可以想成你走到一個岔路口，前面的路突然分成兩條，你非選一條不可——而這一選，後面整趟路就此決定。crucial 的東西就是那個岔路口：整件事的成敗都吊在它身上，選錯就全盤不同。From the word’s history
From Latin crux, crucis 'cross'. Latin crux came to name a signpost where a road forks in two; Francis Bacon's phrase instantia crucis (1620) used that forking-road image for a decisive test — the point where you must choose and everything turns.
來自拉丁文 crux（十字、交叉），後來指路口那種「一條路分成兩條」的路標。培根在 1620 年用 instantia crucis（岔路口的實例）來講一個決定性的關鍵點——就是那個非選不可、一選就定生死的分岔處。
