小知识
A rash is something that spreads like wild fire — red itchy skin or a series of unfortunate events. It can also describe an impulsive, wild decision.
As an adjective, rash has meant “quick, vigorous” since the 1300s by way of Scotland. The meaning shifted to “reckless” a few hundred years later, and can still be used that way — a “rash decision” is a sudden, not well thought out one. Rash, the noun that no one wants on their skin, came a few hundred years after that, but from the French word rache which at some point meant “ringworm.” Ringworm still gives us a red, itchy rash. Fun! Rash can also mean a lot of unpleasant things happening in a short amount of time, like robberies or earthquakes.

可能来自俗拉丁语*rasicare，刮，擦，来自拉丁语radere，刮，擦，词源同rat，eraser.先看单词eraser（橡皮；黑板擦），前缀e-表“向外”，词根ras表“刮、擦、削、刨”这类动作，-er为名词后缀，所以它的字面义就是“用来擦除的东西”。词根ras和单词rash同源，皮疹就是让你痒得非“抓、刮、挠”不可的东西。=可能来自俗拉丁语*rasicare，刮，擦，来自拉丁语radere，刮，擦，词源同rat，eraser.
