”。

核心语义

唯一核心语义：在一系列令人烦恼、沮丧的事件后，最终导致彻底崩溃、忍无可忍的那件小事、最后一击、忍无可忍的不断发生的事或挑衅。

关键点：必须存在“前文累积的多个问题”，“last straw”本身通常是小事，但作用是“压垮骆驼的最后一击”，而非单独引发问题的大事。如：

The company had already cut salaries and laid off workers; the sudden rise in raw material prices was the last straw.
