One way to hold this word: it assumes the thing will break one day, and asks which way it should fall when it does. A fail-safe machine falls towards stopping, towards the closed valve, towards the locked brake — the direction where nobody gets hurt. Read the two halves in order and the word is its own instruction: fail, then safe.
可以想成這個字一開始就承認：東西總有壞掉的一天。它問的不是「會不會壞」，而是「壞的時候往哪一邊倒」。fail-safe 的機器往「停下來」那邊倒，往關掉的閥門、鎖住的煞車那邊倒——倒向沒有人會受傷的方向。兩個字照順序讀，本身就是一句指令：先 fail（失效），然後 safe（回到安全）。
