程度衝出常規：極其、非常
這一支是把「跑出常規之外」用在「量」上——不是方向不對，而是走得太遠。
extremely · r · B2
extremely — used before an adjective or another adverb to say that something is true to a much greater degree than usual.
極其；非常
核心畫面
You can think of it as a word that points past the edge of the ordinary. Whatever line marks 'normal' for a thing, this word says the thing has gone out beyond that line — so far out that you notice it. Everything else follows from which way it goes out: further up (much more than usual) or simply off to one side (not like it usually is).
每件事都有一條「一般來說大概是這樣」的線，而這個字說的是——它跑到那條線外面去了，而且遠到你會忍不住注意。extra…更多收起
每件事都有一條「一般來說大概是這樣」的線，而這個字說的是——它跑到那條線外面去了，而且遠到你會忍不住注意。extra-（在…之外）加上 ordinary（平常的），字面就是「在平常之外」。剩下的差別只在往哪個方向出去：往上衝很遠，就是「極其、非常」；往旁邊偏，就是「反常、怪怪的」。From the word’s history
From Latin extraordinarius, 'out of (extra) the usual order (ordo, ordinem)' — literally outside the regular arrangement of things.
來自拉丁文 extraordinarius，由 extra（在…之外）+ ordo/ordinem（常規、次序）組成，字面是「在常規次序之外」。這個字根到今天還撐著整個字：不管是「非常」還是「反常」，講的都還是同一件事——它不在一般的次序裡面。
